How to Enroll in National Health Insurance in Japan
Foreign residents who are not covered by employer-provided health insurance typically need to enroll in National Health Insurance (NHI / 国民健康保険) within 14 days of registering their address. NHI covers approximately 70% of medical costs at hospitals and clinics across Japan, making it one of the most important registrations after arriving.

Step-by-Step Enrollment Process
Step 1: Complete Resident Registration
You need to register your address first. NHI enrollment can often be done at the same visit.
Step 2: Visit the Insurance Counter
Bring your Residence Card (在留カード), passport, and My Number notification if available. Some offices provide multilingual forms.
Step 3: Submit the Application
Fill out the NHI enrollment form. Staff will verify your visa status and residency. If you have dependents, include their information.
Step 4: Receive Your NHI Card
The insurance card is usually mailed to your registered address. Present it at every medical visit to receive the 70% coverage benefit.
Step 5: Set Up Premium Payments
Payment slips arrive monthly. Options include convenience store payment, bank transfer, or automatic deduction.

Q: What if I enroll late — do I owe back premiums?
Yes. Premiums are calculated from the date you became eligible, not the date you applied. Late enrollment means you may owe several months of back premiums at once.
Q: Can I use NHI at any hospital?
NHI is accepted at virtually all hospitals and clinics in Japan. There is no network restriction like some private insurance systems.
Q: What happens if I get employer insurance later?
You need to cancel your NHI at the city office once employer insurance (shakai hoken) begins. Failing to cancel results in double billing.
