Going to a Hospital in Japan: Insurance, Costs and What to Say

A fever that arrives on a Sunday night. A tooth that has been throbbing for a week. A back that gave out while lifting boxes at the warehouse. Sooner or later every resident of Japan needs a doctor, and the first visit is almost always the hardest — not because the medicine is unfamiliar, but because the system wrapped around it is.

Japan's medical care is genuinely cheap and genuinely good, and it is open to you on exactly the same terms as your Japanese colleagues. What it assumes, quietly, is that you already know a few unwritten rules: that you start small rather than big, that a single sheet of paper called a referral letter can save you thousands of yen, and that the frightening number on a hospital bill is very often not the number you actually end up paying.

Everything below reflects the rules in force as of August 2026, including the revision to the high-cost medical expense benefit that took effect on 1 August 2026 and the end of the grace period for old paper insurance cards on 31 July 2026. Amounts set by national rules can change, so treat the figures as a guide and confirm with the institution or your insurer.

Start at a clinic, not at a hospital

Japanese law draws a hard line between two kinds of medical institution. Under Article 1-5 of the Medical Care Act, a "hospital" is a facility with beds for twenty or more inpatients. A "clinic" either has no beds at all or has beds for nineteen patients or fewer. That single number explains almost everything about how you should use the system.

A clinic is usually one doctor, a receptionist, a nurse or two, and a specialty painted on the sign outside — internal medicine, orthopaedics, ear nose and throat, dermatology, paediatrics, gynaecology. You generally walk in during posted hours without an appointment. You wait perhaps thirty to sixty minutes rather than half a day. And for the overwhelming majority of what sends people to a doctor — fever, a cough that will not clear, stomach trouble, a sprained ankle, a rash, a persistent headache — the clinic is not a downgrade. It is the correct level of care.

Large hospitals are built around referred patients, inpatients, surgery and advanced diagnostics. Turning up at one with a common cold means a long wait among people who are seriously unwell, and, at many of them, an extra charge on top of your normal payment.

The habit worth building now, while you are healthy: find the clinic closest to your home or your workplace, note its hours and its closed days, and go there first every time. Over a couple of visits the doctor accumulates a record of you — your allergies, your medications, your baseline. That record is what makes a referral letter meaningful when you eventually need one.

The referral letter, and what it costs to skip it

If a clinic doctor decides your case needs a specialist, imaging or admission, they write a referral letter addressed to a specific hospital department. It is written as an insured service, so your share of it is small, and it does two jobs at once: it carries your symptoms, test results and medication list across so the hospital does not start from zero, and it exempts you from the extra charge described below.

Since 1 October 2022, national rules require certain hospitals to collect a "special charge" from patients who arrive without one. The charge sits on top of your normal percentage payment, and no insurance covers it. Three categories of hospital must collect it: designated advanced-treatment hospitals, which in practice means most university hospitals; regional medical support hospitals with 200 or more general beds; and referral-focused medical institutions with 200 or more general beds.

The Ministry of Health, Labour and Welfare sets only the floor. Each hospital chooses its own figure at or above that floor, consumption tax included, and 7,700 yen is a very common setting for a first visit.

There are real exemptions. Hospitals are prohibited from charging emergency patients, recipients of nationally funded medical care programmes, and certain other protected groups. They may also waive it for patients referred internally from another department, patients sent for detailed testing after a health check or cancer screening, patients admitted straight from the outpatient visit, and patients treated for a work injury, a public-service duty injury, a traffic accident or on a self-pay basis, patients affected by a disaster, and clinical trial participants.

The 30 percent you pay and the 70 percent you never see

Once you are enrolled in public medical insurance — employees' health insurance through your company, or National Health Insurance through your city — you pay only a fixed share of the price at the counter. The insurer pays the rest directly to the institution. For most working-age adults that share is 30 percent, which is where the familiar "70/30" shorthand comes from.

What the percentage is applied to matters as much as the percentage itself. Japan runs a national fee schedule, so the same consultation, the same X-ray and the same blood panel carry the same official price in a clinic in rural Akita and a clinic in central Osaka. Nobody is quoting you a private rate. Beyond that, many municipalities run their own subsidy for children's medical costs, sometimes reducing the bill to zero up to a certain age — the rules differ city by city, so ask at your ward or city office.

