Understand how your insurance card worksQuick conclusion
Japanese public health insurance covers most illness and injury treatment at 30 percent of cost, but a specific list of things fall entirely outside coverage: normal childbirth, cosmetic treatment, most vision correction, many vaccines, health checkups, and orthodontics. None of these are surprises if you ask "is this covered by insurance?" before any test or treatment that sounds optional or elective - clinics will tell you directly, and many will give a written estimate on request.
What typically is not covered
| Item | Typical situation | Approximate cost if uncovered |
|---|---|---|
| Normal childbirth | Not covered, but a lump-sum allowance from your insurer offsets much of it | Often 400,000-600,000 yen total, largely offset by the allowance |
| Health checkups | Basic ones are often free via employer/municipality; comprehensive private ones are not covered | 20,000-100,000+ yen for private ningen dock checkups |
| Cosmetic treatment/surgery | Not covered | Fully private pricing |
| Orthodontics, most dental implants | Not covered | Often several hundred thousand yen |
| Vision correction (glasses, contacts, LASIK) | Not covered; eye disease treatment is covered | Fully private pricing |
| Travel and some optional vaccines | Not covered unless part of the national program | A few thousand to over 10,000 yen per dose |
| Private hospital room fee | The room upgrade itself is not covered even though your treatment is | A few thousand to tens of thousands of yen per night |
Why this catches people off guard
The 30 percent copay from your insurance card applies specifically to treatment classified as medically necessary under the national fee schedule. Anything classified as elective, preventive-but-optional, or cosmetic sits outside that schedule entirely, so there is no partial coverage - you pay the clinic's own private price, and prices can vary between clinics for the same service.
The one question that avoids surprise bills
Before any test, vaccine, or treatment that feels optional, ask directly: "Is this covered by insurance, and what will it cost me?" (保険適用ですか、自己負担はいくらですか). Reception staff answer this constantly and can usually quote a number on the spot. This single habit prevents the most common source of unexpected medical bills for foreign residents.
Two costs worth planning ahead for
- Childbirth. Even though normal delivery is not insurance-covered, Japan's childbirth lump-sum allowance covers a large share of typical costs, and complications requiring medical intervention are insured. Our pregnancy and childbirth guide covers the full cost picture and what to register in advance.
- Health checkups. Employer and municipal checkups are usually free or low-cost by law or subsidy; only the upgraded private versions cost real money. See annual health checkups in Japan for the difference.
Getting some money back
If your uncovered medical costs (plus certain covered copayments) exceed a yearly threshold, Japan's medical expense tax deduction can reduce your taxable income - keep every receipt, covered or not, through the year. If you are weighing whether private supplemental insurance is worth adding on top of public coverage, insurance basics for foreign residents compares the common options.
This is general information, not medical or tax advice. Coverage rules can change and depend on your specific insurer and treatment - confirm with your clinic, insurer, or a tax professional before assuming a cost is or is not covered.
Before you apply

- ✓Confirm whether a vaccine is part of the national program or private
- ✓Check if a private insurance policy could help with excluded costs
- ✓Keep all receipts for possible high-cost medical expense tax deduction
- ✓Ask specifically whether childbirth costs are covered or subsidized
FAQ
Is childbirth covered by health insurance in Japan?
Normal, uncomplicated childbirth is generally not covered by public health insurance and is billed at full cost, though a lump-sum childbirth allowance (出産育児一時金) from your insurer offsets a large part of it. Complications requiring medical treatment, such as a cesarean section, are usually covered at the standard 30 percent rate. Details are in our pregnancy and childbirth guide.
Are vaccines covered by insurance in Japan?
Vaccines included in Japan's national immunization program are often free or low-cost, especially for children, while travel vaccines, some adult vaccines, and optional vaccines are usually paid in full privately. Ask the clinic which category applies before your appointment.
How much does a health checkup cost if it is not covered?
A basic employer or municipal checkup is often free or low-cost, but comprehensive private checkups (ningen dock) with extra imaging and tests can cost from roughly 20,000 to over 100,000 yen depending on scope, since these are not classified as insurance-covered treatment.
Can I get money back for high medical costs through tax deductions?
Japan's medical expense deduction (医療費控除) lets you deduct qualifying medical costs above a threshold (commonly around 100,000 yen per year, adjusted by income) when filing your annual tax return. Keep all receipts, including some non-covered costs, and check current thresholds with a tax office or accountant.
Should I get private insurance to cover these gaps?
Some foreign residents add private insurance for cases like childbirth, dental work, or income protection during illness. Compare what your public insurance already handles before buying anything - our insurance basics guide walks through common overlaps and what is actually worth paying for.
