Public Medical Insurance System
All the residents in Japan including foreign nationals who will live in Japan for more than three months have an obligation to enroll in the public medical insurance system. In Japan, there are two types of public medical insurance: Employee‘s Health Insurance by employers and National Health Insurance by municipalities. When the members of the public medical insurance system receive medical treatment etc. at any insurance hospital/clinic, they must present their health insurance cards at the reception and in principle pay 30% of the medical expenses. If certain conditions are satisfied, the member may receive the predetermined amount of insurance money in the event of serious illness or injury, delivery, or death.

Receiving Medical Treatment
The first-come-first-served system is employed at many clinics and hospitals in Japan, however, some clinics and hospitals such as dentists require appointments in advance.
Clinics and hospitals are generally closed on Sundays, national holidays and the year-end and new-year holiday period. However, there are local emergency medical centers, and after-hours clinics that provide medical treatment for victims of traffic accidents and sudden illnesses.
