Who has to join public health insurance in Japan?

Every foreigner who is registered as a resident of a Japanese town must be in a public health insurance scheme, and in practice that means anyone whose stay is longer than three months. Nerima City’s 2026 guidebook says all people who live in Japan must enrol, and that an individual cannot decide of their own free will to join or to leave. The Tokyo Metropolitan Government’s English medical guide gives the three-month rule, and GOV.UK tells British nationals that a visa valid for more than 90 days means enrolment in NHI or employee insurance.

Two rules matter from the first day. First, the timing: you have 14 days after moving in to enrol, and if you are late, premiums are charged back to the date you should have joined, while bills from the gap are yours in full unless the delay was unavoidable. Second, the permanence: Nerima City states that you cannot leave NHI because you already hold international student insurance, a life insurance plan with medical benefits or traveller’s accident insurance, and you cannot leave because premiums feel high or you never see a doctor. If you are a resident, a private or international plan sits on top of NHI; it does not replace it. For how Japan’s system compares with 29 others, see healthcare systems by country.

NHI or employee health insurance: what is the difference?

Employee health insurance is run for people with a job in Japan and the employer pays part of the premium, while National Health Insurance is run by your town for everyone else and you pay the whole premium yourself. Both give the same basic deal at the clinic: you show your card, pay your share and the scheme pays the rest. People who are in an employees’ scheme, or are eligible for one, cannot join NHI.

When you change from one to the other, act within 14 days. If you take a job with employee insurance but forget to leave NHI, Nerima City warns that you will be a member of two schemes and billed twice. If you leave a job, you either continue the employee scheme voluntarily or join NHI; the voluntary route has a short 20-day window. Freelancers and remote workers paid from abroad who hold a resident status and no employee scheme belong in NHI, which our health insurance guide for freelancers abroad places in a wider context.

How much does National Health Insurance cost in Japan in 2026?

NHI costs between about ¥85,000 and ¥1,130,000 a year for a single person aged 40–64 in Nerima City (Tokyo) in fiscal 2026, before any low-income reduction, because the premium is a percentage of last year’s income plus a fixed amount per person, with caps. Every town sets its own rates, so take Nerima as one official example, not a national price.

The Nerima guidebook splits the premium into four parts. Each takes a percentage of your income base, which is last year’s total net income minus a ¥430,000 basic exemption, and adds an amount per insured person. The care portion applies only to members aged 40 to 64; from 65 the long-term care premium is billed separately. The child and childcare support portion is new in fiscal 2026.

Calculated with the published Nerima City formula for April 2026 to March 2027, before rounding. Low-income households have the per-capita part cut by 70, 50 or 20 percent automatically, but only if their income has been reported.

Practical points come with the bill. The year runs from April to March and is paid in ten instalments from June to March, so April and May show no payment. You pay from the month you became eligible, not from the day you filled in the form, and in whole months. If you lived outside Japan on 1 January, the city sends a simplified income report; the guide does not say how income earned abroad is treated, so ask the NHI counter at your city office. The bill goes to the head of household even if that person is not in NHI, and it covers every NHI member in the home.

What do you pay at the doctor in Japan with public insurance?

With NHI or employee insurance you pay 30% of the bill at the counter if you are between school age and 69, and the scheme pays the other 70%. Children before school age pay 20%. At 70 to 74 the share falls to 20% unless your household has higher income, and at 75 you move to the separate system for older senior citizens.

Nerima City says the majority of medical facilities are partnered with NHI. If you visit one that is not, or you arrive without your card, you pay the full bill and claim later where the rules allow. Show your Myna health insurance certificate (a My Number card with the health function switched on) or the paper qualification certificate the city issues if you do not have one. Using someone else’s card is reported to the police.

How does the high-cost medical expense benefit cap your bills?

The high-cost medical expense benefit caps what a household pays in co-payments each month, so a large hospital bill costs you a few tens of thousands of yen to a few hundred thousand rather than 30% of the total. The caps rose on 1 August 2026, and Minato City says they will change again in August 2027. Bills are counted per calendar month; private-room charges, meals and treatment outside the scheme do not count.

