What Is Health Insurance in Japan

  • All residents in Japan with long-term visas (over 3 months), including expatriates, are legally required to enroll in one of the public health insurance schemes: Employee Health Insurance (Kenko Hoken / SHI) if employed, or National Health Insurance (Kokumin Kenko Hoken / NHI) if self-employed, unemployed, students, or people whose employer does not provide SHI.  
  • The public insurance covers about 70% of medical costs; the patient generally pays the remaining 30% as a co-payment. For people over a certain age (elderly), or in special cases, co-payment rates may be reduced.  

Types of Public Insurance & Cost Differences

Insurance TypeWho It CoversHow Premiums / Contributions Work
Employee Health Insurance (SHI / Kenko Hoken)People working for companies/employers who provide SHI; includes dependents.  Premium is shared: about half paid by employer, half by employee; based on income.  
National Health Insurance (NHI / Kokumin Kenko Hoken)Those not covered by SHI (students, self-employed, retirees, etc.) and foreign residents with long-term visa.  Premium depends on income, household size, local municipal rates. Not employer-subsidized.  

What’s Not Covered & Supplemental Options

  • Certain medical services are not fully covered by public insurance: dental work beyond basic care, elective procedures, many cosmetic treatments, some mental health services, etc.  
  • Many expats opt for private or international health insurance as a supplement—for ensuring continuity while waiting for public insurance, for treatments public insurance doesn’t cover, or for broader network / English support.  

Practical Cost & Payment Details

  • Public insurance co-payment: usually 30% of medical cost; for elderly (age 75+), or certain low-income groups, it could be 10-20%.  
  • Premiums or contributions: For SHI, based on salary; for NHI, based on income + local government rules + household size.  
  • Medical expenses must often be paid upfront or at time of service, with reimbursement or co-payment deducted later; patients need to present a health insurance card.
