What’s the best tourist SIM card for Japan (2024 guide)

By: Author Kris

Posted on Last updated: January 22, 2024

If you’re headed to Japan and want to stay connected while exploring, we’ve got you covered with the top tourist SIM cards. No need to worry about losing touch with your loved ones or missing out on those Insta-worthy moments.

We’ve spent a lot of time in Japan and traveled all over the country. The first trips we would very often come across a “Handy” phone in our hotel room – a phone we could use throughout our stay. But those days are long gone now.

Nowadays, if you want to stay connected, you better have a local SIM card if you don’t want to rely on public hotspots. And trust me, from experience, we can assure you that a local SIM card is still highly recommended.

There are several spots offering free internet, mainly in the larger cities, and handy apps to connect to WiFi hotspots for free. We share more information on this app in this article. Still, there are still plenty of places that require a data subscription for internet usage.

Whether you prefer the convenience of ordering physical SIMs online and picking them up at the airport or exploring the innovative world of eSIMs, there are numerous ways to ensure you stay connected on your journey.

Japan Tourist SIM cards – The top choices

In this article, we discuss no less than 30 different Japan tourist SIM cards.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

We discuss all the details of the SIM cards further down in this article but here are our top choices:

For the occasional data user

Most SIM cards offer unlimited data but all providers have implemented a fair usage policy. If you consume more than what is covered by the fair usage policy your data speed will be reduced. Sakura Mobile cannot share the exact details of the fair usage policy, therefor we recommend them for occasional use. Their prices are very competitive but they cannot be used for video streaming or as a hot spot for your laptop.

If you just want to make sure that you can fall back on your data plan if you need it but you already know that you will only have to use it occasionally, these are your best options.

Short stays

At JPY ¥4,000 for 8 days the SIM cards provided by Sakura Mobile are reliable and very cheap. 

The SIM card offers unlimited high-speed data at 4G or 3G speeds.  You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country.

Thanks to the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there. If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible (see our FAQ below) with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

Longer stays

If you are 2 of 3 weeks in japan.

For stays of 2 or 3 weeks , you’re in most cases also best off 16 or 21-day cards of Sakura Mobile that can be found on Klook.  At JPY ¥6,000 and JPY ¥6,500 they are the cheapest options that can be found for these durations.

Both SIMs offer unlimited high-speed data at 4G or 3G speeds.  4G is offered in major cities while the 3G is applicable in more rural areas. You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country. It has a coverage of over 99%.

Once you have read through the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there.

If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

If you are longer than 24 days in Japan

If you will be in Japan longer than 24 days the 30-day card of Simcard GEEK that costs JPY ¥4,980 is a good buy.  The card comes with 7GB of high-speed data which should be sufficient to cover your needs.  This SIM card also connects to the NTT Docomo network which is generally recognized as Japan’s best network.

Simcard GEEK has a fair usage policy of 3GB/day.

For the heavy data user

If you want to be online the whole day,  enjoy streaming music, or watch YouTube videos, you’re better off with the below SIM cards.  This may also be the case for those who will be sharing your data plan with friends or family members, maybe by means of a mobile WiFi device.

These SIMs also have a fair usage policy. In this case, however, you know the details of the policy and can therefore pay attention to it so that you are not faced with surprises.

Mobal offers SIM cards for 8 or 16 days with an unlimited data plan .  The cards have a fair usage policy which limits high-speed data to 3GB per day. 3GB is quite a lot, it will allow you to browse the internet for 36 hours, stream 600 songs, or watch 6 hours of standard definition video. 

Consuming this amount of data in one day would probably mean that not much time is left to see the many stunning sights Japan has to offer.

Mobal has a SIM with an unlimited data plan for 31 days.   This card has a fair usage policy which limits high-speed data to 3GB per day. 3GB is a lot, in the previous paragraph we gave a small overview of what exactly you can do before you reach this threshold. 

If you go out and discover the city you will probably never consume that much data in one day and if you stay in your hotel you can use the WiFi provided by the hotel.

Sakura Mobile

Sakura Mobile is a reputable Japanese company that specializes in providing wireless services for visitors to Japan. They offer a range of affordable solutions to keep you connected throughout your stay.

They offer English support. Our support question was answered quickly, correctly, and in clearly understandable English.

One standout feature of Sakura Mobile is its compatibility insurance option. For an additional fee of 500 JPY, you can add this insurance to your purchase if you’re unsure whether their SIM will work with your device. This provides peace of mind and ensures that you’ll be able to stay connected without any hiccups.

In the unlikely event that you do encounter connectivity issues, Sakura Mobile offers a solution to those who took the insurance option – an upgrade to a Pocket Wi-Fi device at no extra cost. Alternatively, if you prefer, they can also provide a refund.

You have multiple options when it comes to ordering Sakura Mobile SIMs. You can either purchase them through Klook or directly on their corporate website . While the widest range of options is available on their own site, it’s worth noting that Klook offers certain exclusives not found on the corporate website.

On the other hand, when ordering directly, you can choose from more pick-up locations or have the SIM shipped to any address within Japan, including hotels.

Size : Multi-size SIM cards. Normal, Nano or Micro sim.

Network :  NTT Docomo (3G & 4G)

Shipping :  When you order through Klook the SIM can be collected at Terminal 3 (the International terminal) of Haneda International Airport or Terminal 1 and 2 of Narita International Airport. There is also a pick-up location in the arrival lobby of the Kansai airport.

If you order direct you can have the SIM delivered to hotels and Airbnb’s or collect it at the airport (Haneda, Narita, Kansai, Chubu, New Chitose) or at the office in Shinjuku.

Activation : No activation is required for these SIM cards. They’re ready to use. You just need to insert the SIM and set the APN.  You can download a document that explains how to do this.

Available direct :

Available through Klook :

Japan SIM cards with pick-up abroad (via Klook)

Here are a few extra options for those who live in Thailand, Malaysia, Hong Kong, Vietnam or India.

The below providers offer SIM cards that are either shipped to your home or that can be collected at your airport of departure.

Personally I would prefer to pick-up my SIM in Japan.  This has the advantage that somebody can assist you with setting it up and in the unlikely event that it doesn’t work, you would be able to look for an alternative or arrange a refund on the spot.

A pick-up abroad might, however, be a convenient option if you don’t want to lose time collecting your SIM upon arrival.

Buying a SIM card in Japan

Don’t worry if you’re already in Japan when you’re reading this. 

It’s also possible to buy a tourist SIM card in BIC Camera and Yodobashi Camera stores as well as at Narita and Haneda airports. 

You can even order one online and pick it up in several locations in downtown Tokyo, Kyoto, Osaka as well as other cities.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport terminal 3 (see here and here ).  The sales points from the operators will likely be able to better assist you and give you advice while the stores from BIC camera will likely be cheaper.

In the cities

Another option to buy a SIM card in Japan would be to head to one of the BIC Camera or Yodobashi Camera stores in the cities. 

They sell various prepaid SIM cards for Japan tourists.  Usually, someone will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they would at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is. But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

Finding these stores is easy.  Your hotel should be able to tell you the nearest one or you can use Google Maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend.  It is a fun experience during which you can marvel at all the electronic gadgets that are for sale.

But maybe you prefer to compare the various options from the comfort of your hotel room.  This is possible as well. 

You can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

They have a very informative website and offer English support in case you have any additional questions. 

Japan eSIMs

Good news if you have a modern phone that supports embedded SIMs (eSIMs). You no longer have to worry about fiddling with your phone to replace the SIM card. All you have to do is click a link or scan a QR code.

Your SIM can stay in your device and you can switch between your own cellular plan and the Japanese plan. Super convenient and super easy.

Four providers offer eSIMs :

Simcard GEEK

Airalo esims.

Frewie offers 2 eSIMS for use in Japan. When ordering a Frewie eSIM through Klook you will get a confirmation mail with a QR code to activate your eSIM. The mail is sent within 24 hours of your purchase.

The Frewie eSIM is a data-roaming SIM that connects to the Docomo network in Japan. It’s not a native Docomo eSIM, you will need to activate data roaming for it to work. Because it uses roaming it can be somewhat slower than the above eSIM options from Simcard GEEK.

One SIM works only in Japan, the other works in Japan & South Korea. Both are data only. The data package varies with the duration of the SIM.

Japan SIM card for longer stays

For a short stay, you’re best off with a prepaid SIM card but if you’re staying in Japan for several months you could consider an unlimited long-term plan.  

Japanese providers are known to have a lot of red tape.   

A contract with them usually requires a lot of paperwork and a commitment of 2 years. For some, you even need to have a residence visa and/or a Japanese bank account.

Two providers offer long-term SIM plans :

Mobal offers an alternative to the red tape. 

Their long-term plan comes with no minimum duration, no activation, and no termination fee. 

The customer service team speaks English, is super-responsive, and you can easily order the SIM card online.

This is what you will get:

Japanese Phone number : A real Japanese phone number starting with 070, 080 or 090 (Softbank).  A voicemail service is included.

Free calls : All incoming calls and texts are free. Outgoing calls to other Softbank customers (including Mobal customers) are free from 1 AM to 9 PM.

Shipping :  Shipping is always free but not available to all countries.  If shipping is not available to your country you can simply collect your sim for free, at one of the many pick-up locations.  There are locations at the airports and in Tokyo, Osaka, Kyoto and other major cities across Japan.

Shipping of voice+text sims requires that a copy of your ID is sent to Mobal at the time of your order. 

If you don’t want to share these details online you can pick up your package in Japan. All details about shipping and pick-up locations are extensively explained on the website .

Activation : To activate your SIM follow the activation instructions provided with your sim.  During business hours the activation should be processed within 2 hours.

Upgrade data plan : The data+voice SIM has 7GB of data at 4G speed per calendar month.  If you want more data at high speed you upgrade your plan in your online account.

Fair usage policy : If you use more than 7GB in one month your data speed will be reduced to 128kpbs for the remainder of the calendar month.

FAQ About Tourist SIM Cards for Japan

Will your phone work in japan .

Before you buy a SIM you need to be sure that your phone is compatible with Japan’s telecom network. It needs to be able to operate on one of the bands used by the telecom operators in Japan. 

Check the technical specs of your phone to see what bands are supported and see if there’s a match with the bands that the operators are using. We’ve listed all of them in the following section.

Your phone will also need to be unlocked.

If you don’t want to do this manually you can find pages online ( like this page ) where you can select your phone and the network operator to verify if they’re compatible.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. Rakuten Mobile used to be a virtual operator but started building out its own network a few years ago. Today it covers about 94% of the population.

All other operators are virtual and use one of the existing networks. The tourist SIM cards we discussed in this article all work on either the Softbank or NTT Docomo network.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second although they are not far behind. Both these networks cover 99% of Japan (population-based).

These are the bands used by the Japanese operators:

Rakuten Mobile

Pocket WiFi device vs Tourist SIM card

One big perk of using a pocket WiFi device is that you can stay connected without having to mess with your phone.

No need to worry about changing your settings. Just remember to turn off your data connection to avoid those annoying roaming fees. With your SIM card still in the phone, you can stay connected with friends, family, work buddies, and anyone else who has your number just like you’re back at home.

If you want people to be able to contact you anytime, a pocket WiFi device is a great option.

Another advantage of pocket WiFi devices is that they let you connect multiple users at once (usually up to 10!).

Batteries of pocket WiFi devices usually last no more than a day. This is probably the biggest disadvantage. It is one more device that you need to charge on a daily basis.

Interested in Pocket WiFi devices?

See which ones you can rent in Japan . Or if you are going to use this often, you can buy your own device , just like us.

