National Health Insurance

All individuals, except those who are enrolled in their workplace health insurance or are receiving welfare assistance, must join National Health Insurance.

• For those with a My Number Health Insurance Card, an "Eligibility Information Notice (A4)" is provided. (The insurer information in the My Number Card will be automatically updated the day after the eligibility notification is submitted.)
• For those without a My Number Card or who have not registered their health insurance card, an "Eligibility Confirmation Letter (Card type: Paper)" will be issued.
• When receiving medical treatment, always present your My Number Health Insurance Card or Eligibility Confirmation Letter at the medical institution's counter.
• Additionally, individuals aged 75 and older (or those aged 65 and older who are certified as disabled) will receive medical care through the Late-Stage Elderly Medical Care System.

When receiving treatment for illness or injury, 70% or 80% of the medical expenses will be covered according to the burden category (you will be responsible for the remaining 30% or 20%).
Other benefits include medical expenses, high-cost medical treatment benefits, high-level nursing care combined medical expenses, childbirth lump-sum benefits, and funeral expenses.

In the case of injury in a traffic accident, in principle, the perpetrator pays the treatment cost.
