My Number Card Address Update
If you have a My Number card, you need to update the address printed on it and in its electronic certificates after moving. Bring the card with you when you file your move-in notification (or change-of-address notification if you stayed in the same municipality) and it is done at the same time. Both notifications are due within 14 days of the move.

Move-In Notification
Register your address at the city or ward office of your new location. If moving from within Japan, you must complete the move-out notification first. If arriving from abroad for the first time, no move-out certificate is required.
Change of Address (Same City)
Required when moving within the same city or ward. This single procedure replaces both the move-out and move-in notifications.