Which size of SIM card do you need

SIM cards have become increasingly smaller over the years. First, we had the standard SIM, then the Micro SIM and nowadays almost all modern phones use a Nano-SIM

Usually, providers use multi-size (3-in-1) SIM cards that are compatible with all phones.  Others only offer 2-in-1 (Micro and Nano) which means they will still be compatible with most current models. 

The technical specs of your phone will show what SIM you need.

In some cases, you will need to specify the requested SIM size with your order.

Free WiFi in Japan

You can easily find free WiFi at many places in Japan. Coffee shops like Starbucks, metro stations in all major cities, and JR train stations offer this convenient service.

Connecting to public WiFi networks was a pain the first time we were in Japan. Not only did we, have to do it over and over again. We also couldn’t get the connection to work for half of the time.

But now there’s a great app called Japan WiFi Auto-Connect that takes care of all the hassle for you. It automatically connects your phone to selected public WiFi hotspots. Only the trusted ones managed by reliable companies or authorities are used by the app for security reasons.

The app worked perfectly for 90% of the time during our last trips. Whenever we walked into a metro station or train station the phone usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple and makes free WiFi much more reliable for foreigners.

Still, I suggest not depending on free WiFi entirely, just like we don’t. As you move away from the big cities, finding reliable Wi-Fi spots becomes harder.

And even in the major cities, I find it super handy to have internet access all the time so I can look up stuff whenever something pops into my head – not just when I stumble upon a hotspot.

It’s a matter of convenience, but SIM cards are so cheap that I think it’s worth it.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There’re many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

Why Buy a SIM Card For Japan?

Buying a sim card for japan – things to consider, where to buy a sim card for japan, best japan sim card providers, what is the best sim card in japan for tourists, final thoughts on getting a sim card for japan.

In today’s age, a smartphone is an essential travel companion. It helps you translate that tricky kanji on a menu, navigate through Tokyo’s bustling streets, find a local date or instantly share your trip highlights on Instagram. 

But, relying on your native SIM to get online in Japan could mean inconsistent service or excessive charges. This is why getting a SIM Card for Japan is crucial.

But there’s no one-size-fits-all solution when it comes to choosing the right SIM cards for travelling Japan . Let’s delve into the vital considerations for choosing a SIM card in Japan.

While everyone loves a good deal, don’t let a cheap initial package fool you. Sometimes, the initial cost might be low, but the subsequent top-ups might burn a hole in your pocket. For instance, some providers may offer a SIM for just ¥1000, but data top-ups could cost a lot more.

Monitor your daily data usage before your trip and consider that you might well use a lot more while travelling. For instance, streaming the cherry blossom festivals might use more data than you anticipate, as will having to translate more or less every conversation…

Japan is a surreal mix of urban cities and rural landscapes. While Tokyo might have impeccable internet coverage, the remote villages in Kyoto might not. Research is pivotal here so know precisely  where you will be staying in Japan , and try to find a provider who offers a good level of courage across all of these areas and regions.

Bureaucracy

Acquiring a SIM in Japan is usually a seamless process, but always be ready with your identification just in case.

Always check the SIM’s lifespan. If you’re in Japan for a 3-month internship, ensure your SIM doesn’t expire before that. Many tourist-friendly SIMs have a 7, 14, or 28-day lifespan on them.

A new country, a new contract, a new piece of plastic – booooring. Instead, buy an eSIM!

An eSIM works just like an app: you buy it, you download it, and BOOM! You’re connected the minute you land. It’s that easy.

Is your phone eSIM ready? Read about how e-Sims work or click below to see one of the top eSIM providers on the market and  ditch the plastic .

You may already know that Japan is something of a capitalist, consumerist mecca, and there is no shortage of places to buy things. As such, Japan offers an abundance of places to purchase a tourist-friendly SIM card:

In case you don’t know what an eSIM is , it’s an electronic, non-physical SIM; a SIM card without a SIM card. Instead of opening up your phone, and slotting in a new tiny little plastic SIM, you simply download the e-SIM package onto your phone just as you would an app or piece of software.

Pre-flight purchases is a great advantage, and for this reason, we LOVE eSIM. However, be sure that your device is eSIM compatible.

In The Airport

A classic option for buying a travel SIM is to buy it at the airport as soon as you land. Most modern airports have SIMs and phone kiosks sat just outside of the baggage reclaim sections offering instant, easy SIM access to travellers. Often, the staff here speak some English and will get you connected right away.

However, everything for sale in an airport is at a jacked-up price including airport SIMs. You can usually get a much better SIM deal from a wider offering of Japanese SIM providers once you get away from the airport into the city.

Furthermore, if you land at a peak time the airport SIM kiosks can be mega-busy.

There are cell phone stores across Japan and you can find at least one in every neighbourhood inside of a major city. Then electronic stores like Bic Camera, or Yodobashi offer a wide variety of SIM cards, and some convenience stores like Seven-Eleven (7/11) sell SIM cards too. However, if you want to buy in a store do ensure that you have your passport ready for verification.

Vending Machines

Japan’s efficiency is evident with its tech-savvy vending machines, even offering SIM cards in certain locations. These vending machines in Japan have some very strange things on sale which we would rather not go into here…

Purchasing online before your trip ensures you’re prepared and ready to get online upon arrival as soon as you switch your phone back on. While many Japanese-specific SIMs might not be available internationally, global providers like OneSim are and can be bought at home.

There’s a diverse array of SIM card options in Japan, from well-known international network providers to specialized carriers exclusive to the country.

Here are some top Japan SIM card picks:

Established in 2010 and based in Palo Alto, California, GigSky is a mobile technology firm that specialises in providing e-SIM and SIM card data services to travellers across the globe. Distinguishing itself from the majority of eSIM providers, GigSky operates as an independent Network Operator, collaborating with over 400 carriers worldwide.

GigSky offers a range of packages for Japan including a tasty ‘try before you buy’ deal that gives you 100MB of data for 7 days.

• 1GB – $5.49 – 7 Days
• 3 GB – $15.49 – 15 Days
• 5 GB – $25.99 – 30 Days
• 10 GB – $49.99 – 30 Days

OneSim are a Boston-based SIM provider who have been specialising in traveler-friendly international SIM packages for some time now. Whilst they don’t offer a specialised Japan SIM card, they do have a different array of International SIM cards that will work in many different countries – including Japan.

• Offers coverage in 150+ countries with free incoming calls on an EU number in most.
• SIM + Data Packages from $13.00.
• No expiration date.
• Offers coverage in Japan + Asiatic countries.

HolaFly is an eSIM provider based in Spain and headquartered in the very hip and trendy city of Valencia. They offer affordable, generous eSIM packages in over 120 destinations by partnering with local carriers worldwide to ensure reliable and accessible data packages for travellers.

To explore, and purchase HolaFly’s eSIM packages, travellers can visit their website or download the HolaFly app, and search for their destination. It covers a bunch of destinations if you’re travelling further into Asia and presents all the relevant information, including pricing, data amount, and expiry periods, in a clear and easy-to-understand format.

Let’s look at the perks of HolaFly’s Japan SIM Packages;

• Keep your WhatsApp number on your cellphone.

The package types are simple. All offer unlimited data over a specified period of days. The 5-day package costs $19.00 and the $90.00 package costs $99.00

Nomad is essentially a digital eSIM marketplace that connects global travellers with affordable data plans almost anywhere in the world, without the need for a plastic SIM.

In order to use Nomad, users can simply browse the Nomad website’s eStore and look for suitable eSIM packages. However, users will get a better browsing experience if they download the Nomad app onto their device instead and this is exactly what we did when using Nomad.

Let’s look at Nomad’s Japan SIM Packages;

Nomad’s unlimited data plans begin at $9 USD for 1 day and range up to $36 for 10 days. They also offer limited plans such as 10GB for 10 days for $22.00.

Sakura Mobile

Sakura Mobile offers a variety of plans, including data-only SIM cards, voice + data SIM cards, and even pocket Wi-Fi devices. This makes them a very versatile choice for different types of users of travellers.

Let’s take a look at some of their top Japan travel SIM card packages;

• 8 days $41 Unlimited
• 15 days $50 Unlimited
• 30 days $68 Unlimited

IIJmio offers a variety of prepaid data-only plans as well as voice plans. Crucially though, IIJmio offers short-term data SIM cards for tourists or visitors including their 1GB per day for 30 days package at $30.00.

Of course, 1GB of data is simply not going to be enough for some of you out there.

Japan, with its mix of traditional, and ultra-modern attractions, offers an experience like no other. There is so much to see, do, experience, and eat. And it is guaranteed to prove to be a trip of a lifetime.

To get the most out of your Japanese journey, just be sure to equip yourself with a reliable SIM card before you go. Whichever provider you select, we’re eager to hear about your experiences in the Land of the Rising Sun.

Oh, one more thing. Make sure you can actually use your phone by keeping it charged with a Japanese travel adapter !

In order to stay connected in Japan during your travels, use a SIM card. This article features seven SIM cards ideal for a short stay in comparison with using portable Wi-Fi routers, as well as information regarding eSIM.

There are several ways to access the Internet in Japan. The most inexpensive method would be to use free Wi-Fi, although its availability is limited and can expose users to vulnerabilities.

A SIM card for travelers or portable Wi-Fi router comes in handy in these situations. While the latter can handle a large amount of data, carrying the device around may require some effort.

Alternatively, a SIM card may only handle a little data and is more complicated to set up than a portable Wi-Fi. But it is far easier to carry and cheaper than a router.

This article features seven SIM cards that will support your short-term trip to Japan. We've also included information on eSIM services and inexpensive portable Wi-Fi routers that are an alternative to SIM cards.

Those planning a long-term stay in Japan should check out this MATCHA article .

Top 7 SIM Cards to Use in Japan

While there are many types of SIM cards to use when traveling in Japan, the following is a list of five recommended providers and two places to purchase them.

1. mobal SIM Cards

mobal , a long-established company headquartered in the UK, handles SIM cards for travelers to Japan.

They offer various SIM card plans, the cheapest with unlimited data costing 4,730 yen for 8 days. Please note that data speed may be reduced after exceeding 3GB per day.

Mobal cards can handle about the same amount of data as pocket Wi-Fi routers. Moreover, there is no shipping fee for worldwide customers , so overseas visitors can receive the card in their home country before arriving in Japan.

The company also handles Voice SIM , which comes with a Japanese telephone number . The duration is 30 days for 7GB costing 7,920 yen and up. Also, the trending eSIM is available for 8 days for 1GB starting at 1,920 yen.

2. Sakura Mobile SIM Card

Sakura Mobile is a popular service for English-speaking people who are traveling or staying in Japan for long periods.

Their SIM cards offer unlimited data (data speed may be reduced after exceeding 2GB per day) and cost 4,950 yen for 8 days. Although it may seem expensive compared to mobal, Sakura Mobile is known for its top-notch customer support.

The company will answer questions in advance and offer consultations during the trip if you have any problems. If this is your first trip to Japan or first time using a SIM card, we recommend choosing Sakura Mobile!

They also offer an eSIM service. While prices vary depending on the period of use, a 10-day package with 5GB data costs 3,350 yen as of August 2023.

Nippon SIM for Japan is provided by DHA Corporation and is available on Amazon.

A 30-day plan with 3GB data costs 1,980 yen. There are other plans with a wide variety of duration and data.

Since the capacity is small, this card is suitable for those who don't use much data and looking to buy a cheap SIM card.

4. IIJmio Travel SIM

Those planning to purchase a SIM card during their trip should look for IIJmio Travel SIM . It is sold at major electronics stores in most large cities, such as Bic Camera, Yodobashi Camera, and Kojima .

This is an open-priced item with costs varying by store. As of August 2023, a 30-day card with 3GB data is sold for 2,480 yen at Bic Camera.

IIJmio is a low-cost SIM service provider that is well-known in Japan.

