IP Phones

IP phones have various advantages such as cheaper rates when making long-distance or international calls. You can easily apply for it when you set up Internet connection to your home. However, you need to be aware that it cannot be used at times of blackouts.

Pay Phones

Photo_Payphoneskoushuu denwa (, Pay phones) are easy to use and are usually located near train stations, in major public buildings, or at stores and can be used with 10 Yen coins, 100 Yen coins or prepaid telephone cards. Pay phones do not give change for 100 Yen coins. Telephone cards are available at station kiosks and convenience stores. Because more and more people have mobile phones, pay phones are becoming harder to find.

Mobile Phones

Japan is an industry leader in mobile phone technology, and mobile phones (“keitai denwa” or just “keitai”/ “携帯電話”) are regarded as indispensable for daily life in Japan. In addition to the increasingly popular smart phones (“スマートフォン”, abbr. “sumaho” / “スマホ”), even regular Japanese feature phones (aka “garakei” / “ガラケー”, named after “Galapagos syndrome” due to the evolution of Japanese mobile technology, taken-for-granted in Japan but unique in comparison to the rest of the world) can come packed with technology such as camera, games, TV, internet browser, and mobile wallet. While the rest of the world sends text messages primarily via SMS, Japanese mobile phones come with their own e-mail addresses and send texts via e-mail.

Using mobile phones

Below are some of the options you can consider when using a mobile phone in Japan.

  1. If you have a 3G or 4G phone, you can use it via international roaming (note that this is not applicable to GSM phones). There is the convenience of not having to change your phone number, however, costs can get very high.
  2. If your handset is SIM free, is compliant with Japanese regulations, and meets technical requirements, you can continue using your phone with a new SIM card. There are several types of SIM cards including prepaid, postpaid, and rental, and costs are reasonable.
  3. For those planning to stay in Japan for some years, buying a new phone from a Japanese company is an alternative. While the advantage of this is fast and stable connection, in most cases the contract is renewed every 2 years and is subject to a penalty when terminating use in the middle of a contract.
  4. There is a lot of paperwork involved in starting a new contract.
  5. Simple prepaid phones are another option for those who are not living in Japan long enough to fulfill a two-year service contract and do not want to pay for the handset up front. To activate and keep a prepaid phone valid, credit for minutes are purchased at sellers or convenience stores at regular intervals. Cell phone minutes are consumed only when making a call, not receiving a call. While minutes are expensive, email text is usually free. Even when purchasing a prepaid phone, customers are required to show proof of identity and residence in order to discourage criminal abuse.

Buying mobile phones

In order to buy a handset, make sure to have your identification and contact information ready, such as your resident card (alien registration card), passport, and address in Japan. A range of plans are available as well as discount services, so check with the websites or shops before you make your purchase. Following are the major mobile phone operators.

au’s foreign language support ensures customer satisfaction from phone purchase to contract’s end.
