For those thinking about filing a change of address before moving, we break down the essentials of the 14-day rule under the Basic Resident Register Law and clarify when submitting a change of address before move-in day constitutes false reporting. Experts explain which procedures (like filing at your previous residence, setting up mail forwarding, and arranging utilities) can be done early, and the correct order to do them in.
When moving to a rental property, many procedures are needed from filing a moving-out notice to updating your driver's license and bank accounts. If you get the order of procedures wrong, the workload multiplies. This article explains all address change procedures before and after moving in an easy-to-understand way.
Comprehensive coverage of address changes not just for your resident registration, but also for pensions, health insurance, driver's license, bank accounts, credit cards, and more. We explain what you must not forget and how to prioritize your tasks.
Your My Number Card contains your address information. When you move and your address changes, you must update your My Number Card's address at the same time as you submit your change of address notification (either a move-in form or transfer form within the same municipality).
As of 2026, My Number Card ownership exceeds approximately 90%, and online procedures using the My Number Card are rapidly spreading in moving processes. This article will comprehensively organize all My Number Card-related procedures after moving.
Your My Number Card contains address information stored on its IC chip and printed on its surface. If you don't update your address after moving, the following problems may occur:
Under the Resident Registry Law, you are required to submit either a move-in notification (if moving from another municipality) or a transfer notification within the same municipality within 14 days of moving. If you have a My Number Card, you can update your address at the same time.
For a move within the same municipality, you will submit a "transfer notification."
Required documents:
Process at the municipal office:
Even if the card's surface still shows your old address, since the IC chip information has been updated, there will be no problem with electronic identity verification.
If you are moving from another municipality, you will need to submit a "move-out notification" at your previous municipality's office and a "move-in notification" at your new municipality's office.
Step 1 (Previous municipality's office):
Step 2 (New municipality's office):
Starting in 2023 and gradually expanded, the "moving procedure" feature in My Number Portal allows you to apply for a move-out notification online from a PC or smartphone (with NFC capability). While the move-in notification must still be submitted at your local municipal office, you can make reservations and prepare documents online in advance.
With the 2023 system revision, if you have a My Number Card, you can apply for an online move-out notification through My Number Portal without having to visit your previous municipality's office.
| Procedure | Method | Deadline |
|---|---|---|
| Move-out notification (previous address) | My Number Portal (online) or previous municipality office | Within 14 days before or after move-out |
| Move-in notification (new address) | New municipality's office (in-person required) | Within 14 days of move-in |
| My Number Card address change | Processed simultaneously when submitting move-in notification | Simultaneous with move-in notification |
If you miss the deadline for submitting your move-in notification (within 14 days of moving), you technically violate the Resident Registry Law, and you could theoretically be subject to a fine of up to ¥50,000. However, fines are rarely actually imposed, and if you explain your reason for the delay (such as hospitalization or work-related circumstances), your submission will usually be accepted.
Even if the deadline has passed, don't ignore it—visit your municipal office as soon as possible to complete the procedure.
Even before submitting your move-in notification, you can still use online eligibility verification (My Number Insurance), but address information mismatches may be flagged. This will be resolved once you promptly submit your move-in notification.
If multiple address change stickers have accumulated and made your card thick, you can apply for a replacement card (replacement fee: ¥800).
If you will be away from Japan for more than a year (such as for overseas assignment), you must return your My Number Card to your municipal office. You can reapply once you return to Japan.
By law, your registered address must reflect where you actually live. Failing to move your registered address for tax purposes or similar reasons constitutes a violation of law and may affect your right to vote and access to government services.
The most efficient way to update your My Number Card address is to handle it at the same time as you submit your move-in notification at your municipal office. Don't forget to complete this procedure and keep your various services functioning properly.
After moving, you'll need to update your address not just with your resident registration, but also with your bank, credit card company, insurance provider, and various services. We'll explain the checklist and priorities to ensure you don't miss anything.