A worked figure shows the effect. A month in hospital with a total bill of ¥1,000,000 would cost ¥300,000 at 30%. In the middle income band the cap is ¥85,800 plus 1% of ¥714,000, so you pay about ¥92,940 (our calculation), plus meals and any private-room charge. Ask the city for a ceiling-amount certificate before a planned stay, or use your Myna card, and the hospital charges only the capped amount. Otherwise you pay 30% and the refund follows months later. Nerima’s guidebook, printed before August, still shows the older caps (for example ¥80,100 plus 1% above ¥267,000 in the middle band); the newer Minato figures are the ones in force.

What does Japanese public health insurance leave out?

NHI leaves out general check-ups, vaccinations, normal pregnancy and delivery, cosmetic treatment and private-room charges, and it pays for treatment abroad only at Japanese rates. Private or international cover can fill some of these gaps.

The overseas rule matters most for people who travel. If you fall ill in Thailand or Europe while you are an NHI member, you pay the local bill, bring forms filled in by the hospital and Japanese translations, and claim after you are back. The refund is worked out on what the same care would cost in Japan, so a high foreign bill can leave a large balance. A long-term international plan pays on its own terms in every Zone 1 country; our expat health insurance guide explains how such plans work.

What health insurance does the Japan digital nomad visa need?

The Japan digital nomad status needs private medical insurance that covers death, injury and illness during the stay, with at least ¥10 million for medical treatment of injury and illness, because nomads cannot join Japanese public insurance. The Immigration Services Agency also asks for an annual income of at least ¥10 million and allows a stay of six months with no extension. No residence card is issued.

Read the death clause carefully: the agency’s Q&A says the policy must include transport of the body or an insurance payment on death. A health plan may list medical transport home but not repatriation of remains, so check the wording of whatever policy you plan to show. Timing matters too: the documents go in with the application for a certificate of eligibility, before you travel, so the policy must already exist and must run for the planned stay. Our digital nomad health insurance guide covers the travel-versus-long-term question, and digital nomad visas by country sets Japan beside other routes.

What insurance does the long-stay visa for sightseeing and recreation need?

The long-stay status for sightseeing and recreation, the closest thing Japan has to a retirement visa, needs private medical insurance for the whole planned stay that covers death, injury and illness in Japan, and the agency page we read sets no minimum sum. Holders are excluded from NHI. The stay is limited to one year, and an Embassy of Japan checklist asks for savings of more than ¥30 million and an applicant aged 18 or over.

Because there is no stated minimum, the officer reviewing your file decides whether your policy is adequate. A policy that names you, states Japan, shows dates covering the full stay and lists death, injury and illness benefits is the safest document. Japan has no retirement visa in the sense of Thailand or Portugal; for countries where retirees can settle, compare retirement visas by country, and for what each visa demands of your insurance, see visa health insurance requirements by country.

Can visitors to Japan use National Health Insurance?

No: people with temporary visitor status are excluded from NHI, so a tourist or business visitor pays the full bill unless a private policy pays it. The Japan Tourism Agency strongly encourages private medical insurance with adequate cover and notes that it can be bought before the trip or after arrival. The Tokyo Metropolitan Government adds that visitors who leave medical bills unpaid may be refused entry in future.

The two cost examples on the official tourism and Tokyo pages, both from an insurer’s assistance company, show why: about ¥7.5 million for a bicycle collision that caused a collapsed lung and broken ribs (surgery, 19 days in hospital, a doctor escort and a business-class flight home) and about ¥10 million for a heart attack with surgery and 45 days in hospital. If you visit Japan from a base elsewhere in Asia, Care Expat World covers Japan as part of Zone 1, subject to its terms.

How does private health insurance in Japan work for foreigners?

Private health insurance in Japan works in two very different ways for foreigners: for residents it is optional extra cover on top of compulsory NHI or employee insurance, and for nomads, long-stay tourists and visitors it is the only cover they have. That difference decides what to buy.

Residents consider private cover for four reasons: private rooms and the hospitals they prefer, items NHI leaves out such as check-ups and some dental work, cover while travelling outside Japan, and one policy that keeps running if they move on to another country. Japanese insurers sell medical policies to residents; we found no official price list. Before you buy, ask in writing: does it pay the bill or a fixed cash amount per day in hospital, does it pay outside Japan, is there an age at which it stops, and how are pre-existing conditions treated?

