How to Buy a Local SIM Card in Japan

A local SIM Card is useful if you are visiting Japan for business or for an extended period of time. This will save money on phone calls and data charges. Foreign visitors can purchase specific traveller SIM cards, which are available throughout the larger cities. There are a number of different SIM cards for tourists, which offer a variety of options. Here you will find all the information about how to buy a local SIM card in Japan.

Prepaid Data Only SIM Cards in Japan

Whilst free Wi-Fi is available in most hotels, coffee shops, and restaurants, to be connected throughout your trip, a data-only SIM Card is the best option. The country has had many restrictions on local SIM cards for foreign visitors; however, those who are visiting Japan for tourism will easily be able to purchase one.

This type of SIM will only offer access to the internet rather than phone calls and text messages. These can often be ordered in advance and picked up from the airport upon arrival. The following providers, among others, offer data-only SIM cards:

Coverage is excellent across cities and most rural areas, making data-only SIMs a reliable choice for navigation, translation apps, and everyday travel needs.

Alternatively, if you’re already in the city, there are places to purchase these SIM cards in-store. The majority of Bic Camera or Yodobashi Camera stores, which are in major shopping locations, sell these prepaid data SIM cards and can assist with setup for a small fee, although installation is usually straightforward. Bic Camera shops can be found throughout the country. There are two types of prepaid data SIM cards for foreign visitors that last for either 30 days or 3 months.

Voice and Data SIM Cards in Japan

For travelers who need a Japanese phone number - whether for certain local apps, account verification, or making calls in emergencies - a voice + data SIM can be a useful option. Providers such as Mobal, Sakura Mobile, and Japan Wireless offer these SIMs.

These typically require ID verification (passport upload and sometimes proof of address) before activation, but once set up, they function like a local phone number. Plans vary in price and data allowance, so it’s worth comparing providers in advance.

However, most travelers can get by without a local phone number, as many apps and services work perfectly with a data-only SIM.

E SIMS in Japan

As one of the most technologically advanced countries in the world, it only makes sense that Japan has jumped on board the exploding E-SIM trend. Numerous E-SIM companies offer a service in Japan. These virtual SIMS can be ordered online from your mobile phone before or during your trip - no small fidgety SIM required! The setup process is quick, meaning you can get connected within minutes of activation! For E-SIMs for Japan and the rest of the world, we highly recommend Airalo.

*Note: Ensure your device supports eSIM and is unlocked. Most newer iPhones and Android phones work, but some older models may not be compatible.*

Other Options for SIM cards in Japan

Japan’s networks are primarily LTE and 5G, so older phones that don’t support these standards may not receive a reliable signal. In this case, another option is to rent a Japanese phone. These can be pre-ordered online and can be a practical alternative, particularly for travelers with incompatible devices

For those who opt for a prepaid SIM card, make sure to unlock your phone before entering Japan!

Another popular option is renting a pocket Wi-Fi device, which provides portable internet for multiple devices at once. This is a fantastic choice for groups or travelers with multiple phones, tablets, or laptops. Pocket Wi-Fi can be reserved online and picked up at the airport or delivered to your hotel, offering reliable coverage throughout Japan.
