Frequently asked questions
Is health insurance optional in Japan?
No. Public insurance is mandatory for residents staying three months or more, through either employees' health insurance or National Health Insurance. If your stay crosses that threshold, enrolment is an obligation.
How much do patients pay in Japan?
Generally 30% of medical costs, with lower rates for children and older people. Coverage is broad, but it is a co-payment system rather than free at the point of use, so budget for that share.
Where do I enrol in National Health Insurance?
At your local municipal office, typically at the same time as registering your address. Doing both in one visit saves a second trip and gets your insurance card moving sooner.