5. B Mobile Visitor SIM Card

B Mobile Visitor SIM can also be purchased on Amazon . It is also available on the company's official website. The price is 1,980 yen for a 10-day card with 5GB of data.

Please note that B Mobile Visitor SIM has an additional postage charge. 370 yen will be added to cards sent to Japanese airports and 520 yen for cards sent to hotels.

6. SIM Cards Offered by Klook

Residents of southeastern or eastern Asian countries should check Klook , an experience booking site.

Klook also sells various SIM cards that are suitable for a trip to Japan. Most of them can be sent to various Asian countries, so please take a look!

7. SIM Cards at Airports

If you forget to purchase a SIM card in your home country, don't worry! In recent years, major Japanese airports are provided with SIM card vending machines.

For example, a 6-day SIM card with 1GB of data is sold for about 2,000 yen at vending machines in Narita Airport. Please check the official website for additional details.

eSIM: An Alternative to Physical SIM Cards

One of the concerns about using a SIM card is the risk of losing the SIM card when replacing it. After all, SIM cards are very small, measuring only 1 to 3 millimeters in size.

Recently, eSIM has been trending because it can be used without replacing the physical SIM card. In the U.S., the iPhone 14 series designed for eSIM use was released in 2022, and other carriers are expected to follow.

Companies in Japan are also offering this service.

As mentioned above, mobal provides this service for 1,920 yen and up (8 days with 1GB data). The price at Sakura Mobile is 3,350 yen for 10 days with 5GB of data. Nippon SIM for Japan also offers eSIM.

If you're using a smartphone that supports eSIM, please check out these other companies as well.

Low-Cost Portable Wi-Fi Routers

In most cases, a portable Wi-Fi router handling a large quantity of data will be more expensive than a SIM card. However, this is not always the case.

For instance, Ninja WiFi router costs 770 yen/day with 3 GB/day. Furthermore, there is a 20％ discount via MATCHA and costs 3,080 yen for 5 days , which is a similar fee to SIM cards.

While it may be burdensome to carry a router, it allows multiple devices to access the Internet with no need to change SIM cards.

Please consider these facts when considering a portable Wi-Fi router.

FAQs about SIM Cards in Japan

Q1. is a voice sim or data-only sim a better choice.

Voice SIM comes with a Japanese telephone number while data-only SIM does not.

With WhatsApp, Messenger, and LINE becoming popular messaging apps, some may wonder why you need a Japanese phone number if you're not a resident.

But a phone number has its advantages. Firstly, users can phone the police or fire department when trouble occurs. Emergency calls can be made in other languages besides Japanese, so this is a major feature.

To apply for various services in Japan, such as the popular electronic payment app Pay Pay, users must register a phone number.

Those who are interested should check mobal, which handles Voice SIM cards suitable for short-term trips.

Q2. What does "unlimited data" mean?

In regards to data traffic, some SIM cards offer "unlimited" data usage.

Most of these types will easily handle 2 to 3 GB per day. However, exceeding this capacity will cause the speed to be reduced. While Internet accessibility remains, the flow of data will be considerably slower.

Q3. Can I change the SIM card of my smartphone?

If your smartphone is SIM-locked, the answer is no. While there are SIM-free phones in most Asian countries, some Japanese and American phones are locked.

There is a way to open these types of phones. Ask your carrier for information on how to unlock your smartphone.

Additionally, please note that some SIM cards may not be compatible with certain smartphone models. There is a compatibility list on the official websites of SIM card providers, so be sure to take a look!

Q4. How should I handle my original SIM card?

If you are going to change the SIM card in your home country, store the original in a dust-free place.

Those who plan to replace the card in Japan should bring a SIM card case. It can be purchased on Amazon and other retailers.

7 Best SIM Cards for Japan in 2024

Home | Travel | Asia | 7 Best SIM Cards for Japan in 2024

If you want to have mobile data during your trip, consider getting a SIM card for Japan . There are several cards to choose from depending on the purpose of your trip, so I’ll share my top recommendations as well as their pros and cons.

I’ll tell you upfront that we use the Holafly eSIM card whenever we travel abroad, and the company even has eSIMs for Japan . We’ve never had a problem using Holafly, and what I like most about these digital cards is that they’re super easy to install and activate. Plus, the plans come with unlimited data for Japan , so we never have to worry about how much we’re using. You can even get a discount on Holafly for being a Capture the Atlas reader; just use our link.

5% OFF your international eSIM card

That said, if you prefer a physical SIM card for Japan or your phone isn’t compatible with eSIM technology , you can still get internet for travel . In this case, I recommend the Japanese SIM cards from SimOptions , which you can order online and have delivered to your home. Just be sure to order it in advance so you can install it before leaving for your trip.

There are other SIM card plans for Japan , so in this guide, I’ll share the best ones, where to buy them, and some tips for finding the most suitable options for your trip.

How do Japanese SIM cards work?

First of all, you should be aware that it’s against the law for tourists to have a phone number from Japan . In other words, you can’t get a SIM card in Japan that includes phone calls.

Fortunately, you can still get travel Internet in Japan thanks to Japanese data SIM cards that allow you to access the Web. In this way, you can make calls and send messages through a mobile app like Messenger, WhatsApp, or Skype.

When you’re choosing a travel SIM for Japan , always check your device’s compatibility and mobile network first. You don’t want to spend money on a card only to find out once you’re in Japan that you can’t use it with your phone.

If you decide to go with the Holafly eSIM for Japan , I recommend checking your device’s compatibility here . For local Japanese SIM cards , you can check this on the retailer’s website or at the storefront.

Japanese SIM card price comparison

I’m going to share the best SIM cards for Japan , but first, here is a brief overview of my top picks. This way, you can quickly compare the most important stats like price, duration, and amount of data.

You’ll see that Holafly offers the best deal for both short-term and long-term trips. Not only is Holafly affordable, but its cards come with unlimited data, so you can enjoy the Internet without worrying about your data usage. The digital SIM card is delivered via email, so you can purchase it before your trip or when you’re already in Japan.

Of course, I know that some people prefer a physical card, so I’ve included several Japanese SIM cards that you can insert directly into your device. The cheapest option is the Rakuten Mobile SIM, which you can buy from a local store in Japan. The downside of getting this card is that you’ll have to locate a store that sells Rakuten Mobile, and the live customer support is in Japanese, so if you have any issues, it could be hard to find a solution.

Personally, I prefer paying a little more for the eSIM from Holafly since the company offers live chat in English. When I need a physical SIM card, I go with SimOptions because I can order it before my trip, install it, and fix any issues I may have prior to landing in Japan.

What is the best SIM card for Japan?

For us, the best SIM card for traveling to Japan is the Holafly eSIM . It arrives by email as soon as we purchase it, so we can buy it whenever we want, plus it offers high-speed unlimited data.

I’ll tell you more about Holafly as well as the other top SIM cards for Japan below so you can make the best choice for your trip and preferences.

1. Holafly eSIM, the best SIM card for Japan with unlimited data

The Holafly eSIM for Japan is a digital SIM, so after you order your card , you’ll get an email with a QR code that you can scan to start accessing the Internet. This is ideal if your phone doesn’t have a dual card slot, or you are already abroad and need a SIM card.

Keep in mind that to scan the QR code, you’ll need to print it out or send it to your travel companion so you can scan it off their device. Also, I recommend checking your phone’s compatibility here before purchasing the international eSIM .

Looking at the Japanese eSIM card plans for Holafly, you’ll notice that each one includes unlimited data. The shorter-term plans are a bit more expensive compared to other local cards, but Holafly is more convenient, and you can snag a discount on your Holafly purchase by using our link.

2. SimOptions, another one of the best SIM cards for Japan

Another one of the best data SIM cards for Japan is the physical one from SimOptions . I like using SimOptions because I can order the SIM card ahead of time and sort out any issues before my trip. It takes 1-3 business days for the card to arrive at your home, so make sure you order it in advance.

Something else I like about using SimOptions is that I don’t have to waste time and go searching for a local SIM card in Japan once I land. Instead, I can connect to the Internet right away and enjoy the rest of my trip. Also, if your device has a dual SIM card slot, you can simply insert the Japanese SIM card without having to remove your regular card.

SimOptions offers customer support by email and live chat in English, and there are different plans to choose from depending on the length of your trip. The plans have varying amounts of data, so here is a breakdown of the prices:

3. SoftBank SIM, another Japanese SIM card with data

The Japanese SIM card from Softbank is a physical SIM from one of the largest and most prominent communications companies in the country. It’s super popular, so you’ll be able to find it at official retailers, shopping malls, and even supermarkets.

Softbank has 400,000 Wi-Fi points throughout Japan, so you can access the network during your trip for free. Keep in mind that, if you use up the first megabyte of your plan, you can only recharge the card for 14 days afterward. I don’t really see the point of this, but it’s something to consider if you’re using data to work remotely.

Another disadvantage of this card is that you only get 500 MB for 31 days. This is equivalent to about two or three days of navigation, so it’s not a lot of mobile data.

Even so, this is a common prepaid SIM card for Japan , so if you decide to get it, you can purchase it online. You’ll have to register on the website by uploading a photo of your passport and providing some basic personal information.

4. IIJmio, an alternative SIM card for Japan

IIJmio is another option to consider if you’re looking for a local Japanese SIM card . It offers basic mobile data plans for 30 days, and while you’ll only get a few gigabytes, it should be enough for occasional Internet use and Google Maps.

One drawback of this card is that once the data is used up, you can’t recharge it. Rather, you’ll have to buy another prepaid Japanese SIM card . On the other hand, IIJmio offers customer support in Japanese and English, and you’ll receive an origami set with instructions as a gift with your purchase.

5. B-mobile, a popular Japanese SIM card for tourists

If you want to buy a Japanese SIM card online , check out B-mobile . With this service, you can order a SIM online, then pick it up once you land at the airport in Japan. B-mobile can even deliver the card to your hotel.

Regarding its mobile data and network, B-mobile has great coverage throughout the country, so it’s quite convenient for traveling tourists. Also, if you need to extend the duration of your plan or add more data, you can do so without having to buy another SIM card.

Overall, this is a flexible option, although you should keep in mind that B-mobile’s SIM card plans for Japan last from 10 to 20 days and don’t offer unlimited data. So, I only recommend B-mobile if you’re traveling short-term and don’t need too much mobile data.

6. Rakuten Mobile, a good Japanese SIM card for travel

Rakuten Mobile is another company with local SIM cards in Japan . Its 30-day plans offer basic, moderate, and unlimited data consumption, so you should find an option that suits you.

In fact, if you plan on spending a month in Japan, Rakuten Mobile is the cheapest Japanese SIM card , particularly for unlimited data. However, the Internet speed isn’t super strong, so that’s something to consider.

You can buy this SIM card in Japanese shopping malls, as well as in many stores and the airport. Activating it is simple since you just have to insert the SIM into your device to connect to the Internet. Your purchase also includes a free Rakuten Mobile email domain (@rakumail.jp).

7. Sakura Mobile, another SIM card in Japan with unlimited data

The last Japanese SIM card that I recommend is the Sakura Mobile card. This local SIM offers some of the cheapest data plans in the country, and it has customer support in English. Overall, it’s a simple and practical option for those looking for a physical SIM card.

Another benefit of Sakura Mobile is that you can order your card online and pick it up at the airport once you land in Japan. If you’re already in the country, you can purchase it at any official Sakura Mobile store. The only potential issues are that you must unlock your device and check its compatibility with the network here .

Where to buy a SIM card for Japan

Depending on which option you choose, you can buy a Japanese SIM card from the U.S. or from Japan. Personally, I prefer buying mine before the trip, so I feel fully prepared, but there is nothing wrong with purchasing a local SIM at a store or airport in Japan.