Non-residents need a policy that would work without any public scheme behind it. For a nomad, that means meeting the ¥10 million treatment rule and the death clause. For a long-stay visitor, it means dates and benefits matching the stay. Travel policies are built for this; long-term international plans can be, if their wording and start date fit. People with medical history should read how pre-existing conditions are handled before applying anywhere.

Where does Care Expat World fit for expats in Japan?

Care Expat World fits in two places in Japan: as the private top-up and worldwide cover for residents who must still join NHI, and, for nomads and long-stay visitors, only as a policy whose fit with the visa wording is unconfirmed: the documents show no death or repatriation-of-remains benefit, the immigration officer decides, and we make no claim that it is accepted. Japan is in Zone 1, which covers the whole world except the USA, China and Singapore; in those three it pays only emergencies, for trips of up to 42 days, and never in your own home country.

For residents, the plan is an addition. You keep paying NHI, and you hold the plan for private hospitals, travel across Zone 1 and, on Comfort and Premium, dental care, check-ups and glasses. The insurer’s terms say it cannot guarantee that the contract satisfies any local compulsory insurance rule, which is one more reason not to treat it as a substitute. How the plan’s refunds work when NHI has already paid its 70% is not stated in the documents we read, so ask Care Concept in writing before you rely on it for bills in Japan.

For nomads and long-stay visitors, timing and wording decide. Cover always starts on the 1st of a month, at most four months ahead and never before you cross the border, so it cannot be bought from home to show with a certificate-of-eligibility application. It can only help someone who already lives abroad and is already insured, for example an American nomad based in Thailand. Even then, the plan has a 12-month minimum term while the nomad stay lasts six months, and the documents we read list medically advised transport home but no repatriation-of-remains benefit. Ask Care Concept in writing for the treatment sum and the death benefit; if the answer does not match the agency’s wording, use travel or visa insurance for the application and keep long-term cover for living abroad before and after Japan. The full terms are on the plan details page.

Three general rules apply too. Prior health insurance that ended no more than 12 months before the start is a condition, and a gap brings a 31-day waiting period; does Medicare, the NHS or Japanese NHI count as that prior insurance? The documents don’t confirm this; ask Care Concept in writing. The documents promise no direct billing with Japanese hospitals, so plan to pay and claim. And home-country cover exists only for EU or Schengen home countries, which leaves Americans, Britons and Japanese citizens without it; see international health insurance with home-country cover.

Health insurance in Japan for Americans vs Britons: what is different?

Little is different once you live in Japan: Americans and Britons both join NHI or employee insurance on the same terms as other residents, and neither country has a health agreement that replaces it. The differences are at home: Medicare generally does not pay outside the United States, and GOV.UK says Japan has no reciprocal health agreement with the UK.

Residents also pay into the National Pension: Yokohama City says everyone aged 20 to under 60 who lives in Japan must join, and the Japan Pension Service sets the fiscal 2026 contribution at ¥17,920 a month. Americans should settle the Medicare Part B question before moving; see health insurance for Americans living abroad. Britons should read health insurance for UK expats for the NHS side. Canadians and Australians face similar questions about home cover; see Canadians living abroad and Australians living overseas.

What does health cover in Japan cost? 2026 comparison

A single resident aged 40–64 in Nerima City pays about ¥85,000 to ¥1,130,000 a year for NHI depending on income, Japanese private policies have no official price, and Care Expat World in Zone 1 starts from €120 a month at 45–49 and €325 at 60–64. The yen and euro figures are shown separately; convert at the day’s rate.

Over a year at 60–64, Basic with the €3,600 deductible costs €3,900 in premiums and Comfort with €1,200 costs €7,860; in a heavy year add the deductible, for €7,500 and €9,060. A resident pays this on top of the NHI premium. At 45–49 the same two levels cost €1,440 and €3,660 a year. Prices for every age are on what international health insurance costs.

