Healthcare Costs in Japan: What Expats Need to Know

Living in Japan as an expat offers access to one of the world’s most efficient and high-quality healthcare systems. Japan provides universal health coverage to all residents, including foreigners staying longer than three months. While the government covers about 70% of medical costs, patients typically pay around 30% out-of-pocket. Without proper health insurance, these costs can still add up, especially for specialist treatments or hospital stays.

Alea is a licensed health insurance broker that compares more than 50 insurers for expats in Asia. The figures below come from Japan's Ministry of Health, Labour and Welfare (MHLW), Japan Health Insurance Association (Kyokai Kenpo) and city governments, checked in October 2026.

1. Understanding the Healthcare System in Japan: Universal Coverage with Public and Private Providers

Japan’s healthcare system is based on universal health insurance, ensuring all residents-including expats-have access to medical care. Coverage is provided mainly through two public insurance schemes:

• Employee health insurance (shakai hoken): for company employees. With Japan Health Insurance Association (Kyokai Kenpo), the national average premium is 9.90% of salary from March 2026, shared with your employer; the rate varies by prefecture (10.13% in Osaka). Employees aged 40 to 64 also pay 1.62% for long-term care insurance.

• National Health Insurance (kokumin kenko hoken): for the self-employed, students, freelancers and others without employee insurance. Your city sets the premium from your income and household. For fiscal 2026 the maximum is 1,130,000 yen a year per household (670,000 medical, 260,000 elderly support, 170,000 long-term care and 30,000 for the new child-rearing support levy).

Foreign residents whose permitted stay is longer than 3 months must enroll; it is not optional. Both schemes pay most of the bill and you pay the rest at the counter:

• Children before primary school age: 20%

• From primary school age to 69: 30%

• Ages 70 to 74: 20% (30% for high earners)

• Age 75 and over: 10% (20% or 30% for higher incomes)

Public Hospitals and Clinics:

• Provide most healthcare services, including general consultations, specialist care, dental, mental health, and prescription drugs.

• Fees are strictly regulated by the government to keep costs affordable.

• You can choose any clinic, but large hospitals (special function hospitals, which include most university hospitals, and regional support hospitals with 200 or more general beds) charge an extra 7,000 yen for a first visit without a referral letter, and 3,000 yen for a return visit after they have referred you back to a clinic.

Private Hospitals and Clinics:

• Operate alongside public providers and often offer more comfort, private rooms, and English-speaking staff.

• Costs can be higher, and upfront payments may be required.

2. How Much Does Healthcare Cost for Expats in Japan?

Consultations & Routine Medical Care

Japan does not set prices hospital by hospital. Every insured clinic and hospital, public or private, bills from the same national fee schedule set by the MHLW, and you pay your share (usually 30%). The table shows the average total cost per day of care in fiscal 2025 (April 2025 to March 2026) and what that means at 30%.

Over a full year, Japan spent an average of 400,000 yen per insured person on medical care in fiscal 2025: 212,000 yen for people on employee insurance and 415,000 yen for National Health Insurance members, who are older on average. Without Japanese public insurance, you pay the full bill yourself.

The monthly cap on your medical bills (from August 2026)

The high-cost medical expense benefit (kogaku ryoyohi) limits what you pay each month, whatever the size of the bill. From 1 August 2026 the caps went up and a new yearly cap was added. For people under 70:

Example: a 1,000,000 yen hospital bill for someone in the 3.7 to 7.7 million yen bracket. The cap is 85,800 yen plus 1% of (1,000,000 minus 286,000), which comes to 92,940 yen. The MHLW rounds this to about 93,000 yen. Show your My Number health insurance card (or a limit certificate) at the hospital and you pay only the capped amount at the counter.

Most hospitals and clinics require patients to pay their portion at the time of service. Having supplemental private or international health insurance can help cover these out-of-pocket costs.

3.Vaccination & Preventative Healthcare in Japan

Routine vaccinations are widely available in Japan, with prices varying by clinic.

Average vaccination costs in Japan:

Public hospital: 3,000 - 8,000 JPY per dose (21-56 EUR)

International clinic: 6,000-24,000 JPY per dose (42-168 EUR)

💡 Tip: Vaccinations are generally not covered by Japan’s national health insurance, so you will pay out-of-pocket. Make sure the vaccines administered meet international standards, especially if you plan to travel or return home.

Giving birth in Japan

A normal delivery is not paid by health insurance in Japan. Instead, your insurer pays a childbirth lump-sum allowance of 500,000 yen per baby, usually straight to the hospital, and you pay any difference. See our full guide to giving birth in Japan.

What changed in 2026

• Higher monthly caps and a new yearly cap (1 August 2026). For the 3.7 to 7.7 million yen income bracket, the monthly cap rose from 80,100 yen plus 1% to 85,800 yen plus 1%, and a yearly cap of 530,000 yen now applies. The MHLW plans finer income brackets from August 2027.

• Lower employee premium (March 2026). The Kyokai Kenpo national average rate fell from 10.00% to 9.90%.

• New child-rearing support levy (April 2026). National Health Insurance premiums now include a child-rearing support part, capped at 30,000 yen per household in fiscal 2026.

• Referral surcharge unchanged. The 2026 fee revision kept the extra charge at large hospitals at 7,000 yen for a first visit and 3,000 yen for a return visit without a referral.

4. Do Expats in Japan Need Health Insurance?

While Japan’s universal health insurance provides excellent coverage, expats should consider additional private or international health insurance for several reasons:

• To cover the 30% co-payment and reduce out-of-pocket expenses.

• To access private hospitals, private rooms, and English-speaking specialists.

• To cover treatments or services not fully included under public insurance, such as some advanced therapies or elective procedures.

• To have global coverage if you travel frequently or plan to return home.

Japan's public insurance and monthly cap protect residents from very large bills, so private cover is mainly for the 30% share, private rooms, English-speaking care and cover outside Japan.