Again, we always buy the Holafly eSIM in advance through its website . Then, all we have to do is open our email and scan the QR code. When we need a physical SIM, we order it online through SimOptions, allowing 1-3 business days for it to arrive at our home.

Both of these SIM cards for Japan are easy to install and will allow you to travel with total peace of mind, and with support in your language.

Buy a SIM card in Japan upon arrival

Don’t worry if you’re already traveling or have landed in Japan. You can still get an eSIM for Japan with Holafly , although I recommend checking your device’s compatibility here first. There is also the option of getting a local Japanese SIM card , like the ones I mentioned above. You can find them at several stores, supermarkets, train stations, and airports in Japan.

Just remember that if you opt for a local SIM card, you’ll have to locate a store or retailer, which could take some time. Also, depending on the company, customer support may only be available in Japanese.

Most local cards don’t have unlimited data, so if this is something that’s important to you, I highly recommend getting the Holafly eSIM . Holafly’s Japanese plans range from short-term visits to stays as long as 90 days, and they all have unlimited high-speed data. The closest local competitor is Rakuten Mobile, which has a 30-day plan, unlimited data options, and good rates. However, some travelers have told us that after a few days, the Internet speed slows down significantly.

How to activate a Japanese SIM card for travel

Activating an eSIM or SIM card for travel to Japan is simple. With the Holafly eSIM , just scan the QR code in your email. You’ll have to print it out or send it to a travel companion to scan it.

For any physical SIM card in Japan , insert it into your device and activate the data. You’ll automatically receive an auto-configuration text message letting you know it’s ready to use.

Japanese SIM card compatibility and requirements

To wrap up, I’ll reiterate that we love using the Holafly eSIM for Japan or any other trip abroad. If your phone is unlocked and you’ve confirmed here that it’s compatible, I highly recommend it.

Otherwise, there are several other physical SIM cards for travelers that will let you access the Internet in Japan . Hopefully, after comparing the different plans, you’ll find a suitable option that allows you to browse the Web, do Internet searches, and send messages.

If you have any questions about these prepaid SIM cards for Japan , or you’d like to share your experience, please let me know in the comments below. I’d love to hear from you!

Have a great time in Japan!

Hi Ascen Aynat,

How is the connection in rural areas in Japan? I’ll be traveling to Kyushu, Shikoku and Hokkaido and will do quite a bit of hiking and therefore away from urban areas. And in that respect is one option (holafly versus a simcard bought in Japan) better than the other?

Hi Yolanda, The connection in rural Japan is actually pretty good compared to other countries. In my experience, Holafly has always come through with a stable connection, even when we’re hiking or travelling in remote areas.

I’m going to Japan next week and will be there for 10 days. If I get a SIM card for 30 days, can my wife use the same SIM card when she going to Japan in a week after I get back? Or are the cards dedicated to one cell phone when activated? Thanks, Jason

Hi Jason, It depends on the card since some allow data sharing, while others are only for one specific device. Of course, take into account how much data each card includes since if you share it, you’ll run out of data faster. In other words, it could be more cost-effective to purchase separate SIM cards for Japan.

Japan Here We Come

The Best SIM Cards for travel to Japan

Here we share the best tourist SIM cards to stay connected in Japan.

We have traveled through the country many times. The very first time we often found a “Handy” phone in our hotel room. A telephone that you could use during your stay. But that time is over.

You now have to find a solution yourself if you want to be connected. And that is really recommended. Although there is free internet in quite a few places, and even apps that make it easy to connect to free WiFi hotspots, there are still many places where you will have to have a data subscription if you want to use the internet.

And we always use the internet a lot while in Japan.  We use our smartphones to navigate the vast cities, to find recommended places to eat and cat cafés, and to look up the train and metro schedules.

We also like to browse around the shops where you can find gadgets and care products that we don’t know about. But also there we often have to fall back on our smartphones to discover what it is exactly or how it works.

Roaming tariffs can be insane, they certainly are in our case, and local SIMs aren’t expensive at all.

Below is an overview of the physical SIMs that you can order online and pick up at the airport, eSIMs, and other ways to stay connected in Japan.

We have already used both a physical SIM and an e-SIM, so we also explain how this works.

Don’t worry if you’re reading this article on the day of departure or when you’re already in Japan.  You can also buy a SIM at the airport or in an electronics store in Japan.  I will guide you on how to do this further down in this article.

And, if your phone supports it, you can of course opt for an eSIM at any time.

Regular Japan Traveler SIM vs eSIM

During our first trips we always used a regular SIM that we pre-ordered online and picked up at the airport upon arrival. Very convenient and everything always went very smoothly. Below we explain in more detail how this works.

However, we both recently switched to a cell phone that supports eSIMs and thus we used an eSIM for our last trip.

It was the very first time we used such an eSIM, so we were a little nervous about whether everything would run smoothly and the technology would not let us down.

That stress seemed completely unwarranted. All steps on how to install and activate the SIM were neatly explained.

What’s our verdict?

Both worked equally well when considering connectivity and speed. If your phone supports eSIMs, I would opt for an eSIM for Japan. It offers the advantage that you do not have to change SIM cards and that you can, at all times, easily switch from your regular SIM to the Japan tourist eSIM.

We like the Airalo’s eSIMs for their ease of installation and Mobal eSIMs for Japan for their excellent selection of data packages.

We have a full guide on eSIMs for Japan .

But no problem if your phone does not support eSIMs. There are plenty of alternatives that you can order online and quickly pick up at the airport upon arrival. Below is an overview.

Japan Tourist SIM cards – The top choices

The list of Japan traveler SIM cards seems endless. We found no less than 30 different options when we were looking to buy a SIM for our last trip.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

Below is an overview of our top picks.

Buying a SIM card in Japan

If you’re already in Japan when you’re reading this there’s no need to worry. 

Believe it or not, we arrived unprepared the very first time ourselves. It’s relatively easy to buy a SIM card in Japan. We then bought an IIJmio SIM in a Ydodobashi Camera store.

Here are your options for when you’re in Japan.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport (see here and here ).  You can also find SIM cards in the BlueSky shops .

The sales points from the operators will likely be able to better assist you in English and may give better advice. 

In the cities

Another option to buy a SIM card in Japan is to head to one of the BIC Camera or Yodobashi Camera stores. 

They sell various prepaid SIM cards for Japan tourists.  We used the IIJmio SIM during our very first trip to the country. This SIM comes with a brief explanation of how to install it. You can also find all the settings on their website.

The data limit of 1GB is pretty limited but you can buy coupons to recharge the SIM.

Usually, at least some of the staff will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they do at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is.

But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

There are several Yodobashi and BIC Camera stores. At your hotel they should be able to give directions to the nearest one or you can use Google maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend. They have so many electronic gadgets and gizmos in Japan, all things that you won’t find elsewhere. (I still don’t understand why those luxury toilets can hardly be found anywhere else in the world)

But you can also compare the various options from the comfort of your hotel room and order a SIM online. 

An eSIM is the first thing that comes to mind. You can compare the alternatives, buy the one that suits you and install and activate it. All in a matter of minutes.

If your phone doesn’t support eSIMs you can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

Alternative options to stay connected

You don’t want the hassle of changing SIM cards? No problem, in that case you can opt for one of the following alternatives.

Free WiFi in Japan

A lot of places offer free WiFi. You find it in coffee shops (Starbucks) Metro Stations (Tokyo Metro) and JR train stations.

It used to be quite a hassle to repeatedly connect to these networks but there is now an app, Japan WiFi Auto-Connect , that will automatically connect to certain public WiFi hotspots. For security reasons not to all public WiFi hotspots, but only those managed by trusted corporations or public authorities.

It worked perfect for 90% of the time during our last trips. When I walked into a metro station or train station I was usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple.

Thanks to this app, among other things, it has become much easier to make use of free WiFi hotspots.

During our first trips to Japan, we had to fill out a form each time we wanted to use a hot spot, only to realize that the WiFi didn’t work in the end. Now, free WiFi is much more reliable for foreigners.

However, I recommend not relying solely on it, just as we don’t. Hotspots become scarcer as you leave the major cities. Even in the capital, I find it convenient to have internet access at all times and be able to look something up when it crosses my mind, not just when I’m at a hotspot.

It’s a matter of convenience, but for the small price of a SIM card, I think it’s worth it.

Here’s an overview of the WiFi hotspots in Tokyo .

Pocket WiFi Devices

The main advantage of using a pocket WiFi device is that you don’t need to switch the SIM in your phone. You also don’t need to change any of the settings of your phone. You only need to connect to the WiFi signal broadcasted by your WiFi Device.

Do make sure that your data connection is disabled to avoid any nasty data roaming fees.

And if you’re traveling with your family, or with friends, you can all share the same WiFi signal.

As your SIM remains in your phone this also means that friends, family, work relations, and anybody else who has your phone number can reach you as if you were home.

A disadvantage of a pocket WiFi device is that it is one extra device that you need to carry around and that you will need to charge on a daily basis if you use it frequently.

If your phone supports eSIMs , we think that is the ideal solution. Since we got our new phone, with support for eSIM, we have always opted for an eSIM.

Your regular SIM remains in the phone. You will remain reachable on the known number and you can use data via your local eSIM. So the best of both worlds.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. It used to be a virtual operator but it is now building out its own network. Today it covers about 94% of the population. Their customer relations team only speaks Japanese.

There are several other providers but these typically piggyback on the network of these 3 majors to offer their services.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second, they are not far behind, and they still cover 99% of Japan (population-based).

Au by KDDI is seen as the least reliable network of the major players.  They do well in terms of coverage but their reception is not as good inside buildings or underground due to the frequencies they’re using.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There are many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

Enjoy Japan!

Japan SIM Cards: Your Must-Read Guide to Staying Connected in Japan

Plus, the 10 reasons why a Japan SIM Card is your best option!

If you're going to Japan & want to stay connected you'll need to make a decision: Japan SIM Cards, Wi-Fi routers, Roaming & Free Wi-Fi are all options to keep you connected in theory - but which option is best for you and do you really need a SIM Card for Japan? We've done the hard work for you with an ABC Guide on how to get connected in Japan, including some common misconceptions...

A. Free Wi-Fi is not a thing!

Japan has a reputation for being super-advanced but in some areas change has been slow. Surprisingly, free internet is almost impossible to find throughout Japan - even in Tokyo. Most Wi-Fi hotspots are not free & require you to register each use. The free ones aren't exactly free either as they're in cafes & restaurants - so you'll need to pay for food or drinks to connect. If you plan to be on the move rule this option out!

B. Renting a Wi-Fi Router may not make sense!

If you plan a very short stay and are happy to pay daily rental fees, then a Wi-Fi router may be your best option. Remember though that you'll have the hassle of keeping an extra device charged and returning your rental kit to the airport at the end of your trip. An easier and more economical alternative is to buy a data-only SIM. Unlimited Data SIMs are available from 8 to 31 days duration (see: www.mobal.com ) giving you the option to use the SIM in your own device and dispose of it at the end of your trip. You can even use tethering too to connect other devices. Get your SIM delivered to you before you travel so that you can Instagram from the plane on touchdown - or pick-up from the airport when you arrive.

C. Roaming is tricky.

Most cellular providers offer roaming in Japan, but beware - just using your phone for even a short period can result in returning home to bill shock! Some providers such as T-Mobile USA appear to offer great deals with unlimited data in Japan for no extra charge. Note though that data speeds are heavily throttled so this may restrict how you use your phone.

The advice is when in Rome... Get a local Japan SIM and avail of high-speed data and cheap calls if needed. The Japan Unlimited SIM from Mobal gives you data, voice & text with a minimum of 7GB of 4G LTE data per month (larger plans available if needed). If you use more than your high speed data allowance, your data will slow down, but the amount you can use is unlimited - plus, you can buy more high speed data if you need it. You get to control how much data you use, so you'll never return home to bill shock and you'll never run out of data either.