Some things fall outside insurance entirely. Routine health checkups, vaccinations that are not part of a public programme, cosmetic procedures, most adult orthodontics, a normal uncomplicated childbirth, and medical certificates written for your employer are all self-pay, priced by each institution. So is the no-referral charge in the previous section.

When the bill gets big: the high-cost medical expense benefit

Thirty percent of a routine visit is a few thousand yen. Thirty percent of surgery and two weeks in a ward is not. This is the point of the high-cost medical expense benefit: within a single calendar month, once your own share of insured treatment passes a ceiling based on your income, everything above the ceiling comes back to you. The ceilings were revised upward from August 2026, and at the same time a new annual ceiling was introduced, running from August to the following July.

The figures below are for people under 70. From 70 onward the ceilings are lower and outpatient care has its own separate per-person cap — 22,000 yen a month (216,000 yen a year) in the ordinary income band, 11,000 yen a month (96,000 yen a year) for municipal tax exempt households — so check your insurer's table for the over-70 rules rather than this one.

Note that the two ceilings work differently. The monthly ceiling can be applied at the counter so you never front the money. The annual ceiling cannot — once your accumulated share for the August-to-July year passes it, you claim the excess back from your insurer as a refund, so keep every receipt. Households confirmed to be in the roughly 2 million yen or below income band have a 410,000 yen annual ceiling instead, refunded from August 2027 onward.

A worked example makes the arithmetic concrete. Suppose treatment costs 1,000,000 yen in total and you sit in the middle bracket. Your 30 percent share would be 300,000 yen. Your ceiling is 85,800 + (1,000,000 − 286,000) × 1%, which is 92,940 yen. The remaining 207,060 yen is not your problem.

There is also a mechanism for people in long treatment: if you hit the ceiling in three months out of the last twelve, the ceiling drops from the fourth month onward, to the figure in the third column.

The important practical point is that you do not have to pay 300,000 yen and wait months for a refund. Present a My Number Card registered for health insurance use and consent to sharing your limit information, and the counter simply stops at your monthly ceiling. If you do not use one, apply to your insurer in advance for a limit-application certificate and show that instead.

What to bring, and how a visit actually runs

Old-style paper health insurance cards stopped being valid on 1 December 2025, and the grace period for presenting an expired one ended on 31 July 2026. From August 2026 onward you need either a My Number Card registered for health insurance use, or a Qualification Confirmation Document, which your insurer issues free of charge and without an application if you do not hold the former.

The sequence is the same almost everywhere. You hand over your identification at reception. As a first-time patient you fill in a form covering symptoms, when they started, allergies, past illnesses, current medication and, for women, possible pregnancy. Then you wait for your number. The consultation itself is often short — Japanese doctors tend to work quickly and ask closed questions, so volunteer information rather than waiting to be asked. Tests, if ordered, happen in the same building, followed by another wait. You settle up at the cashier before leaving, and if medicine was prescribed you walk out with a slip rather than the drugs themselves.

The Ministry of Health, Labour and Welfare publishes multilingual medical questionnaires and explanation sheets that you can print at home and hand across the counter. Filling one in before you leave the house is the single cheapest thing you can do to make the visit go well.

Finding a doctor who speaks your language

Language capability is uneven, and it is worth mapping before an emergency rather than during one. The Japan National Tourism Organization runs a searchable directory of medical institutions built on a list compiled by the Ministry of Health, Labour and Welfare together with the Japan Tourism Agency. You can filter by area, by department, by the languages a facility handles and by whether it accepts credit cards. The interface itself works in Japanese, English, Chinese and Korean, and individual entries list a wider range including Russian, Spanish, Portuguese and Indonesian.

For paperwork, the ministry's multilingual explanation materials cover consent forms, questionnaires and treatment explanations in English, Chinese, Korean, Portuguese, Spanish, Vietnamese, Indonesian, Nepali, Tagalog, Thai, Arabic, Hindi and Ukrainian, among others. Hospitals are supposed to know these exist; not all of them do, so bringing your own printout works better than asking.

