Everyone in Japan is expected to belong to some form of health insurance. If you are not joining an employer plan, you will usually need National Health Insurance.

What it covers

In general, you pay 30% of eligible medical costs at the clinic or hospital, and the insurance covers the rest.

How to enroll

People often complete enrollment at the same time as residence registration at city hall. In many cases, you can do both in one visit.

Bring:

  • Residence card
  • Passport
  • My Number, if requested

Where you can use it

National Health Insurance is accepted at most hospitals, clinics, and dental offices in Japan.

Typical cost

Premiums are based on income. In your first year in Japan, if you had no prior Japanese income, the cost is often relatively low.

Not everything is covered

Some dental work, vision correction, and elective treatments may not be fully covered.
