Planning a trip to Japan or considering a long-term move, and wondering whether you can access Japan health insurance for foreigners?
Many visitors worry about unexpected medical costs or getting sick abroad without proper coverage.
The short answer is: tourists cannot use Japan’s public health insurance system, but long-term residents are required to enroll and receive comprehensive coverage.
Japan operates a universal healthcare program that covers approximately 70% of medical expenses.

By the end of this guide, you’ll understand exactly which insurance options apply to your situation.
Can Tourists Use Japan Health Insurance for Foreigners?
No, tourists cannot use Japan’s public health insurance system during short-term visits.
Eligibility for Japan health insurance for foreigners is determined primarily by your residence status (在留資格).
Japan’s universal healthcare coverage applies only to foreign nationals who are registered as residents (住民登録) at a local municipal office and hold a qualifying residence status under the National Health Insurance Law.
Travelers visiting Japan for medical purposes under a Medical Stay Visa (医療滞在ビザ) are generally not eligible for public health insurance. It is strongly recommended that you arrange private insurance coverage prior to arrival.

National Health Insurance (NHI)
National Health Insurance serves as the safety net coverage for foreign residents who don’t qualify for employer-sponsored insurance.
NHI applies to foreign nationals holding a residence status with a designated period of stay exceeding 3 months, regardless of the actual length of stay at the time of enrollment.
NHI Coverage and Eligibility:
| Category | Details |
|---|---|
| Eligibility | ・Self-employed / Freelancers ・International students ・Job-seekers / Unemployed ・Part-timers (w/o employer insurance) |
| Premiums | ・Based on previous year’s income ・Varies by household & municipality ・Range from several thousand to tens of thousands of yen |
| Co-payment | • 30% of medical expenses (standard rate) • High-cost Medical Expense Benefit available for expensive treatments |
The premium structure under NHI reflects your financial capacity, with reduction or exemption systems available for low-income households.
Since each municipality calculates premiums using its own formula, costs vary significantly between Tokyo’s central wards and smaller regional cities for the same income level.
Social Health Insurance (SHI)
Social Health Insurance, commonly known as Employees’ Health Insurance, provides coverage for foreign workers employed by Japanese companies under qualifying employment contracts.
This employer-based system requires mandatory enrollment for both Japanese and foreign nationals.
SHI Coverage and Eligibility:
| Category | Details |
|---|---|
| Eligibility | • Full-time employees (seishain 正社員) • Contract workers, part-time staff meeting minimum hours/duration • Foreign employees working for Japanese companies |
| Premiums | • Based on monthly salary amount • Employer pays 50%, employee pays 50% • Automatically deducted from paycheck |
| Co-payment | • 30% of medical expenses (same as NHI) • High-cost Medical Expense Benefit applies equally |
Under SHI, your employer contributes half of the total premium, meaning you don’t bear the full insurance cost alone.
This cost-sharing structure ensures predictable medical expenses and provides access to Japan’s broader public health benefits framework.
How Much Does Japan’s Health Insurance Cost for Foreigners?
The cost of Japanese health insurance for foreigners varies significantly based on your income level and employment status.
Monthly Premium Comparison by Income Level:
| Income Level | NHI | SHI (Health Insurance ONLY) |
|---|---|---|
| ¥200,000/month | Approx. ¥15,500 | ¥9,910 |
| ¥300,000/month | Approx. ¥22,800 | ¥14,865 |
| ¥400,000/month | ¥40,000–55,000 | ¥20,316 |
*Japan Health Insurance Association “Medical Insurance System in Japan“
The above figures are illustrative estimates based on Tokyo 23 wards (FY2025).
NHI premiums vary by municipality, household composition, and number of dependents.
SHI figures are based on Kyokai Kenpo (協会けんぽ) rates for Tokyo and reflect the employee’s share only.
All calculations assume a single-person household under age 40, excluding nursing care insurance premiums (介護保険料).
Actual costs may differ significantly based on individual circumstances.
For someone earning ¥300,000 monthly, the difference amounts to approximately ¥7,900 per month in out-of-pocket insurance costs.
What Tourists Should Do Instead for Health Insurance in Japan
Since tourists cannot access Japan’s public health insurance system, purchasing travel insurance before or upon arrival is essential to protect against high medical costs during your visit.
The Japan National Tourism Organization (JNTO) strongly recommends that all international visitors obtain comprehensive travel insurance coverage.