10 Reasons Why a Japan SIM Card is your Best Option

Until recently buying a Japan SIM card for your smartphone was simply not an option for overseas visitors - unless you wanted to sign-up to a complicated 2-year contract with huge fees payable if you left Japan early.

Luckily you can now get a no-contract voice & data SIM as well as prepaid data SIMs - all with English customer service, free incoming calls & free domestic calls on the same network*.

Order online from Mobal and you can choose to have your Japan SIM Card delivered in advance or collect from main airports & cities in Japan on arrival.

If you're still not convinced here's 10 more reasons why you absolutely need a SIM Card for your phone when in Japan!

1. Google Maps

2. phone numbers have status.

Japan is slow to change - think fax machines, single-glazed windows & CDs (yes, really!). If you plan to live in Japan a phone number is a must - you need one to get a job, rent an apartment, open a bank account, ship/receive a package - you basically need a phone number to do just about anything!

For visitors booking hotels and restaurants, a Japanese phone number can often be more acceptable than your credit card, so consider the advantages of a voice and data SIM over a data-only SIM.

3. Shopping Online?

Planning to avail of free delivery to your address when in Japan. Great deals are available from electronics stores such as Bic Camera or clothing outlets like Muji but guess what you need to avail of delivery? A Japanese phone number!

4. Uber/Japan Taxi

If you find yourself out at night (a spontaneous Karaoke night perhaps!) you'll quickly discover public transport isn't 24 hour. If you need an English-speaking driver Uber is useful and Uber taxis don't charge a late-night surcharge - great for getting back home from wherever you are.

5. Eating In is the New Eating Out

Want to order takeout to your room - all from the comfort of your phone? You definitely need a SIM and you may even need a phone number. We recommend you go for the Mayo-Jaga pizza (potato & baked mayonnaise on a tomato base)!

6. Google Translate

Whether it's deciphering zany pizza menus for home delivery or communicating with the locals you will definitely make use of this app. As it doesn't work on batteries we definitely recommend you get a SIM card ;-)

7. Social Media

Being in Japan means lots of photos. Lots of photos means lots of sharing online. Make sure your family and friends are as jealous as possible of your adventures in Japan by keeping them updated through social media! Plus, with average commute times in Japan over an hour you'll end up browsing or wanting to!

8. Music/Podcast/Shazam

Walking through the streets of Japan and hear a song that catches your ear? Don't worry about having to figure out the Japanese to type in lyrics to Google - just use Shazam to find out and discover many new Japanese songs!

9. 4G or LTE speeds

As long as you're on a Japanese network and not an MVNO SIM you'll get the same data speeds as Japanese people do. It's fast as you might expect. Mobal's Japan Unlimited SIM is the only voice & data SIM available to everyone that uses the Softbank network - if you want quality this gets our vote.

10. Emergencies

With extreme weather events & earthquakes a part of daily life having a voice SIM with SMS capability doesn't just mean your analog friends can keep in contact from overseas, it also means you'll receive early warning alerts & updates.

Finally, here are 10 reasons why you should choose Mobal...

SIM Cards in Japan: How & Where to Purchase Them — And Best Alternatives in 2024

Monito's Managing Editor, Byron has spent several years writing extensively about financial- and migration-related topics.

Regardless of whether you're visiting Japan to soak in the warm waters of an onsen hot spring bath or admire the fleeting landscapes from the comfort of a bullet train, you'll probably be wondering how to connect your smartphone to the internet as soon as possible after you arrive.

That's where getting a local SIM card comes into the picture. Fortunately for you, in most cases, finding and purchasing a Japanese SIM card should be a breeze, and in this short guide, we show you the two major ways in which you can get the job done affordably and effortlessly!

Facts About SIM Cards in Japan

• Local SIM cards in Japan are widely available, even for tourists. However, at tourist locations such as airports, you can expect to pay a surcharge.
• We recommend opting for an eSIM instead of a local SIM card. eSIMs can be purchased and installed at home before you leave for Japan, giving you mobile data from the moment you arrive in the country.
• Airalo is a market-leading eSIM provider known for its attractive per-gigabyte rates. The cheapest eSIM bundle to Japan costs just $4.50 and gives you a speedy and reliable connection via local networks like KDDI and Softbank.

How To Get a SIM Card in Japan

If you're planning your trip to Japan, it shouldn't be a surprise to learn that you won't be able to call, text, or access the web on the go with your smartphone as you usually would at home. And if you do manage to get connected via roaming, it can result in hefty additional charges. That's where SIM cards come into the picture. By getting yourself a local Japanese SIM card (or, as we'll see, a digital eSIM), you'll be able to connect to the internet via mobile data while on the move and, depending on the bundle you choose, even send SMSes or make local phone calls.

To get a SIM card in Japan, you basically have two options:

Option 1: Local Physical SIM Cards

Buying a local SIM card in Japan works in much the same way as buying a SIM card does in your home country : you purchase a small microchip with a fixed prepaid amount of data loaded onto it for a once-off fee. (Especially as a tourist visiting the country for a shorter period, you probably won't need a recurring monthly contract or a more advanced bundle with additional minutes or text, but the option is normally available too, if you like.) You then insert this chip into your smartphone — and away you go!

These physical SIM card microchips come in three main sizes:

• Standard SIM: 25x15mm (about the size of a standard postage stamp)
• Micro SIM: 15x12mm (a bit smaller than a dime)
• Nano SIM: 12.3x8.8mm (about the size of a peanut)

The image below illustrates the differences in size, with the three smaller SIM cards on the right side representing standard, micro, and nano SIMs respectively, and the larger SIM card on the left (known as 1FF) no longer being used these days:

Most SIM card retailers offer only nano SIMs these days, including in Japan. But if the retailer you visit doesn't offer nano SIMs (or in case the SIM cards sold don't fit into your phone), you can ask for a SIM card adapter, which is normally very cheap and available in most cell phone shops or kiosks.

If you run out of data, you can normally recharge your SIM with ease, too. To do this, visit your network provider's website or go to the counter of pretty much any cell phone shop, convenience store, kiosk, or tourist information in Japan and ask about data recharge. Many Japanese retailers countrywide offer data packages for major networks like KDDI and Softbank, making it a quick and accessible option.

If you don't plan on using your Japanese SIM for a future vacation after you arrive home, make sure you cut your SIM card chip in two with a sturdy pair of scissors to prevent fraudsters from pulling any personal data from your card, and, if possible, recycle it with other electronic waste.

Option 2: eSIM Cards

A digital alternative to physical SIM cards, eSIMs are regular SIM cards that don't require inserting an actual microchip  into your device while providing the exact same benefits. Newer smartphones (but also smartwatches, tablets, and other devices) can be equipped with eSIMs, and since you don't need a physical microchip to install an eSIM, you can also get one before you even take off on your trip to Japan. To do this, you just need to visit an online eSIM service, purchase the eSIM you want, and follow the instructions to download and install it onto your device.

Like regular SIM cards, prepaid eSIMs come bundled with a certain fixed amount of data (or, more rarely, SMSes or telephone minutes) which you can use at your leisure while traveling in Japan. You get to choose the package you want, and you can generally also extend your eSIM's validity easily right from an app.

In general, eSIMs cost about the same as physical Japanese SIMs or are slightly more expensive per gigabyte, but in our opinion, their accessibility and eco-friendliness make them the better option for most travelers. We delve into why a bit later in this article.

Network Providers in Japan

Whether you use a physical SIM or eSIM, it's good to keep in mind that Japanese telecommunications are dominated by a handful of network operators. These networks provide the infrastructure that allows you to use mobile data on the go. In Japan, the biggest players are listed below, so be on the lookout for their names on storefronts (if you're looking for a physical SIM card) or on the top right-hand corner of your smartphone (which shows you which network you're currently connected to):

• and others...

In general, network connectivity for mobile data in Japan is outstanding , meaning that you won't have any issues accessing the web from any of the local networks, even in more rural or mountainous areas of the country.

Where to Buy a SIM Card in Japanese Cities

In general, it's very easy to buy a Japanese SIM card. Normally, you can buy a SIM once you arrive at the airport, but you can typically also do so at shops, convenience stores, and kiosks in city centres, malls, or business or market districts. (Don't forget that SIM cards aren't only sold in brick-and-mortar outlets and sometimes in pop-up booths or temporary stalls, depending on where you are.)

In Japan, you'll easily find SIM card dealers in the following locations:

• Haneda Airport (Tokyo),
• Fukuoka Airport (Fukuoka),
• New Chitose Airport (Sapporo),
• City centres (e.g. Tokyo, Kyoto, Osaka, etc.).

Digital eSIMs: A Better Option in Japan

As we saw earlier, eSIMs generally have numerous advantages and are often a better alternative to using a regular SIM card for most tourists. In our opinion, the most significant advantages include:

• internet immediately upon arrival in Japan,
• no negotiating with SIM card sellers at the airport,
• transparent and fair pricing,
• online extension is often possible,
• credit card payment is possible,
• local telecom provider networks are used.

However, there is one potential issue around compatibility. Not all devices support eSIMs. If your device was released before late 2019, we recommend double-checking on the internet or contacting a representative from an eSIM service to confirm whether your device is compatible before you purchase an eSIM. In general, the following devices will support eSIMs though:

Airalo  is an excellent eSIM provider for Japan . Its online platform offers global access to eSIMs through collaboration with big local telecom providers. In Japan, for example, Airalo works directly with KDDI and Softbank to provide you with high-speed coverage directly from their networks, wherever you are in the country.

Once-off prices for eSIMs for Japan range from $4.50 to $26 and include between 1GB and 20GB of data. Most travellers should be able to get by with these amounts without any problems.

We recommend Airalo in general, and especially if you travel often, the service provides an excellent connectivity companion while you're abroad.

• It is not compatible with every mobile phone
• Services usually don’t do refunds if you’re mobile phone happens to not be compatible

5 Best SIM Card services in Japan

Here are 5 of the most popular SIM Card services that you will be able to find for your Japan trip.

Mobal is a MVNO(Mobile Virtual Network Operator) that offers unlimited data cards for 8 days, 16 days, and 31 days. They offer free shipping to most countries in the world as well as various pickup locations within Japan.

The biggest appealing point about mobal’s SIM Cards is that they offer both “data-only SIM” and “data+voice+sms SIM”. The latter one is more expensive, of course, but if being able to use the phone is a priority for you, this is your pick.

2. Japan Wireless

Japan Wireless offers fixed data limit cards but at a relatively cheaper price. The prepaid SIM Card that they offer is for either 7 days, 15 days, or 30 days with a data amount of 500 MB/day.

Although they don’t offer international shipping, they can send the SIM Card to the airport of your arrival, the hotel where you’re staying, or the nearest post office from you. They also provide support via phone and email, both in English.

3. Simcard Geek

Simcard Geek offers both unlimited data cards and cards with a fixed data limit. Fixed data limit cards are slightly cheaper than unlimited data cards, so if you’re planning on not using the internet a lot, then this might be a good choice for you.

Simcard Geek also provides free worldwide shipping, but depending on the shipping location, it may take between 5 to 12 days in reaching you. So you will need to make the order quite in advance.

4. Japan Travel SIM (IIJmio)

Japan Travel SIM does not have an official website where you can pre-order. But instead, you will find this SIM Card in most electronic shops across Japan. So if you rather go to a shop after getting to Japan to purchase your SIM Card, then this is your choice.

You can also find this SIM Card at Amazon.com, so it is also possible to get it before your trip to Japan.

