Show your health insurance card at the reception desk of any clinic or hospital in Japan before your appointment, and you will pay roughly 30 percent of the covered cost instead of the full price. The card does not cover everything - cosmetic treatment, normal childbirth, and some tests are excluded - so ask reception for an estimate if you are unsure whether something is covered.
How to actually use it at a clinic
1. Check in at reception first. Hand over your insurance card before filling out any forms - most clinics ask for it immediately, sometimes alongside a "first visit" questionnaire. 2. New patient forms. Expect to write your name, address, symptoms, and medical history, often in Japanese only. Bringing a translation app or writing key symptoms in advance helps. 3. After treatment, pay at the counter. The bill already reflects your 30 percent share; you do not need to file anything yourself for standard treatment. 4. Keep the receipt (領収書). It itemizes what was covered - useful for tax deduction claims (medical expense deduction) if your annual costs are high, and for your own records.
What your card does and does not cover
| Covered at ~30% cost | Usually not covered |
|---|---|
| Illness and injury treatment | Normal (non-complicated) childbirth |
| Prescribed medicine at pharmacies | Health checkups and screenings (often billed separately, see above) |
| Surgery and hospitalization for illness | Cosmetic surgery and treatment |
| Basic dental treatment | Orthodontics, most dental implants |
| Physical therapy for injury | Vaccinations outside the national program, vision correction, some fertility treatment |

If you forget your card
Clinics will usually still see you, but you will be billed the full 100 percent amount that day. Ask reception whether you can return with your card within a set number of days for a refund of the difference - policies differ by clinic, and some require a specific return window. Always ask before you leave, and keep the receipt either way.
Choosing where to go
Insurance works identically at every clinic and hospital nationwide, so choose based on language support and convenience rather than network restrictions. If Japanese is a barrier, our guide to finding an English-speaking clinic explains where to look. For prescriptions after your visit, see how pharmacies and prescriptions work in Japan.
Keeping your coverage valid
Your insurance enrollment is tied to your residence status and registered address. If you change jobs, move, or your residence card is close to expiring, your coverage can lapse without you realizing it - confirm your status at your city/ward office or with your employer's HR when any of these change. The basics of how the system is structured are covered in Japanese health insurance explained.
This is general information. Confirm your specific coverage and costs with the clinic or your insurer, since exact percentages and exclusions can depend on your age, income, and insurance type.

FAQ
What percentage of medical costs does insurance cover in Japan?
For most working-age adults enrolled in Japanese health insurance (National Health Insurance or employer-based insurance), you pay 30 percent of the covered cost at the counter, and insurance covers the remaining 70 percent. Children and people over 70 often pay a lower percentage.
What happens if I forget my insurance card?
Most clinics will still treat you but will bill you the full 100 percent cost at that visit. You can usually bring your card within the following days (rules vary by clinic) and get reimbursed for the difference, so ask reception whether this is possible before you leave.
Can I use my insurance card at any clinic in Japan?
Yes. Japanese public health insurance is accepted at essentially all clinics and hospitals nationwide - there is no network restriction like private insurance in some other countries. You do not need a referral for most first visits to a clinic, though large hospitals may require one or charge an extra fee without it.
Does the insurance card cover dental and vision?
Basic dental treatment is covered at the same 30 percent rate. Routine eye exams and glasses are generally not covered, though eye disease treatment is. Cosmetic dental work, orthodontics, and vision correction surgery are also outside coverage - see the details in what is not covered by insurance.
What should I do if my insurance card is expiring soon?
National Health Insurance cards are usually reissued yearly and mailed to your registered address; employer insurance cards renew with your enrollment. If your residence card is also close to expiring, renew that first since your insurance status is tied to your residence status - check with your city/ward office if you are unsure.
