Register Your Bicycle防犯登録·bōhan tōroku

Legally required, costs a few hundred yen, and it is why the police stopped you.

Why it matters

Crime-prevention registration is required for bicycles, and police do stop cyclists to check it — foreign residents notice this more than most. An unregistered bike, or one still registered to whoever gave it to you, turns a two-minute check into a long roadside conversation. It is also the only thing that gets your bike back if it is stolen, and Japan actually does recover them.

What to bring

  • Residence Card在留カード·zairyū kādo
  • Receipt or transfer certificate販売証明書・譲渡証明書·hanbai shōmeisho / jōto shōmeisho

    If someone gave you the bike, you need a transfer certificate from them — a signed note with their details and the frame number.

How it goes

  1. 1

    Buying new: it is done at the till

    Any bicycle shop registers it for you as part of the sale for a few hundred yen. Just say yes. Keep the slip they give you.

  2. 2

    Given a second-hand bike? Re-register it in your name

    This is the case that goes wrong. A bike registered to a previous owner reads as a stolen bike to a police officer. Get a 譲渡証明書 (transfer certificate) from the person who gave it to you — their name, address, the date, and the frame number — and take it with your residence card to any bicycle shop.

    Say this

    自転車の防犯登録をお願いします。

    Jitensha no bōhan tōroku o onegai shimasu.

    I would like to register this bicycle in my name.

  3. 3

    If you are stopped, stay relaxed

    The officer is checking the registration number against a database. Carry your residence card — you are legally required to anyway — and it is a short conversation. Being unregistered is not a crime, but it takes much longer to resolve.

  4. 4

    Registration expires

    It lasts several years, not forever, and the term varies by prefecture. Re-register when it lapses, and transfer it properly when you pass the bike on.
