Moving into a Japanese apartment: what to do first

Three things have legal deadlines, and you can do all three in one city office visit. Everything else can wait.

Also at the city office: pension and My Number

If you are 20 to 59, live in Japan and are not in an employer's pension (厚生年金, Employees' Pension Insurance), you are in National Pension (国民年金, kokumin nenkin). Unless you are the dependent spouse of someone in an employer's pension, you sign up at your city or ward office and pay the contributions yourself (Japan Pension Service). Students with a low income can apply to postpone them under the student payment special rule (学生納付特例) (Japan Pension Service, for foreign residents).

You do not apply for a My Number (マイナンバー, your 12-digit individual number). About 2 to 3 weeks after your first residence record (住民票, juminhyo) is made, a letter with the number arrives by registered mail (簡易書留) at that address. If you are out, the post office leaves a notice and you arrange redelivery. The letter cannot be used as ID or as proof of your number, and it has a QR code for applying for a My Number card (Ministry of Internal Affairs and Digital Agency guide).

Do in week one

  • Internet: order it firstA home router works the day it arrives; fiber can take weeks and needs your landlord's permission. The GMO options on that page both need a credit card.
  • A SIM with a Japanese numberBanks and many landlords ask for a Japanese number. Prepaid SIMs have no credit check.
  • Utilities: electricity and gasGas usually needs someone present to open the supply.
  • A bank accountIf you work at an office in Japan, you don't wait six months.

Bank, phone and internet forms ask for your new address, some in Japanese and some in roman letters. The Japanese address converter gives you both.

Can wait

None of these has a deadline:

Moving-in FAQ

How long do I have to register my address after moving to Japan?

You must file the move-in notification within 14 days of the day you start living at the new address, and you cannot file before that day. Not filing without good reason can bring a non-criminal fine of up to ¥50,000 (Basic Resident Registration Act, Article 52).

What do I bring to the city office when I move in?

Your passport and residence card, plus the moving-out certificate (転出証明書) if you move from another Japanese city. If you arrive from abroad and your passport has no entry stamp, bring something that shows your entry date, such as a flight ticket stub (Toshima-ku). Other offices may ask for more, so check yours.

Do I update the address on my residence card separately?

No. Bringing your residence card to the city office when you file the move-in notification counts as the update (Immigration Services Agency). Without a report within 14 days you can face a criminal fine of up to ¥200,000, and your status of residence can be revoked after 90 days without good reason.

Do I have to join National Health Insurance?

Yes, if no other public health insurance covers you: Toshima-ku calls it compulsory. Notify within 14 days. If you are late, premiums are charged back up to 2 years in Toshima-ku, and medical bills in between are yours in full.

Do I need to apply for a My Number?

No. About 2 to 3 weeks after your first resident record is made, a letter with your number arrives by registered mail at that address.
