Phone and internet

A Japanese phone number is one of the first things you need: banks, landlords, delivery services and many forms ask for one. Once you have your residence card with your address, getting a contract is quick.

The bank and phone puzzle

Many banks want a Japanese phone number, and many phone plans want a Japanese bank account or credit card. The usual way round it is a plan that accepts a credit card from abroad, which most big carriers and some budget brands do. A data-only eSIM can cover your first days, but it will not give you a phone number.

Choosing a plan

The big carriers are docomo, au, SoftBank and Rakuten Mobile. Each also has cheaper online brands, such as ahamo (docomo), povo (au) and LINEMO (SoftBank), plus sub-brands with shops, UQ mobile and Y!mobile. Budget providers (MVNOs) use the same networks for less, with slower speeds at busy times.

You need your residence card with your address on it and a way to pay. Buying a new phone on instalments involves a credit check that new arrivals often fail, so bringing an unlocked phone is easiest.

Home internet

Most homes use fibre (hikari). Check first whether your building already has a line. If not, installation needs the landlord's permission and often takes two to four weeks, longer in spring. A home wifi router that works over the mobile network, or a pocket wifi, can bridge the gap.

Handy for your move

Stay connected until your contract starts

A tourist SIM or pocket wifi keeps you online for your first weeks, while you get your residence card and a Japanese phone contract.

Tips

  • Bring an unlocked phone that supports eSIM. It makes signing up online much faster.
  • Many apartment buildings come with free or cheap internet already set up. Ask before signing a separate contract.
  • Contracts with long minimum terms and cancellation fees are less common than they were, but check before you sign.
