1 How do I sign up for a mobile phone or smartphone in Japan?

For those migrating to Japan from overseas, mobile phones and smartphones are an absolutely must have as a means of communication as well as for using map applications and translating Japanese.

To purchase a mobile phone or smartphone in Japan, you will need to visit a mobile phone shop. Most mobile phone shops in the city have staff who can speak foreign languages, but some stores do not support English or Chinese, so it would be in your best interest to have someone who can interpret come with you or select store that can support your native language.

You may have heard that you will need to have a "foreigner registration certificate" in order to enter into a contract with Japanese mobile phone companies and it is often written on their homepages but that is actually not the case. In general, you have to present the required identification documentation for a new mobile or smartphone contract however, when foreign residents sign a contract with phone companies, the company's main concern is your ability to pay. There are three main conditions you have to confirm to satisfy the requirements. You have to confirm that you are "over 20 years old", your foreign resident identification card has to show that you are "allowed to remain in Japan for at least 2 or more years" and that you pay your monthly charges "with a credit card or bank account". If you can provide this information, you are good to go.

It may seem difficult for those under the age of 20 to obtain a mobile phone or smartphone but the reason most Japanese junior high school students have a mobile phone is because they have signed up under their parent's contract. Minors who apply directly will be refused service. This is a strict rule in Japan, so if you are a minor and live in Japan, you will need to ask a relative living in Japan to add you to their service contract.

In addition, most major mobile phone companies in Japan provide service contracts based on the assumption that the customer will use the service for two years. Therefore, if you can confirm your stay in Japan will be for two or more years with your foreign resident card, you can get service relatively easy. In some cases, if you can pay the cost of the phone in advance, some companies may allow you to have service even if you plan to stay for less than two years, so check with the person in charge of each company when inquiring.

If you already have a credit card in your name, you can easily pay for your mobile phone or smartphone. However, if you do not have a credit card, you will need to open a bank account in your own name at a Japanese bank. If you have trouble opening a bank account in Japan, or if you can't open an account due to various circumstances, you should have a credit card in your name that you can use in Japan.
