💴 Kenpo Voluntary Coverage: Pay by Sept 10

❓ What's happening?

On August 27, 2026, the Japan Health Insurance Association (Kyokai Kenpo) reminded people enrolled as "voluntary continuation" (nini keizoku) insured persons that the premium for September is due on Thursday, September 10. Payment slips were mailed on August 27, and anyone who has not yet paid is asked to do so by the deadline. Voluntary continuation lets you keep the health insurance you had at your company for up to two years after you leave the job and lose your insured status. The big difference from being employed is how the premium is paid: while working, the cost is split with your employer and deducted from your salary automatically. Under voluntary continuation you pay the full amount yourself, and there is no payroll deduction — you must pay it every month on your own. The deadline is the 10th of each month in principle (the next business day if the 10th falls on a weekend or holiday), which is September 10 this month. The critical part: if payment is not made by the deadline, you lose your voluntary continuation status the following day. Treatment received after that is paid entirely out of pocket in principle, and you must take separate steps such as joining National Health Insurance. Because a simple oversight can leave you uninsured, the Association issues this reminder every month.

👥 Who is affected?

• ●Spouses and children covered as dependents under a voluntary continuation enrollee

🌏 Impact on foreign residents

When a foreign resident leaves a job in Japan because of a career move or the end of a contract, they must decide what to do about health insurance. If you choose voluntary continuation, your former company's coverage continues for up to two years on the same terms as for Japanese nationals. However, the payment slip arrives in Japanese, and the payment instructions at banks and convenience stores are in Japanese too. If you set aside the envelope as "mail I don't understand," you lose your status the day after September 10, and any treatment after that must be paid in full at the counter. Even if you hold a My Number health insurance card, no valid coverage will show once your status is gone. Be especially careful if a trip home or a business trip overlaps with the due date — that is when payments get missed. Setting up direct debit from a bank account keeps payments running while you are abroad. Also, whether you have properly met public obligations such as insurance premiums is something immigration checks when you renew or change your status of residence. Keep on top of the deadline so a short lapse does not affect later procedures.
