When relocating within Japan, setting up your “mail forwarding service” is just as critical an infrastructure task as updating your residential address at the city hall. Important contracts, credit cards, and official notices in Japan are, as a rule, delivered as physical mail.
Leaving mail to accumulate at your old address directly leads to fatal issues, such as personal information leaks and missed payment deadlines. This article explains the smart procedure for activating the free forwarding system provided by Japan Post, reducing your risk of lost mail to zero.
1. The Essential Infrastructure: “Tenkyo-todoke” (Forwarding Notice)
[Summary] This is Japan Post’s official, free service that automatically forwards mail sent to your old address to your new address for a full year after you move.
Japan Post provides a system called “Tenkyo-todoke” (Notice of Relocation) for anyone moving. Once submitted, any letters or parcels sent to your old address will be automatically forwarded to your new address for one year from the date of submission.
This service is entirely free of charge and functions regardless of which region in Japan you move to. Activating this forwarding system concurrently with your electricity and water setup immediately after your move is a fundamental step to maintaining your life foundation in Japan.
2. The Online Application Trap and the Reliable In-Person Process
[Summary] The online application (e-Tenkyo) requires automated phone verification using a Japanese mobile number. Bringing your Residence Card to a post office counter is the most reliable defensive measure.
While Japan Post offers an online service called “e-Tenkyo,” it presents a significant hurdle for foreign expats. The system mandates an “automated voice verification from a Japanese mobile phone number” to confirm your identity. Depending on your current mobile contract status, you may find yourself locked out of the process.
To avoid wasting time on unnecessary system errors, the most efficient method is the analog approach of physically visiting your nearest post office. Dedicated “Tenkyo-todoke” forms are available at the counter. Be sure to bring the following items:
- Identification: Your Residence Card (Zairyu Card) or Passport.
- Proof of Old Address: A driver’s license showing your old address, or a piece of mail previously delivered to your old address.
3. The Trap of “Do Not Forward” (Tenso Fuyo) Mail
[Summary] For security reasons, bank cards, credit cards, and important government documents are categorized as “Do Not Forward” and will be returned to the sender rather than forwarded.
Setting up the forwarding service does not guarantee that every single piece of mail will reach you. Herein lies a specific trap unique to the Japanese postal system.
Envelopes containing bank cash cards, credit cards, MyNumber-related notices, and visa documents are printed with a red mark stating “転送不要” (Tenso Fuyo / Do Not Forward). This is a strict security rule meaning, “If the recipient no longer lives at the registered address, do not forward it; return it to the sender to prevent fraud.” The postal forwarding service is merely a supplementary safety net. You must still promptly update your address directly with your bank and credit card companies after moving.
4. Q&A (Service Duration and Renewal)
[Summary] The forwarding period is one year from the date of submission. By submitting a new application before it expires, you can extend the service for another year.
Q. What happens after one year has passed?
A. Once the one-year forwarding period ends, mail sent to your old address will be returned to the sender. If you wish to continue having mail forwarded beyond the first year, simply submit a new “Tenkyo-todoke” at the post office before the current one expires. This will extend the service for an additional year (there is no limit to how many times you can extend it).
Q. Can I have my mail forwarded internationally if I am returning to my home country?
A. No. Japan Post’s forwarding service is strictly limited to domestic addresses within Japan. When your assignment ends and you permanently leave the country, the only solution is to proactively cancel services, close bank accounts, and ensure no further mail is dispatched to your Japanese address.
Conclusion: A Safety Net for Accurate Address Updates
The post office’s forwarding service is a powerful safety net designed to prevent the loss of important documents during the chaotic period of moving. However, relying on it too heavily is risky. After setting up the forwarding service, adopt a smart approach: immediately update your registered address with your banks, credit card providers, and telecom carriers to maintain a seamless living infrastructure.
