Mobile Phones

Until recently, getting a Japanese mobile phone meant a two-year contract, and penalties for early cancellation. The major smartphone brands were only available with SIMs locked to a particular network. The three main networks (SoftBank, docomo and au) have already been abolished two-year contracts for individual plans, it is now possible to buy unlocked smartphones from electronics stores.

Handset contracts

In order to buy a handset you will need identification and contact information, such as your residence card, passport, and address in Japan. You must also have a Japanese bank account or a credit card in the contractee’s name. A range of plans are available as well as discount services, so check with the various providers before you make your purchase.

The following are the major mobile phone operators in Japan.

au, operated by KDDI Corp, is one of Japan’s three largest mobile networks.

Nationwide, they employ bilingual staff and a video chat translation service with 12 languages, to help customers throughout their contract procedures.

Using Handsets from Overseas

It is possible to use non-GSM 3G, 4G and 5G phones in Japan via international roaming. It is also possible to use a SIM-free device with a Japanese SIM, if it is compliant with Japanese regulations. See the section below on SIM-free phones for on information on data and voice plans.

SIM-free Phones

Unlocked phones can be purchased from electronics stores, while the mobile networks listed above are required to provide new phones unlocked if requested (though some will only unlock after a set period from the start of the contract). If you have an unlocked phone, you can get data and voice SIMs through a number of providers.

The advantages of going with this option include lower monthly charges, shorter contract terms and potentially cheaper fees for early cancellation. However, as handsets are not part of the contract, it is not possible to split the cost over a two-year period. Additionally, as most SIM-only providers piggy-back on the networks of the major mobile providers, the internet connection may be less reliable.

Companies offering SIMs include BIGLOBE, DMM Mobile, IIJmio, mineo and Rakuten Mobile. Most cards must be purchased online. For in-store assistance, electronics chains such as Bic Camera, Yodobashi Camera and Yamada Denki also offer SIM card contracts. The following online operators offer English service:

Prepaid Phones

Simple prepaid phones are another option for those who are not living in Japan long enough. SoftBank offers simple prepaid feature phone and smartphone handsets for a reasonable upfront fee. A certain amount of credit is included at time of purchase (which must be used within a given time limit or be lost) and additional credit can be purchased through SoftBank’s website and through prepaid cards sold at convenience stores and SoftBank stores. For foreign residents, a valid residence card (with current address recorded) and passport are required to apply. The contract will be terminated if the phone is not topped up with credit within the first year of purchase, and thereafter may be terminated if there is no top-up for a 60-day period. There is a cancellation fee for terminating the contract before a year is up.