Checklist: health cover for your move to Japan

• Residence status checked: does it make you a mid- to long-term resident (NHI or employee insurance) or not (private cover only)?
• Residents: NHI enrolment at the city or ward office within 14 days of moving in, or confirmation that the employer has enrolled you
• My Number card with the health function activated, or the paper qualification certificate, carried to every visit
• Simplified income report returned if you lived outside Japan on 1 January
• National Pension enrolment if you are 20 to under 60, or proof of exemption
• Ceiling-amount certificate requested before any planned hospital stay
• Digital nomads: policy with at least ¥10 million for treatment, a death benefit (body transport or payment), and the agency’s coverage form filled in
• Long-stay visitors: policy dates matching the whole stay and benefits for death, injury and illness
• International plan: start date on a 1st after arrival, prior-insurance and NHI-coordination questions sent to Care Concept in writing
• Separate cover for trips to the US or UK (no home-country cover for Americans or Britons)
• Americans: Medicare Part B decision recorded before the move
• Before leaving Japan: moving-out procedure done so NHI premiums stop

Worked example: an American aged 62 and a Briton aged 52

Linda, 62, from Oregon, moves to Tokyo with her Japanese husband on a spouse visa and rents in Nerima. She is a mid- to long-term resident, so she enrols in NHI at the ward office within 14 days; private cover is not an alternative. Her pension income gives her a total net income of about ¥2,000,000 for the previous year, so on the Nerima formula her yearly premium is about ¥289,130 (our calculation), paid in ten instalments; because she lived in Oregon on 1 January, the ward office first sends her a simplified income report and decides which income counts. At 62 she is past the National Pension age range. At the doctor she pays 30%, and a ¥1,000,000 hospital month would cost her at most ¥61,500 if her household’s income base stays at or below ¥2.10 million (about ¥92,940 in the middle band). She adds Care Expat World Comfort with a €1,200 deductible from the 1st of the month after she arrives: €655 a month, or €7,860 for the 12-month minimum term, for private rooms, dental care and trips across Asia and Europe. Before she relies on it in Tokyo, she asks Care Concept in writing how claims work when NHI has already paid. On visits to Oregon the plan does not cover her, because the USA is her home country, and Medicare does not pay in Japan.

Graham, 52, from Leeds, is a software contractor earning well above ¥10 million a year. He already lives in Chiang Mai with Care Expat World Basic at the €3,600 deductible, €140 a month (€1,680 a year), and wants six months in Japan on the digital nomad status. He cannot join NHI, so his visa file needs private cover of at least ¥10 million for treatment plus a death benefit. He asks Care Concept for a written statement of the treatment sum and any repatriation-of-remains benefit; the immigration officer, not the insurer, decides whether that is enough. Because the plan’s documents do not show a death benefit, he also prices a six-month travel policy that meets the agency wording, and he keeps his long-term plan for Thailand and for life after Japan. Trips to the UK stay outside the plan throughout.

What if you are 65 or older?

At 65 or older the public route stays open in Japan, because residents remain in NHI until 75 and then move to the Medical Care System for Older Senior Citizens, but the private layer narrows. From 65 the long-term care premium is billed separately from NHI, and at 70 to 74 your share at the clinic drops to 20% unless your household income is higher. For Care Expat World, the last possible start date is 1 December of the year you turn 64. If you are close to that limit, the year you apply decides what is open to you; see expat health insurance over 65, age limits on international health insurance and expat health insurance for retirees.

Health insurance in Japan vs other Asian countries

Japan stands out in Asia because public insurance is compulsory for foreign residents and cannot be replaced with a private policy; the guides below set out the rules in other Asian countries. Japan, Thailand, Vietnam and the Philippines are in Zone 1 of Care Expat World; Singapore is not.

Japan sits in Zone 1: the whole world apart from the USA, China and Singapore, with stays in those three limited to emergencies on trips of up to 42 days; Americans are not covered in the USA at all, because it is their home country. The terms pay at home only when the home country belongs to the EU or Schengen area, which leaves Americans without cover in the USA and Britons without cover in the UK. For residents of Japan the plan is extra cover on top of compulsory public insurance, and nothing here claims that the Immigration Services Agency or an embassy will accept it for a visa. Already 65 or older in the year cover would start? This plan is closed to you; we are preparing a comparison of plans without an entry-age limit. Prices for every age are on the Care Expat World overview.

Premium rates differ by municipality; Nerima City is used as one official example. Nerima’s guidebook still prints the high-cost caps in force before August 2026; we use Minato City’s newer figures. We found no official minimum insurance sum for the long-stay visa, no official statement on how income earned abroad counts in a first-year NHI premium, and no official text yet on the planned unpaid-premium rule. Check with your city office and the Immigration Services Agency before you rely on a figure.