They offer fixed data limit cards (1GB/30 days, 2GB/90 days) but are rechargeable within the validity period.

Official Website:  https://t.iijmio.jp/en/index.html

5. U-mobile SIM

U-mobile SIM provides data-only SIM cards with a fixed data limit. The prepaid SIM Card that they offer is for either 7 days or 15 days, with a data amount of 220MB/day. This 220MB is high-speed data and if you pass this data amount, your connection speed will fall to 200kbps.

U-mobile SIM is available at the shop counters in the major airports in Japan. You can also find them at Narita airport’s SIM vending machines. Although they don’t provide support and data amount is limited, it is by far the cheapest option.

How to Buy SIM Cards in Japan

There are several ways you can purchase a prepaid SIM Card.

• At the airport: There are shop counters at the major airports in Japan. But be aware that these counters are not opened 24 hours. You can also find SIM Card vending machines at Narita Airport, although they are charged with a surcharge.
• At electronic shops:  SIM Cards can be purchased pretty much at any electronic shop in Japan. If you’re in Tokyo, you shouldn’t have any problem finding a shop where they have prepaid SIM Cards. The largest electronic shops are “Bic Camera”, “Yodobashi Camera”, and “Yamada Denki”.
• Online: Many MVNOs have their own website where you can preorder your SIM Card before coming to Japan. Some services have international free shipping, some have specific points of pick-up such as airports, and others will send it to the hotel where you’re staying. Other than MVNOs, you can also find online travel agencies that offer this service such as Klook. Amazon.com also has SIM Cards that you can buy before your trip.

Some WiFi rental services will also have the option to provide a prepaid SIM Card if that’s the option you want to go with. At Japan Wireless, you can purchase a SIM Card from their website.

Which is Better in Japan, SIM Card or Pocket WiFi

Another thing I would like to suggest is to rent a pocket WiFi. You can rent a Pocket WiFi online just the same as you would a SIM Card, and pick it up at the airport of your arrival or the hotel you’re staying at.

Here is a chart comparing SIM Card purchasing vs Pocket WiFi rental.

• Speed: Both, SIM Card and Pocket WiFi have a high-speed internet connection, even though when it comes to the SIM Card there is usually a daily limit of high-speed connection.
• Coverage: Again, both options have a wide coverage when it comes to internet connection.
• Cost: Although the pocket WiFi rental isn’t that expensive to begin with, it is usually cheaper to buy a SIM Card.
• Practicality: The SIM Card is more practical in the sense that you don’t need to carry around an extra device and worry about the remaining battery amount. Also, in the case of the pocket WiFi rental, it is necessary to return the device (even though not complicated), which is something you don’t need to worry about in the case of a SIM Card.
• Multi-device: The biggest weakness of the SIM Card is the fact that you can use the internet connection only for one device. On the other hand, the pocket WiFi is able to connect multiple devices at once.
• Heavy using: Prepaid SIM Cards tend to have a daily limit amount of high-speed data, and afterwords the connection slows down. Some pocket WiFi also have this problem, but there are also some pocket WiFi rental services that provide unlimited high-speed internet connection.
• Compatibility: If you’ve never used a SIM Card before, then this might be your biggest concern. First, you need to make sure that the mobile phone you’re taking to Japan is unlocked. After that, you need to make sure the SIM Card you’re purchasing is compatible with your mobile phone. This is a concern you won’t have in the case of a pocket WiFi device.

FAQ about SIM Cards in Japan

Q1. How can I install and activate the prepaid SIM card?

This actually depends on the service you’re using. Most SIM Cards are as simple as inserting it into your mobile phone and following the instructions. Sometimes a brief registration process is required in order to proceed, but most times you don’t have to do that.

Q2. How can I know if my mobile phone is compatible with a SIM card?

First, you have to make sure that your mobile phone is unlocked or is a SIMfree mobile phone. If your mobile phone is locked, that means you can’t use the network of carriers other than yours.

Another thing that you need to know is the size of your SIM card. Most SIM card services provide all sizes, but sometimes that is not the case. So be sure to ask before purchasing.

If your mobile phone is relatively new, you have a good chance that you won’t have compatibility problems. But just to make sure, you can search the compatibility of your mobile phone by visiting the “willmyphonework” website.

Willmyphonework Website: https://willmyphonework.net/

Another thing you can do is just ask your mobile phone provider if it’ll be compatible.

Q3. What other alternatives are there to connect to the internet in Japan?

Other than purchasing a prepaid SIM Card and renting a pocket WiFi, there are many other ways you can get access to the internet.

First, there is the Free WiFi That many companies provide. You can find it in airports, train stations, hotels, and some cafes. There are also services where you can rent an entire phone with data included. There is also the option of international roaming which you would have to discuss with your phone provider.

An unconventional way would also be to go to an Internet Cafe. But that would be inconvenient unless you are interested in the experience itself.

As you can see from the previous comparison chart, both the SIM Card and the pocket WiFi have their own strengths and weaknesses.

Prepaid SIM Cards are practical in the sense that you don’t need to carry an extra device, you don’t need to return anything at the end of your journey, and the setting is fairly easy as long as it is compatible.

On the other hand, the pocket WiFi is good for multiple device connectivity and heavy internet usage. You also don’t need to worry about device compatibility.

Personally, I would recommend renting a pocket WiFi. If you’re traveling in a group, it would be cheaper to rent a pocket WiFi as opposed to buying several SIM Cards. Even if you’re traveling alone, it is most possible you’ll have more than one device you’d like to connect to the internet. Plus, the pocket WiFi device is not bulky so it won’t be much of a bother, and returning the device is as easy as putting the set in any postbox in the country.

Now that I have recommended you to rent a pocket WiFi, the next question would be: where can you get a pocket WiFi device?

Usually, you can order one online and the device will be sent to either the airport of your arrival or the hotel you’re staying at for you to pick up.

There are many companies that offer pocket WiFi rental services. Here is an article where I compared some of the most popular pocket WiFi rental companies. I also provide discount coupons at the moment, so don’t miss this chance.

Born and raised in Costa Rica, I started living in Tokyo from college. I love traveling within Japan & around the world. Since I wasn’t born in Japan, I know the cultural impact that you can get when visiting Japan for the first time and what you might be worried about before your trip. And I’ve lived long enough to somewhat understand the nuances of the Japanese culture that make this country such an attractive place to visit. Hopefully I can provide to you both the information you’re looking for and the information you didn’t know you needed to know.

Japan SIM Cards: Everything You Need To Know

by Melissa Giroux | Last updated Dec 3, 2023 | Asia , Japan , SIM Cards , Travel Tips

Visiting Japan soon? Make sure to know what to expect when it comes to purchasing a Japan SIM card .

Fortunately, Asia is one of the best places where you can buy a SIM card easily. You should be able to find a cheap SIM card pretty much anywhere in Asia. In fact, most data packages are affordable, which makes the whole thing easier!

In this guide, we’ll explain where to buy a SIM card in Japan in person and online. We’ll also discuss prepaid SIM cards and eSIMs if your mobile supports them.

Before you read this guide, you may wonder if you actually need a SIM card in Japan. If you don’t mind not having Internet, you’ll likely find free Wifi in restaurants, shopping malls, and hotels.

That said, if you need data to get around, call a cab, or translate Japanese – you may want to get a SIM card for your travels in Japan.

Best SIM Cards In Japan

If you’re traveling in Japan, we recommend using a SIM card from Mobal, SoftBank, B-mobile, or Airalo. (I’ll get back to Airalo later on, so keep reading to learn more!)

That said, if you’re planning on visiting other countries during your trip to Asia, you might want to make sure to pick an option that offers coverage in other Asian countries.

How To Buy A SIM Card In Japan

You can either buy a Japanese prepaid SIM card in person in some international airports, mobile provider stores, convenience stores, or online.

Usually, you can expect higher costs and low data offers at the airport, so we don’t recommend buying a SIM card at the airport.

That said, you won’t necessarily find SIM card shops in every airport, so it’s essential to keep this in mind. And, when you see a shop, you might also have limited options.

For this reason, I’d recommend buying a SIM card directly from the mobile provider store. Note that you may need your passport to buy one.

Although, this means you won’t get data right upon your arrival. So, if you prefer to be connected at all times, you could use an eSIM or purchase an Asia prepaid SIM card online.

Now, let’s take a look at the data plans offered by Mobal, SoftBank, and B-mobile.

Planning your upcoming adventures? Travel by bus! (It's cheap!)

Mobal SIM Cards

Mobal offers several different tourist plans:

• Unlimited data, valid for 8 days for JPY 3,990 ($26.62)
• Unlimited data, valid for 16 days for JPY 5,990 ($39.96)
• Unlimited data, valid for 31 days for JPY 7,490 ($49.07)
• Unlimited data, valid for 30 days for JPY 7,500 ($50.04)
• Unlimited data, valid for 60 days for JPY 12,000 ($80.06)
• Unlimited data, valid for 90 days for JPY 16,500 ($110.08)

SoftBank SIM Cards

Softbank offers a prepaid SIM for travelers, which includes:

• 3 GB data, valid for 31 days for JPY 1,650 ($11.01)

B-mobile SIM Cards

B-mobile offers two SIM-only plans for tourists:

• 5 GB, 10 days, JPY 1,980
• 7 GB, 21 days, JPY 2,970

Overall, we think Mobal is the best option if you plan to buy your SIM card in person. That said, any would do if you can’t find their store!

How To Buy A Japan Prepaid SIM Card Online

If you wish to have your SIM card ready for your arrival, you could purchase it online or on websites like Amazon.

You’ll find different plans on Amazon. For example, the Prepaid Asia-Pacific SIM Card works in more than 17 countries and gives you unlimited data for 14 days. Japan is included.

But there are many other options worth considering, so have a look and make sure the countries you plan on visiting are listed.

Browse your options on Amazon

Another option is to purchase a prepaid Asian SIM card on SimOptions .

They currently offer two data plans in Japan:

• 10 GB, valid for 30 days for $24.90
• 10 GB, valid for 14 days for $49.90

• 10 GB, valid for 15 days for $45.12
• 10 GB, valid for 30 days for $51.75

Browse your options on Jrailpass.com

Finally, the last option is to buy an eSIM card for Japan or, if you’re traveling to multiple countries, an eSIM plan for Asia.

How To Buy An eSIM Card For Japan

eSIM is a new concept that allows you to have a virtual SIM card inside your phone. If your mobile phone supports eSIM cards – it’s definitely one of the best options to get data in Japan.

I started using eSIM as soon as my mobile phone supported it. And I first tried it when visiting my family in Canada. To buy eSIMs, I usually use Airalo . Keep reading to learn more about the best eSIMs for Japan.

Airalo Japan

If you want to buy an eSIM for Japan, you could purchase one on Airalo .

This website offers many eSIM cards worldwide and special plans for Asia and Japan. I’ve been using Airalo for several months, and it works fine.

Here are the options available :

• Moshi Moshi: 1 GB, valid for 7 days for $4.50
• Moshi Moshi: 2 GB, valid for 15 days for $6.50
• Moshi Moshi: 3 GB, valid for 30 days for $8.50
• Moshi Moshi: 5 GB, valid for 30 days for $11.50
• Moshi Moshi: 10 GB, valid for 30 days for $18
• Moshi Moshi: 20 GB, valid for 30 days for $26

Here’s an overview of the options available for Asia :

• 5 GB, valid for 30 days for $20
• 10 GB, valid for 30 days for $37

The options mentioned above are part of Asialink and offer coverage in 14 countries, including Japan.

Alternatively, if you’re traveling in other countries that are not mentioned on the list, you can try Discover Global, which offers coverage in 87 countries, including Japan.