The Japan Visitor Hotline on 050-3816-2787 runs 24 hours a day in English, Chinese and Korean. It is aimed primarily at travellers, but it will point anyone toward a facility that can handle a foreign language, which is useful at two in the morning when you have no idea where to go.

Three more avenues are worth knowing. Larger hospitals in cities with big foreign populations often employ medical interpreters or coordinators under a ministry support programme, so ask when you book. Most prefectures fund an international association or a one-stop consultation desk for foreign residents that can arrange or accompany. And your employer's human resources department may already have a clinic it uses — asking costs nothing.

Emergencies: 119, and the numbers in between

Dial 119 for an ambulance. It is free to call from any phone, including a mobile with no credit, and it connects to the fire department, which handles both fires and ambulances. The operator's first question is which of the two you need. Answer "ambulance," then give the address, then say what happened. If you can, stay on the line and send someone to the street to wave the crew in.

The ambulance ride itself is publicly funded and is not billed to you. Treatment at the hospital afterwards is billed as ordinary insured care, and because you arrived as an emergency patient the hospital is prohibited from charging you the no-referral special charge.

Call 119 without hesitating for chest pain or pressure, difficulty breathing, sudden weakness or numbness on one side, slurred speech, a face that has dropped on one side, bleeding that will not stop, loss of consciousness, a seizure, a serious burn, or major trauma. Hesitation in these situations costs far more than an unnecessary call.

For the enormous grey zone between "this is fine" and "call 119", there is #7119, the emergency consultation line run by prefectures and local fire authorities under a scheme promoted by the Fire and Disaster Management Agency. Doctors, nurses and emergency medical technicians answer, tell you whether to go now or wait until morning, and transfer you straight to 119 if the answer is now. It runs in 41 areas nationwide, some around the clock and some only in the evenings, so check whether your area has it before you need it.

For children there is #8000, which has covered all 47 prefectures since 2010. It routes automatically to your prefecture's paediatric advice line and operates in the evenings, at night and on holidays — exactly when a small child's fever tends to spike.

The pharmacy afterwards, and going to the dentist

Most Japanese clinics do not hand you medicine. They hand you a prescription slip, and you take it to any pharmacy displaying the insurance pharmacy sign, usually one within sight of the clinic door. The slip has a deadline: four days including the day it was issued, with weekends and public holidays counted, under Article 20, item 3(a) of the Regulations on Insured Medical Treatment. The same rule allows a longer period where the doctor recognises special circumstances such as a long trip, and refill prescriptions — usable up to three times — run on a different clock, with each later use falling within seven days either side of the day the previous supply runs out. Let an ordinary slip expire and you need another consultation to get another one.

Your percentage share at the pharmacy is the same as at the clinic. You will be offered a medicine record book on your first visit; take it, and bring it every time, because it is how a pharmacist catches a dangerous interaction between something prescribed by an orthopaedic clinic and something prescribed by a dermatologist.

One cost trap deserves attention. If a generic version of your medicine exists, you specifically ask for the original brand, and there is no medical reason for the original, you pay a special charge on top of your normal share, outside insurance. From 1 October 2024 to 31 May 2026 that charge was one quarter of the price difference plus consumption tax; since 1 June 2026 it has been one half of the difference plus consumption tax. Where several generics exist, the difference is measured against the most expensive generic. The charge does not apply where there is a genuine medical reason — the generic has different approved indications, you had a side effect or a weaker response on the generic, a clinical guideline advises against switching, or the generic's dosage form is one you cannot swallow or cannot have packaged together — nor where the pharmacy simply has no generic in stock.

Dentistry works on the same insurance and the same percentage as everything else, which surprises people arriving from countries where it does not. Check-ups, cleaning tied to treatment, fillings, root canals, extractions and standard dentures are covered. Material upgrades sit in a middle category where insurance pays the standard part and you pay the difference — a metal-based full denture, or a gold or platinum alloy crown on a front tooth. Whitening for appearance and most adult orthodontics are fully self-pay. And note that large dental hospitals apply the no-referral charge too, from 5,000 yen for a first visit.

