Previous-year income
Municipal premium notices commonly depend on income from the previous year. New arrivals and low-income users may still need income reporting or city-office confirmation.

What drives NHI cost?
Household members
NHI is often billed at the household level. The head of household can receive the bill even when multiple members are insured.
Age 40 to 64
Many city pages separate a long-term care insurance portion for people in this age range, so the same income can produce a different bill.
City rules
The final premium is local. Tokyo wards, major cities, and regional municipalities can use different rates, caps, payment schedules, and reduction procedures.
Choose the NHI path by resident status
New arrival with address registration
Start with residence card, registered address, and municipality procedure. Use address registration checklist, My Number checklist, and bank setup before relying on direct-debit or payment-slip timing.
Working holiday or temporary accommodation
If your first stay is a hotel or temporary room, keep travel medical insurance active and confirm the registration route once you settle. Use working holiday health insurance and working holiday budget before assuming NHI starts immediately.
After resignation or job loss
When workplace insurance ends, compare NHI, voluntary continuation, dependent route, and new employer coverage. Use resignation and unemployment insurance plus general health insurance calculator to plan the switch.
Age 40 to 64 or family household
Budget for care-insurance and household effects before judging the bill. Use payslip deduction calculator when comparing employer insurance and municipal NHI.
Leaving Japan or moving out
Before departure, handle moving-out notification, NHI withdrawal, card return, final premium reserve, and mail follow-up. Use NHI leaving checklist and leaving Japan checklist.
High-intent checklist before the bill arrives
- Confirm whether you are on workplace health insurance. If yes, do not assume municipal NHI also applies.
- If you leave a job, compare voluntary continuation, dependent coverage, new workplace insurance, and municipal NHI quickly, then check Hello Work and visa-notification timing if you are job-searching.
- Register your address and confirm the ward/city office handling your NHI procedure.
- Check whether your previous-year income was reported. Missing income data can delay or distort premium calculation.
- Plan the June-to-March payment rhythm used by some cities, plus mid-year recalculation after moving or changing status.
- Prepare payment route: bank debit, payment slip, convenience-store payment, or the method your municipality supports.
- If leaving Japan, file moving-out procedures and NHI withdrawal instead of letting bills continue after departure.

FAQ for NHI cost planning
Why did my first NHI bill look different from the estimate?
Your municipality may use local rates, reductions, caps, prior-year income records, household facts, and mid-year enrollment timing. Treat this calculator as a reserve signal.
Do I need NHI if I have travel insurance?
Travel insurance and municipal public insurance are different layers. If you become a registered resident and are not covered by workplace insurance, confirm the public insurance procedure with the municipality.
What if I am 40 to 64?
Many municipal explanations add a long-term care insurance portion for people between 40 and 64. Budget extra and check the city notice.
What if I leave Japan before the year ends?
Do the moving-out and NHI withdrawal procedure before departure. Otherwise, bills or refunds may be delayed and hard to resolve from overseas.
