Does Japan's health insurance cover foreigners?

Yes. Foreign residents registered in Japan are required to enroll in either National Health Insurance (for those not covered by employer insurance) or employee health insurance through their workplace. Both systems cover most medical services at 70% of the standard fee, leaving 30% as the patient's copayment.

What do I do if I need a doctor but don't have my insurance card yet?

You can still receive care and pay the full fee upfront. Once you receive your insurance card, you can apply for retroactive reimbursement at your municipal office. Keep all receipts.

Is emergency care covered by insurance?

Yes. Emergency care is covered under the standard insurance scheme. The 30% copayment applies even in emergency situations, though the high-cost medical expense benefit caps out-of-pocket spending for a single month.

Do I need a referral to see a specialist?

Not technically required, but large hospitals charge an additional surcharge (tokubetsu ryōkin) if you arrive without a referral letter. Starting at a clinic and getting a referral is usually faster and cheaper.

System Basics

How Japan's Healthcare System Works

An overview of Japan's universal healthcare system — how it is organized, who pays for what, and what foreign residents need to know to navigate it effectively.

Who this is for

Anyone new to Japan who needs to understand the overall structure of the healthcare system before using it.

The structure of Japan’s health system

Japan operates a mandatory universal health insurance system, in place since 1961. Every resident — including foreign nationals with a valid residence status registered at their municipal office — must enroll in one of the insurance schemes. The two principal schemes are National Health Insurance (国民健康保険, Kokumin Kenkō Hoken, commonly called NHI or Kokuho) and employee health insurance (社会保険, shakai hoken). Which scheme you join depends on your employment situation.

The Ministry of Health, Labour and Welfare (MHLW) sets the rules and fee schedules for all covered services. Hospitals and clinics across Japan must charge the nationally standardized fee for any covered service — there is no negotiation, and private clinics do not charge more than public hospitals for covered treatments. This creates a level of price transparency unusual in many other countries.

Who can enroll

Foreign residents in Japan are eligible for health insurance once they register at the local municipal office (市役所, shiyakusho or 区役所, kuyakusho). Registration requirements depend on visa status, but most residency categories with a valid period of stay longer than three months create an obligation to enroll. This includes long-term residents, students, working visa holders not covered by their employer, and family members of enrolled individuals.

If your employer registers you in the employee insurance scheme (shakai hoken), you do not also need to enroll in NHI. If you are self-employed, between jobs, a student, or your employer does not offer shakai hoken, you enroll in NHI through your local municipal office. When changing jobs, you have a brief window to either maintain your former employer’s insurance through voluntary continued membership or switch to NHI.

How services and billing work

When you visit a clinic or hospital, you present your insurance card (保険証, hokenshō) at the reception desk. The medical institution bills the insurance fund directly for 70% of the standard fee and collects the remaining 30% from you at checkout. This 30% copayment applies to most services, though there are different rates for children and those aged 70 or older.

The standard fee schedule covers a wide range of services: outpatient consultations, diagnostic tests including blood work and imaging, inpatient care, surgical procedures, prescriptions dispensed at a hospital pharmacy, and many dental treatments. Certain items are not covered, including cosmetic procedures, routine dental check-ups in some settings, elective care for conditions not meeting diagnostic criteria, and treatments using explicitly uncovered pharmaceuticals.

Prescriptions are handled separately. After a clinic visit you receive a prescription slip (処方箋, shohōsen), which you take to a pharmacy — typically a freestanding pharmacy near the clinic rather than an in-hospital dispensary. The pharmacy bills insurance for its portion and collects your 30% copayment at the counter.

Public health centers and their role

Public health centers (保健所, hokenjo) are prefecture-operated facilities distinct from hospitals and clinics. They provide population-level public health services: tuberculosis screening and treatment supervision, vaccination programs, communicable disease surveillance, maternal and child health support, and mental health consultations. Many of these services are free or heavily subsidized and are available to foreign residents regardless of insurance enrollment status.

Public health centers are not primary care providers — they do not treat individual illness in the way a clinic does — but they are important access points for preventive care and public health programs. Your nearest hokenjo contact can be found through your prefectural government website or by asking at your municipal office.

Safety nets and cost ceilings

Out-of-pocket costs are capped by the high-cost medical expense benefit (高額療養費, kōgaku ryōyōhi). If your monthly medical bills exceed a threshold that is calculated based on your income, the insurance fund reimburses the excess. This prevents catastrophic healthcare spending for serious illness or hospitalization. The system operates on a monthly cycle, and applications are typically submitted after the fact through your municipal office or health insurance fund.