Frequently Asked Questions

Can I see a doctor in Japan if I am not enrolled in health insurance?

Yes, a clinic or hospital will treat you, but you pay 100 percent of the cost, and for uninsured patients an institution is not bound by the national fee schedule, so the price can be considerably higher than three times the insured share. Enrolment in public medical insurance is compulsory for residents of Japan, and the enrolment procedure is a separate topic from the one covered here. If you are currently uninsured, sorting that out at your city office is more urgent than almost anything else on this page.

Do I have to pay the extra charge if I go straight to a big hospital in an emergency?

No. Hospitals are prohibited from collecting the special charge from emergency patients, and also from recipients of nationally funded medical care programmes and several other protected groups. Hospitals may additionally waive it when you were referred internally from another department, when you were told to get detailed testing after a health check or cancer screening, when you are admitted directly from the outpatient visit, and for patients treated for a work injury, a public-service duty injury, a traffic accident or on a self-pay basis, patients affected by a disaster, and clinical trial participants. If you are charged in a situation you believe is exempt, ask the counter to explain the basis.

I cannot pay the bill today. What do I do?

Say so at the reception desk before the consultation rather than after. If a large bill is coming, ask your insurer about a limit-application certificate first, or use a My Number Card registered for insurance use, so that the counter charges you only up to your monthly ceiling instead of the full 30 percent. Many hospitals also have a consultation desk that can arrange instalments or point you to public assistance. What you must not do is leave without speaking to anyone.

How do I actually get high-cost medical expense money back?

There are two routes. If you paid the full share at the counter, apply to your insurer — your company's health insurance society or association, or your city's National Health Insurance desk — with the receipts; reimbursement typically takes around three months from the month of treatment. The better route is to avoid paying upfront at all, by presenting a My Number Card registered for health insurance use and agreeing to share your limit information, or by obtaining a limit-application certificate from your insurer before you are treated. Note that this counter-level protection applies to the monthly ceiling only: the annual ceiling introduced from August 2026 is always claimed back from your insurer afterwards, so keep your receipts.

My employer wants a medical certificate. Is that covered by insurance?

No. A medical certificate written for an employer, a school or an insurance company is not treatment, so it falls outside public insurance and each clinic sets its own price for it. Ask what the fee is when you request the document, and ask what exactly the employer needs stated on it, because a certificate written for the wrong purpose usually has to be reissued and paid for again.

Summary

The single most useful habit is starting small. A neighbourhood clinic handles the great majority of what will actually send you to a doctor, sees you faster, costs less, and builds the record that makes a referral credible when you do need a specialist.

That referral letter is worth real money. Walking into a designated advanced-treatment hospital, or a regional medical support or referral-focused hospital with 200 or more general beds, without one triggers a special charge of at least 7,000 yen for a first medical visit and at least 5,000 yen for dental. Emergency patients are exempt.

The 70/30 split is only half the protection. Above a monthly ceiling set by your income, the high-cost medical expense benefit returns the excess, and from August 2026 there is an annual ceiling as well, claimed back from your insurer as a refund. Arranging a limit-application certificate, or using a My Number Card registered for insurance use, means you never front the money against the monthly ceiling in the first place. The ceiling figures in this article are the under-70 ones; from 70 the rules differ.

Preparation beats improvisation. Know which clinic you would go to, carry your insurance identification, keep your address written down for a 119 call, check whether #7119 covers your area, and print a multilingual questionnaire before you are too unwell to think clearly.

Medical fees, ceilings and identification rules in Japan change on fixed dates, often at the start of June, August or October. Check the current figures with the institution or your insurer rather than assuming last year's numbers still apply.

This article is general information about how Japan's medical and public insurance systems work, based on published rules as of August 2026. It is not medical advice and must not be used to decide whether to seek treatment — if you are unwell, consult a doctor, and in an emergency call 119. Fee minimums, copayment rates, high-cost medical expense ceilings and insurance identification rules are set by national regulation and revised periodically, so confirm current amounts with the medical institution, your insurer or your municipality before relying on them.