Here’s an overview of the options available on Discover Global :

• 5 GB, valid for 30 days for $35
• 10 GB, valid for 60 days for $59
• 20 GB, valid for 180 days for $89

Now, one important thing to note about Airalo is that you’ll need to keep an eye out for the provider in each country.

Suppose you ever have trouble connecting to the Internet during your trip. In that case, it might be because you’re connecting automatically to networks and need to select a network manually instead.

When you purchase the eSIM, you’ll get access to the list of networks supported in each country.

Final Thoughts On SIM Cards In Japan

As you can see, getting a prepaid SIM card in Japan or even an eSIM for your travels in Japan is pretty straightforward.

You’ll even be able to stay connected wherever you go in Asia without changing your SIM card, especially if you purchase an Asia plan.

I believe the eSIM card is the most convenient way to get data in Japan if you wish to have data upon your arrival. This way, you won’t need to go to a store to buy a SIM card.

Obviously, you need to make sure your mobile phone supports eSIM first.

Should I get a SIM Card when travelling to Japan? SIMカード

• Published on : 12/04/2023

Prepaid SIM cards allow for high-speed data usage during travels to Japan, but whether or not purchasing one is the best option for an upcoming trip depends on the individual. We'll compare a temporary Japanese SIM card to other popular options for staying connected. 

What is a Short-Term Japanese SIM Card? 

A Subscriber Identity Module (SIM) card is a standard part of any cellular mobile device and allows said device to connect to a network for usage. Oftentimes, visitors to Japan will look into purchasing a temporary SIM card for using international phone data prior to their trip. 

For using these SIM cards in Japan, one can choose the period of valid usage ( 8 days, 16 days, or 31 days ) and then have it sent to their delivery address in their home country prior to departing for their trip. After arriving in Japan, the SIM card can be inserted into their phone or device then configured using the directions found here . Simultaneously, SIM cards can be sent to a traveler's place of stay within Japan after they've arrived.

Be aware that only an unlocked phone  can use the Japanese SIM card, so be sure to check for phone compatibility prior to purchasing. Also note that the SIM card does not support access to phone calls or SNS messaging, but making calls through messenger applications like LINE (the most popular service in Japan), Whatsapp, or another service is possible and largely standard.

In order to assess if a SIM card is the best choice as an international traveler, we’ll compare using a SIM card to three of the most common alternatives; Data roaming with pre-existing phone plans, foregoing individual data and instead relying on free public WiFi , and renting a pocket WiFi device.

SIM card installation

SIM Card vs Data Roaming 

Data roaming is utilizing mobile data provided by a local cellular provider that has a contracted agreement with a provider back in a traveler’s home country.

Roaming varies by provider, individual plans, and the country of travel, so how the conditions of data roaming compare to that of a SIM card varies largely by individual tourists and their phone usage.  

However, in general, roaming entails additional fees added to the base contract costs. For travelers where this is the case, the SIM card may be an enticing option, as it is a prepaid expense with no extra hidden charges.

Data roaming notification

@flickr/ Kai Hendry

It’s important to note that oftentimes roaming charges are issued on a daily basis with limits set in place, meaning that expenses can stack up quite easily and unexpectedly. On average, U.S. cellular providers will charge anywhere from 10 to 30 USD per day for roaming data in Asia. Other companies may also price roaming on a per-megabyte basis. Through a Japanese SIM card, the unlimited data included in the base price allows for visitors to be connected at all times. 

For those with adequate roaming options already included in their phone plans there will be no issue. However a prepaid SIM card removes a lot of the guesswork that may come for those who do not have innate roaming included in their phone contracts. 

SIM Card vs Public WiFi

For some, foregoing personal data and fully relying on free public WiFi is an option. This is often done as it entails no additional expenses or contractual obligations, but with that, there are a number of drawbacks. 

First off, visitors are often under the heel of WiFi internet accessibility. Though Japan is often celebrated for its technological advancements (and often lives up to such praise), WiFi access is actually somewhat rare compared to other countries like Korea or Taiwan. Public WiFi access is often found in some cafes (predominantly large chain institutions such as Starbucks or Doutor), or places of accommodation . Many train stations offer public WiFi, however, accessing them often require a sign-up or log-in and aren’t always consistent or dependable, though the option is always there for those who need it. 

Additionally, security is a potential issue that may arise when operating solely on free public WiFi.

If someone is handling sensitive or personal information, they should be aware of the risks that may come up. Through a SIM card, data is used individually and kept private, avoiding these security risks. 

So given all these caveats, does foregoing personal data usage for free public WiFi work well for any visitors? For individuals traveling to Japan for business trip purposes and will predominantly be spending their stay at hotels , offices, or meeting spots, depending solely on the internet options provided at these locations may be more than adequate. Though, if one falls under this category, be aware that the security risks still exist. Working with confidential information should be avoided or done with a reliable Virtual Private Network (VPN) service. 

Working at a cafe is a common option for remote work

SIM Card vs Pocket WiFi

Pocket WiFi devices are one of the primary means of mobile data usage for travelers to Japan. In fact, pocket WiFi devices are often compared and contrasted to individual SIM cards during pre-departure preparations and research due to their similar functions, similar price, and popularity.

Through Japan Experience, pocket WiFi devices are available for rental at a price starting at 44 USD for 5 days and SIM cards are available for purchase at a price starting at 29 USD for 8 days . 

If one has reserved a pocket WiFi device, they will need to pick it up at the airport upon arrival or have it sent to their place of stay within Japan. From here, it is simple to use and just requires a password to connect to the WiFi hotspot. 

A pocket WiFi carries some stand-out benefits, most notably the ability to host multiple connections at once through a hotspot. This is especially beneficial to those traveling within groups or families who wish to share internet access along with those needing to operate multiple devices, like tablets or laptops, during their trip. 

There are some things to keep in mind, however, that may make an individual SIM card the better option for some visitors. As previously mentioned, the pocket WiFi is a separate device that must also be carried around to use. In addition, it has its own power source. While the pocket WiFi has a long and dependable battery life, it will need to be charged and if it runs out of battery, the network will not be accessible. There is also a range limit of 20 meters for hotspot access, and while this is quite far and adequate for most situations, it is something to keep in mind. Individual SIM cards are inserted into mobile devices and thus have no physical accessibility limitations and can be used the entire time without the need of a hotspot connection. 

Ultimately, both options boast a range of benefits for mobile data in Japan and which is best depends largely on the conditions individual travelers will face during their stay. 

Is a Short-Term Japanese SIM Card right for me?

A short-term Japanese SIM Card is a great option for using mobile data in Japan in a cost-effective manner, but its utility in comparison to other options largely depends on a traveler’s specific conditions and needs. Essentially, the continued use of one’s personal device with high speed internet helps to streamline the travel process more, so adequate research for the best options is an essential part of pre-departure preparations. Either a temporary Japanese SIM card or a rentable pocket WiFi device will satisfy the needs of a majority of travelers and ensure that one is connected the entire time of their stay in Japan.

How To Buy A SIM Card In Tokyo

Yes, it is possible to buy prepaid data-only SIM cards for your smartphones or devices in Japan. Here, I’ll tell you the best deal based on my own experiences. I’ll also present another good option: pocket wifi (mobile router) rentals.

The Takeaway:

• You can purchase a Japan SIM card, eSIM or pocket wifi to pick up on arrival at Narita, Haneda or Osaka airports. Staff at the pickup point will help you configure your device. This is probably the simplest option.
• Alternatively, you can buy Japan Travel SIM cards like the IIJmio Japan Travel SIM at Bic Camera shops which are everywhere.
• You can make voice calls using services like Skype or Facetime with data-only SIMs.
• Another good option for travelers is to rent a pocket wifi (mobile router) like the Ninja Wifi Router .
• If you are going to buy a SIM card in Japan, you’ll find that Bic Camera shops have the best selection and they will also install the SIM card for you if you wish (for ¥2,200).

The Details:

• Wifi is common in Japan and you’ll usually find it in hotels and guesthouses, as well as many coffee shops and restaurants. But, if you want to be online everywhere you go, you’ll need to buy a SIM card. You can now buy a data-only SIM card in Japan, either online for pickup on arrival at Narita or Haneda airports or by buying over-the-counter once you’re in Tokyo.

What You’ll Need

• First, you'll need an unlocked smartphone or device to use a prepaid SIM. You should be able to configure the APN settings yourself. Note, however, that if you buy your SIM at a Bic Camera shop, they will do the installation and set up for ¥2,200.

Data-Only Prepaid SIM Cards Available to Tourists in Japan

There are three major prepaid data-only SIM cards available to travelers in Japan:

IIJmio Japan Travel SIM

B mobile visitor sim.

I’ll cover IIJmio and B Mobile in detail below. Bic SIM is similar.

Check Hotel Availability

Destination, check-in date, check-out date.

• IIJmio offers two prepaid SIMs to travelers in Japan: 1.5GB/30 day (¥1,980 at Bic Camera shops) 3GB/30 days (¥2,480 at Bic Camera shops)
• You can buy them at Bic Camera shops, which can be found in most major Japanese cities. Tokyo is filled with Bic Camera shops. If you've just arrived at Tokyo Station, the Yurakucho Branch is about 10 minutes’ walk from the station. Enter via the Kokusai (International) Forum Entrance (the closest to Tokyo Station) and you’ll see the SIM card display almost immediately in front of you (note that they tend to move these things around, so this may change by the time you read this). For other branches in Tokyo and the rest of Japan, use this Bic Camera store locator to find a convenient branch.
• B Mobile Visitor SIM: 5GB/10 days (¥1,980 purchased online)
• While this offers less data than the IIJmio Japan Travel SIM, it can be purchased online or in shops here in Japan. Here is a list of shops selling B Mobile Visitor SIMs. Here is the online B Mobile Visitor SIM purchase page . If you buy one online, they can ship it to your hotel or to a post office at your arrival airport (they will hold it for you until your arrival and you can pick it up there).

Pocket Wifi (Mobile Router) Rental

• Another great option for visitors to Japan is to rent a pocket wifi unit. This is good for people who have locked devices and those who don’t want to bother with APN settings. A pocket wifi is also a great option for people traveling in a group (several people can log onto one device). And, these units have unlimited data and they tend to be very fast.
• You can rent a wifi router online which will be waiting for you when you arrive at the airport. This gives you unlimited data and you can connect up to 14 devices. You simply drop the unit off at the airport too when you leave.

Using A Travel SIM Card In Japan: The Best Brands And How To Use One

October 26, 2023 November 3, 2023 by Angela Ayson

Using a travel SIM card has become essential when going on a trip to Japan nowadays. 

Aside from letting you stay connected to your loved ones while you’re abroad, having an internet connection allows you to access Google Maps and translating apps—both of which are very important when traveling to a country like Japan. 

Are you wondering what is the best travel SIM card to use when you’re in Japan? Worry no more! We’ve got a rundown of the best SIM card and eSIM brands for you to try on your next trip, including how to use them and where buy them!

Best Travel SIM Cards and eSIMs In Japan

Here are our top picks for the best travel sim cards in Japan:

DOCOMO  is one of the top data providers and mobile phone operators in Japan. Access high-speed internet at all times while you’re traveling by purchasing the Docomo Japan travel eSIM! Once purchased, you will receive a voucher carrying a QR code that you’ll scan to set up your eSIM. 

Enjoy unlimited 4G data for seven (7) days of use. Note that your internet speed will be reduced to 256 kbps after you reach your daily limit for the day.

Where To Buy Japan Travel SIM Cards

You can buy a Japan travel SIM card upon your arrival in Japan! There are several shop counters at airports where you can buy these SIM cards; however, do note that these shops are not open 24/7. Alternatively, you can also buy SIM cards via vending machines and electronic shops.

Many network providers also allow online pre-orders via their official website. You can choose to have your travel SIM card either shipped to you prior to your flight or pick them up at airports or hotels. 

