After a foreign employee arrives, secures housing, and successfully activates their infrastructure, an unexpected trouble often arises just when everyone thinks they can relax: “Utility bills for electricity and gas do not arrive, resulting in delinquency and eventual suspension of services.”
The primary cause of this trouble is that the foreign employee has not displayed their “name” on the mailbox of their new residence. In many countries overseas, it is common that “as long as the address and room number match, the mail will be delivered.” However, the Japanese postal delivery system operates on a completely different standard. This article explains the objective administrative procedures to prevent lifestyle breakdowns caused by the non-delivery of initial documents.
1. The Strict “Resident Confirmation” Rule in Japanese Postal Delivery
[Summary] Japanese postal workers verify if “the person on the address actually lives there.” If there is no name on the mailbox, it is returned as undeliverable.
The Japanese post office (Japan Post) enforces a unique “resident confirmation” to prevent misdelivery. The postal worker checks whether the addressee’s name on the mail matches the name displayed on the mailbox before dropping it in.
If the mailbox at the new residence is left completely “blank” with no name written on it, the worker will judge that “this room is still vacant” or “the addressee does not live here.” As a result, critical documents indispensable for a new life—such as utility bills, bank cash cards, and health insurance cards from the municipal office—are all returned to the sender as “address unknown.”
2. Secondary Risks Caused by Returned Bills
[Summary] If bills from utility companies do not arrive, electricity and gas will be forcibly suspended without the resident realizing they are unpaid.
During the first 1 to 2 months before the registration for automatic bank transfers or credit card payments is completed, paper “bills (payment slips)” will arrive in the mailbox. These must be taken to a convenience store and paid in cash.
If these bills are returned to the utility company due to the lack of a name label, the company will either assume “the contractor has not actually moved in” or treat it simply as “unpaid fees.” Within a few weeks, this directly leads to a sudden cut-off of electricity or a shutdown of the gas supply, often without even receiving a warning letter.
3. “Three Physical Actions” to Prevent Non-Delivery
[Summary] Ensure the mailbox displays both the Alphabet and Katakana name, and submit a “Notice of Relocation” to the post office.
HR managers should instruct foreign employees to execute the following three actions on the very day they move in.
- Action 1: Post a name label on the mailbox
A handwritten note or masking tape is perfectly fine. Attach your name to a conspicuous spot on the mailbox. - Action 2: Write the name in both Alphabet and “Katakana”
If the utility contract was made in Katakana, the postal worker might not be able to match it with an Alphabet nameplate. Always display both, such as “Smith John (スミス ジョン)”. - Action 3: Submit a “Notice of Relocation (Tenkyo-todoke)” to the post office
Simultaneously with labeling the mailbox, go to the nearest post office and submit a “Notice of Relocation” (online submission via e-Tenkyo is also possible). This officially registers the fact that “this person has started living at this address” in the post office’s database, ensuring reliable delivery.
4. Practical Q&A (Privacy and Corporate Contract Troubles)
[Summary] Answers questions on how to handle situations where employees do not want to show their names for privacy reasons, and addressing rules for company housing.
Q. The employee does not want to put their full name on the mailbox for security and privacy reasons.
A. It does not have to be the full name. Posting only the family name, such as “Smith,” or even initials serves as a sufficient guide for delivery. Another effective approach is to stick the name label “inside the mail slot” (where only the postal worker can see it when opening the flap) rather than on the outside. As long as the Notice of Relocation has been submitted to the post office, the risk of non-delivery is drastically reduced even with minimal information on the nameplate.
Q. The apartment is rented under the “company name (corporate contract).” How should the mail be addressed?
A. When delivering mail addressed to an individual employee at company housing under a corporate contract, it is most reliable to display both the “Company Name” and the “Employee’s Personal Name” on the mailbox. If there is a rule that only the company name can be displayed on the mailbox, instruct the employee to add “c/o [Company Name] (〇〇株式会社様方)” at the end of their registered address for utility contracts and online shopping.
Conclusion: Make Them Aware of the Delivery System Differences on “Day One”
Japan’s strict postal rule that “mail is not delivered unless the name is written” is an unexpected hurdle for many foreigners. To prevent the loss of critical documents directly tied to their livelihood—such as initial utility bills and notifications from the municipal office regarding residence cards—HR managers must incorporate “labeling the mailbox and registering with the post office” as a mandatory task during the move-in orientation.
