Health insurance system in Japan
Mandatory coverage for all residents in Japan. It includes both Japanese citizens and Non-Japanese citizens. Enrollees have no choice of health insurance programs.
Plans are designated according to the enrollee's employment status, age, and residence.
Japanese patients are free to receive care from the medical facility of their choosing. There is no primary doctors or gate keepers. For example, a man who works at a firm in Tokyo can visit a specialist at the hospital near his office without a referral, then in the same week be seen by a physician at a clinic near his home.
Same co-payments across all plans
Medical service fee is determined by the Minister of Health, Labour and Welfare.
It is revised every year. Co-payment is basically the same for all services(Burden ratio varies according to age of patients.)
Types of medical facilities
In Japan, medical institutions are divided into the following types.
