Your Prepaid SIM Card Options for Travel in Japan

You land in Tokyo and ride the train into the big city. Maybe you stand in the middle of Shibuya’s Scramble Crossing , delaying traffic while you take a selfie. Or you hit up a restaurant, pointing at a random photo on the menu and hoping the waiter gets what you’re trying to order. And when it arrives, the first thing you think is, “I need to post this to make my friends envious.” Here’s the lowdown on getting a Japan SIM for your visit, for your data and voice communication needs.

Note: This article is about SIMs for a short stay in Japan. If you’re planning on living in Japan or you’re here for an extended period of time, see our article on Japan SIM contracts .

Short-term Japan SIM options for tourists

I’m here for a week or two and just need to update my status every dayyyyy.

That’s fine; if you order your SIM in advance, you can get online the minute you pick it up at the airport (all companies provide some form of airport pick-up). This isn’t an exhaustive list; just our top picks of prepaid Japan SIM cards. Keep in mind that some of them can be recharged with extra data.

More about each of the providers

Mobal

With the Mobal voice + data SIM , when your 7GB is up, data is still available at slower speeds. Top-ups can be purchased. 60-, 90-day and long-term packages also possible. If you’re traveling from China , you have access to a range of other prepaid packages . Free shipping to many countries, or pick-up at Narita or Haneda Airport, as well as Fukuoka, Kansai, Nagoya and Sendai airports and downtown Tokyo and Osaka. As with all voice-calling products, the voice + data SIM carries a ¥ 3,000 initial fee, which is included. On the data-only SIM, speeds may be temporarily reduced if more than 3GB is used in a day.

Simcard Geek

Simcard Geek has other SIM plans available. There is free shipping to many countries, or pick-up at the post office at Narita Airport or at other major airports in Japan. Fair usage applies, and speeds may be temporarily reduced if more than 3GB is used in a day.

Sakura Mobile

Sakura Mobile SIM cards come pre-activated, so you simply plug and play. Longer-term SIM deals also available. Fair usage applies to data.

OCN

OCN travel SIMs are available at airports, as well as major electronic retailers and a range of other stores. Prices are approximate. Maximum (theoretical) speed of 788Mbps; after 100MB has been used, speeds are throttled to 200kbps. Chinese and Korean language call center support available. SIM cards must be returned after use.

IIJmio

Called Japan Travel SIMs, IIJmio SIMs are available at airports and electronic stores countrywide. Other plans also available. Like OCN, prices are approximate, and the maximum (theoretical) speed is 788Mbps. SIMs can be recharged with extra data. Chinese language call center support is available.

SoftBank

The major telcos company offers a Japan Prepaid SIM for Travel direct on their own network. Prices approximate. SIM available at airports, SoftBank stores and major electronic retailers countrywide, as well as on Amazon.

b-mobile

Runs on the NTT DoCoMo network. SIM cards can be recharged with extra data. Delivery costs ¥ 370 to Japan airport post office, or ¥ 520 to a hotel/other accommodation. You can buy them at electronics stores and Aeon, too. SIM cards must be returned after use.

Can I make voice calls with these Japan travel SIMs?

With the exception of Mobal’s voice + data SIM, Japan’s SIM cards for short-term travelers are data-only , meaning you can’t call or text, or even receive phone calls. Although, if you’re still doing that, you’re probably one of those people who prints out emails and puts them in a filing cabinet. Or sends faxes. Society’s judgment, not ours.

Jokes aside, a partial workaround is to make VoIP calls through an app like Facebook Messenger, Skype, LINE or WhatsApp.

Buying a SIM card in Tokyo (or elsewhere in Japan)

Oops. Just ignored everything you said and went straight into town. Sorry.

No worries. Just look for a BIC Camera store (link in Japanese, but Shibuya, Shinjuku and Ikebukuro have quite a few) or Yodobashi Camera (also in Japanese) and grab yourself whatever Japan SIM card seems like the best deal. Bic SIM cards are fairly popular, we hear. For more information, see our guide on where to buy a SIM card in Tokyo .

