If you are planning to leave Japan, cancelling your National Health Insurance (NHI) is one of the most important administrative tasks you need to complete before you go. Many foreign residents are unsure exactly when to cancel, what documents to bring, or what happens if they forget. This guide walks you through the entire process of how to cancel national health insurance in Japan when leaving, so you can depart with everything properly sorted.
Do You Need to Cancel NHI When Leaving Japan?
Yes — in most cases, you must cancel your National Health Insurance enrollment when you leave Japan and deregister your address. NHI is tied to your residency registration (the juuminhyo). Once you complete your departure procedures at your local ward or city office, your NHI enrollment should be cancelled at the same time. However, it is essential to handle this actively and not assume it happens automatically without your involvement.
If you do not cancel properly, you may continue to receive premium bills even after you have left the country, and settling those unpaid bills can cause complications if you ever return to Japan in the future.
When Should You Cancel?
The standard timing is on the day you complete your "move-out" notification (転出届, tenshutsutodoke) at your local municipal office — ideally within two weeks before your actual departure date. You can submit this notification up to two weeks before you leave, which is the recommended approach so your paperwork is in order before your flight.
Do not leave this until after you have already departed Japan, as that makes the process significantly more complicated and may require someone with power of attorney to act on your behalf.
Step-by-Step: How to Cancel National Health Insurance in Japan When Leaving
Step 1: Go to Your Local Municipal Office
Visit the ward office (kuyakusho), city hall (shiyakusho), or town office (chousho) where you are registered. Look for the Residents Section (juumin-ka) or the National Health Insurance Section (kokumin kenko hoken-ka). These are usually on the same floor or nearby.
Step 2: Submit Your Move-Out Notification
Tell the staff that you are leaving Japan permanently (or for an extended period that ends your residency). You will fill in a move-out notification form. This triggers the cancellation of your residency record and, along with it, your NHI enrollment.
Step 3: Return Your NHI Card
You will be asked to hand back your National Health Insurance card (hoken-sho). Make sure you bring it with you. If you have lost it, inform the staff — do not simply not mention it.
Step 4: Settle Any Outstanding Premiums
The office will calculate any remaining NHI premiums you owe up to your cancellation date. You may be asked to pay these on the spot or receive a final bill. It is a good idea to check in advance whether you have any unpaid premiums so there are no surprises. Conversely, if you have overpaid (for example, through automatic bank transfer), you are entitled to a refund — ask the staff about this.
Step 5: Receive Your Cancellation Certificate if Needed
In some cases, you may want to request a document confirming your NHI cancellation. This is not always mandatory, but it can be useful as proof should any billing issues arise later.
Documents to Bring
- Your Residence Card (zairyu card)
- Your National Health Insurance card (hoken-sho)
- Your My Number card or My Number notification letter (if you have one)
- Your passport (recommended to bring as additional ID)
- Your flight details or proof of departure (some offices ask for this)
Requirements can vary slightly by municipality, so it is worth calling ahead or checking your local office's official website to confirm exactly what they need. This is general guidance — always verify the latest requirements directly with your local office.

What About Company Health Insurance (Shakai Hoken)?
If you are enrolled in employer-based health insurance (shakai hoken) rather than NHI, the cancellation process is different. Your employer typically handles the disenrollment paperwork when your employment ends. Check with your HR or payroll department well in advance of your departure date. This guide focuses on NHI, which covers those who are self-employed, part-time workers, students, or not covered by an employer's scheme.
Common Worries — Answered
"What if I already left Japan without cancelling?"
If you have already departed, contact your local municipal office by phone or email, or ask a trusted person in Japan to act on your behalf with a written power of attorney (inin-jo). The sooner you resolve this, the better, especially if you plan to return to Japan.
"Will unpaid NHI premiums affect my next visa?"
Outstanding debts to the municipality can potentially affect your re-entry or future visa applications. It is strongly advisable to clear all balances before leaving. For specific immigration implications, consult a qualified immigration lawyer or the relevant authorities.
"Do I get a refund if I paid too much?"
Yes, overpayments are generally refundable. Bring your Japanese bank account details to the office if you want the refund deposited directly, or arrange to receive it by post. Confirm the refund process with your local office, as procedures vary.

Summary: Cancelling NHI When Leaving Japan
Cancelling your national health insurance in Japan when leaving does not have to be stressful. The key is to act early — visit your local municipal office up to two weeks before your departure, bring your documents, return your NHI card, and settle any outstanding premiums. Doing this at the same time as your move-out notification means you can tick off several departure tasks in a single visit.
Departure admin can feel overwhelming, especially with a language barrier, but Japanese municipal offices are used to helping foreign residents and most have multilingual support or at least simple forms. Take it one step at a time, and you will have everything wrapped up smoothly before your flight. Safe travels.