For your convenience, though, it would be best to purchase your SIM card or eSIM in advance on KKday. 

How To Use Japan Travel SIM Cards 

Japan travel SIM cards are so easy to activate! Most physical SIM cards are just plug-and-play—all you have to do is insert them into your smartphone. Some require a short registration for you to activate the data. This all depends on the network provider whose service you are using.

Meanwhile, eSIMs are activated through a unique QR code sent to you by your choice of provider.

The Best eSIMs for Visiting Japan

eSIMs are perfect for traveling. Worrying about SIM trays or losing microscopic SIMs between the sofa cushions is finally a thing of the past! What’s more, the Japan eSIM market has exploded, with a wide range of offerings from both domestic and international players. To help you choose the best eSIM for your trip, we tried out all the eSIMs that we could get our hands on.

You can get an eSIM with a real Japanese phone number, even if you're just visiting. The voice + data eSIM from Mobal starts at [price amount=4620] for 30 days. Bonus -- the bulk of profits go to charity. -->

Japan eSIMs tested and compared

First, a quick summary of what we found when we tested the eSIMs: If you’re curious, here’s how we tested the Japan eSIMs .

What exactly is an eSIM?

It’s a virtual SIM that you can download and install onto your phone directly, so no more fiddly physical SIM cards. Most phones released since 2019 have the option to use an eSIM, with Apple’s US iPhone 14 and 15 being eSIM only. eSIMs are convenient when you want to change your carrier, such as when abroad, as you can connect to a new provider in seconds without removing your existing physical SIM card.

Japan eSIMs for tourists and short-term visitors

Here’s a quick overview of some of the Japan eSIM options for your trip. This is not an exhaustive list; just an introduction to some of the main players in the market.

eSIM Japan offers economical data-only plans for visitors to Japan. Their plans come in two varieties: a general Japan plan, and city-specific plans for Tokyo, Osaka, Kyoto and more. They are all the same price, and for all intents and purposes are the same as the general plans. However, all plans work throughout Japan.

When we ordered the 2GB/day Japan Unlimited Pro eSIM, a QR code landed in our inbox immediately, so you can even decide to pick one up while waiting to pick up your luggage at the airport. The time from purchase to use took less than 15 minutes.

The plan begins as soon as you scan the code and install the eSIM. Plans have a set time limit (3, 5, 7, 12, 15, or even 90 days) and a data limit (3GB, 5GB, 10GB, or unlimited), so you can choose a plan that works for the length of your trip. Plan prices vary based on length, from US$ 3.99 for a basic 3-day plan, to US$ 26.99 for an unlimited 12-day plan.

eSIM Japan is provided by China Mobile Hong Kong, but roams to Japan’s KDDI au and SoftBank networks (you’ll need to enable roaming to use it). Despite the roaming, it was fairly fast, with a download speed of 38.27Mbps on average. Webpages loaded in a flash, and both video calling and streaming were smooth, with no lags.

Note: If you are in Hong Kong or Taiwan, you’ll need to use real-name registration. Otherwise, no signup is required.

Mobal eSIMs

Popular local provider Mobal recently launched a line of eSIMs for Japan. They sell seven different data-only eSIMs, ranging from a basic 1GB, 8-day eSIM for ¥ 1,920 , all the way up to a hefty 50GB, 31-day eSIM for ¥ 4,900 . They also have a voice and data SIM.

Mobal uses the major Japanese network Docomo, which means that you won’t be roaming. It’s 4G LTE and coverage is countrywide. For activation of the data SIMs, it takes about 15 minutes. We received an email with a link to their service website after 5 minutes. This led us to a page where we waited for our eSIM QR code to be ready for another 10 minutes.

In terms of performance, Mobal is about middle of the pack, at an average of 24.76Mbps. Websites loaded quickly, and video calling was fairly smooth. Overall, it’s a solid, reliable eSIM.

Mobal voice + data eSIM for Japan

There is also a voice + data eSIM , which has an initial fee of ¥ 2,970 . When you activate your eSIM, you’ll need to choose a monthly plan, ranging from 1GB/month for ¥ 1,650 , to 30GB/month for ¥ 4,378 . There is no minimum contract period, and there are no cancellation fees, making it a viable choice for both travellers and residents alike. You get a real Japanese phone number with this eSIM. We tested out the 7GB plan.

Note: Due to regulations in Japan, the voice + data eSIM cannot be emailed to customers; your access code will need to be posted to your residence overseas, or otherwise picked up in person in Japan. You need to apply in advance, upload an ID document and wait for a delivery. Once you get your package in the mail, you need to activate your Mobal eSIM on the Mobal website. You’ll enter a 32-digit EID, then wait for Mobal to activate your eSIM and provision your new Japanese phone number. Technical support is available via email and a web form, though most questions can usually be solved by having a peek at Mobal’s FAQs page.

If you’re in the market for speed, Airalo isn’t going to play games with you. Airalo eSIMs roam on SoftBank, one of Japan’s major carriers, offering dependable data on the go. Their Moshi Moshi eSIM line of eSIMs has 7, 15, and 30-day packages. The 7-day package is the bare minimum, with only 1GB of data for US$ 4.50 . The 15-day plan offers 2GB, and at the upper end, the 30-day plans come in 3, 5, 10, and 20GB increments. For those of you who burn through your data, that 20GB package will set you back US$ 26.00 .

Getting the Airalo eSIM took no time at all. We signed up for the 2GB/15-day Moshi Moshi eSIM, and after paying, we were immediately taken to a page with our eSIM QR code waiting. We were 100% good to go within 15 minutes. Note that sign-up is required for this eSIM.

When it came to our speed test, this eSIM left all of its competitors in the dust. Our testing had a lightning fast average download speed of 141.61Mbps. Websites loaded almost instantly, and YouTube videos didn’t stop to buffer once. Even our awkward video calls didn’t make this eSIM break a sweat. If you’re the sort of person who really works your data to the bone, Airalo is a good choice.

Ubigi is a global eSIM provider currently offering eSIMs for over 200 destinations. A relatively new name in the Japanese eSIM market, they nonetheless have plans to cover most needs. From economical single day 500MB plans for ¥ 390 to beefy month-long plans with 50GB of data for ¥ 9,700 , there’s something for all travelers.

Ordering from Ubigi is a snap. Once we paid, we had a QR code emailed to us in seconds. One quick scan, and we were ready to go. Like most others on this list, Ubigi works with NTT Docomo for reliable coverage across Japan. The company behind Ubigi is Transatel, which is actually owned by NTT.

We tried the 3GB Ubigi eSIM. In our testing, we experienced average speeds of 73.72Mbps, and webpages loaded in a flash. YouTube playback was smooth with no buffering, and our video calls were lag-free. Overall, at this price point, Ubigi offers excellent quality and speed that make them a strong contender.

World eSIM is brought to you by Vision Inc. — the folks behind travel wifi name Ninja Wifi . They have nine Japan eSIMs, with various combinations of data and validity periods. We ordered the 3GB/5-day plan for US$ 8.50 , but you can also get 5GB/10-day, 10GB/15-day, and 15GB/20-day eSIMs. If you prefer to get a daily amount of data, there are 500MB/day x 3 days ( US$ 4.50 ), 1GB/day and 2GB/day options.

Getting our eSIM was straightforward. After signing up on the World eSIM website, we paid and had a QR code sent to our email instantly. A quick scan, and we were ready to go. Download speeds averaged 99.15Mbps, and our streaming was smooth. We found that this was one of the best eSIMs for video calling, during our test. It’s a solid choice, overall.

Sakura Mobile

An established SIM and wifi provider that’s popular with people staying in Japan both short and long term, Sakura Mobile also has a line of eSIMs. Prices scale depending on how long you’ll be staying (up to a maximum of 90 days), and how much data you want. Their cheapest option — a 3-day, 1GB data-only travel eSIM, will set you back ¥ 2,100 .

We tested the 3-day, 3GB data-only eSIM, which cost ¥ 2,750 . There was no option to install it directly through the Sakura Mobile website; the QR code and instructions were emailed to us. The user interface was a little clunky, but we managed to get the eSIM set up in under 15 minutes. We didn’t need to activate roaming to use it.

In terms of performance, Sakura Mobile’s download speeds averaged 84.46Mbps, although they varied significantly across test platforms. Video playback as well as calling was smooth, though, and we were satisfied with the overall performance.

Sakura Mobile voice + data eSIM for Japan

There is also a voice and data eSIM available on longer-term contracts. You can choose between a 4GB, ¥ 3,278 /month plan, or a 25GB, ¥ 4,378 /month plan. There is a ¥ 5,500 activation fee on both.

As with all voice-calling products in Japan, identity verification is required. This can be performed electronically using facial-recognition software, if you have a Japanese residence card or Japanese driver’s licence. If you’re coming from abroad, you’ll need to take your passport to an airport pick-up counter to get your QR code.

Singapore-based eSIM player Jetpac have a range of plans for Japan, starting from 3GB for ¥ 1,500 and going up to 25GB for ¥ 3,765 . When we did our test, there was also a promotional 1GB plan for ¥ 150 . We opted for the 3GB eSIM, however. Once we had paid, the Jetpac eSIM was provisioned instantly.

When it comes to speed, the Jetpac eSIM was one of the top performers during our tests. Download speeds averaged an impressive 122.7Mbps, and streaming as well as video calling was super smooth.

You need to enable roaming to use the SIM, though once up and running it will roam on the local SoftBank and KDDI networks. Jetpac pushes customers towards their app, but it’s not actually necessary to download it. A nice little perk is that the Jetpac eSIM gives you access to 1,100 airport lounges around the world; you can use them in the event of a flight delay or cancellation.

Which is better for your Japan trip: An eSIM, or a physical SIM card?

Even with more providers arriving on the scene, the options with physical SIMs are still superior to what you can get with eSIMs. For example, only one of the eSIMs listed here includes a Japanese phone number with calling ability (that’s Mobal ). So if you’d like something more inconvenient but with better options, check out our guide to prepaid SIM cards for travel to Japan .

Also, keep in mind that you might need a second device to install an eSIM, as the second will display the QR code for your first device to scan. If you don’t have a second device, you’ll need some help to install the code — perhaps by asking someone to take a photo of your QR code and then scanning it from their phone.

How did we test the Japan eSIMs?

First of all, a disclaimer: Testing the performance of eSIMs is inherently difficult, due to transient network conditions. You can test the same connection, on the same phone, in the same place, twice in a five-minute interval and get two completely different results for speed and latency.

For our most recent test, we rented six identical Google Pixel 7a handsets, and took them to a studio in Tokyo to test out the eSIMs mentioned in this article. While our video producer recorded the tests, our CEO installed the eSIMs and went through the following:

• Five speed tests, all using the Ookla app and different test servers, assessing the download and upload speeds (we did four tests for upload speeds), as well as latency
• Watched videos on YouTube to assess streaming capabilities
• Made short video calls to look for lag

Our CEO then retested some of the eSIMs the following day, at a different location in Tokyo, to compare results. Due to both Mobal and Sakura Mobile experiencing severe throttling on the initial test day, we have used the data from the second day for their eSIMs.

Some of the eSIMs had to be run on the same device, meaning that not all tests were simultaneous. We know that our testing method isn’t perfect, but it gave us a good idea of the performance of the different eSIMs. We excluded some eSIMs from the article where we had concerns about the ordering process, performance or pricing.

A word on speed tests: We strongly recommend that you don’t run speed tests with your eSIM, as they BURN through data. A single test could use 300MB or more!

While we do our best to ensure it’s correct, information is subject to change. Prices are approximate. This post was first published in October, 2020 and was last updated by Carey Finn on April 1st, 2024.
