What you can receive from the Ward Office

Resident Record (Juminhyo)

There are some circumstances in which you’ll need to provide a Certificate of Residence (Juminhyo) to confirm your personal information and address. This can include when you’re applying for a contract for a mobile phone, for example. The local ward/municipal office will issue you a Juminhyo upon request. It generally costs around 300 JPY (fee varies depending on the ward) to have a Juminhyo issued.

My Number (mai nambā)

As soon as you finish your registration, you will be sent a My Number (マイナンバー mai nambā) notification card to your address. 

My Number is also known as an Individual Number (個人番号 kojin bangō). This is a 12-digit ID number issued to every resident of Japan and is used for various administrative purposes, including taxation and social security. It is basically the Japanese version of a Social Security Number.