Once you’re in the shop, you can say to the staff: シムカードを探しています。私に合うのはどれですか？ Shimu kādo wo sagashiteimasu. Watashi ni au no wa dore desu ka? That translates to “I’m looking for a SIM card. Which one would be best for me?” Many stores will have English-speaking staff, to make things easier.

Japan SIM cards for tourists: Frequently asked questions

Got questions about Japan travel SIM cards? We have answers.

Which SIM cards can I buy in Japan?

Mobal , prepaid OCN and Rakuten SIMs are among those you can buy on the ground in Japan. Other options include BIC Camera SIMs and IIjmio’s Japan travel SIMs. See our guide to buying a SIM card after arrival — while the focus is on Tokyo, it applies to all of Japan.

Where can I buy a Japan SIM card in Singapore, Malaysia, Hong Kong or The Philippines?

If you are traveling from one of the above areas, you can order a SIM card online and have it delivered before you leave for Japan, or—depending on the provider—pick it up at your local airport or landmark. For example, Mobal SIM cards can be collected at Singapore’s Japan Rail Cafe or the Nikkei Education Center in Hong Kong. There may be other options for your region.

How do I activate a Japan SIM card?

The exact steps depend on the provider, but generally it’s a matter of inserting the SIM into your phone and following the instructions provided. It doesn’t take long, and you should be able to start using it straight away.

Can I use an eSIM in Japan?

If you have a newer phone or tablet, you might be able to use a software-based eSIM card (instead of a physical SIM card) for your trip to Japan. Right now, Japan doesn’t have eSIMs for visitors, but you can use some global eSIMs. Read more about eSIMs in Japan .

Where are the big companies like Docomo and AU?

As in most countries there are network providers with their own retail brands, and smaller companies that operate on the networks of the big players like Docomo. You can get SIMs from the big players if you go into their stores, but they’re not really set up for tourists and the smaller players usually provide the best value.

Alternatives to SIM cards for tourists in Japan

Wait a minute, this is TokyoCHEAPo, not TokyoEXPENSIVEo, you want me to pay actual money for a service?

Not at all! You can be super cheap about data and use free wifi from teH giAnt Corporations. First up, a coffee chain that I understand is quite popular with the kids, has free wifi, providing you register at the link above. Then, just pop into a store and away you go!

Sign up? That’s WAY too much work.

OK, well, Apple happens to give out free wifi at various store locations with no login needed. And if there’s not one of those near you, the good ol’ Tokyo Metro provides free wifi too. AND if your home internet provider is part of the Fon network, you can use your own home internet login and passcode on Fon hotspots, which are practically everywhere in Tokyo. That’s not taking into account the myriad cafes and restaurants which also offer free wifi .

Speaking of Fon, they also offer travel wifi in the form of portable hotspots , which you can rent for your stay in Japan.

OK, calmed down now. Carry on.

It is worth pointing out a few other alternative solutions, too.

First up, if you have more than one device that requires the net, or a few of you are traveling together, you may want to consider a portable wifi device from a rental provider like the aforementioned Fon, or Ninja Wifi , who will give you a 20% discount. You can pick these routers up and drop them off at airports for convenience and they appear, from the ones we’ve seen so far, to have unlimited or very generous data allowances. For a more in-depth guide, see our popular guide to renting a wifi router .

AND FINALLY, you may be pleased to know that some mobile networks outside Japan offer cheap roaming packages. For example, data is free in Japan for T-Mobile USA customers on one of their plans. Read the fine print carefully though, as your data speeds may be heavily throttled.

And if a trip to the UK happens to be on the cards too or you just want to wince at how pricey Japan is in comparison, check out our London Cheapo Guide to UK prepaid SIM cards and where to buy a SIM card in London .
