National Health Insurance (NHI) is a mutual assistance program in which members pool their money (insurance premiums) and use the money for medical treatment when necessary, since an illness or injury can happen at any time.

Everyone except those enrolled in the health insurance plan (health insurance union or mutual-aid union) of their place of employment and their dependents, and those who receive public financial assistance for everyday living, must be enrolled in NHI. This includes foreign residents who have completed foreign resident registration and are authorized to stay in Japan for three months or longer. (However, if your visa status is “Diplomat” or “Medical/Special Activities,” you cannot enroll in the program.)
Insurance premiums are calculated for the fiscal year (April through March of the following year) according to the total income the member earned during the previous year. Premiums are calculated by month if an NHI member joins or withdraws during the fiscal year.

As a rule, the payment of premiums for the fiscal year is done in nine installments from July through March of the following year.

When Insurance Cannot Be Used

  1. Matters that are not considered illnesses or injuries
    • Regular pregnancy/childbirth
    • For an abortion due to financial reasons
    • For health checkups, immunizations, complete health checkups or orthodontic treatment
    • For cosmetic surgery
  2. For illnesses or injuries at work that labor casualty insurance can cover
  3. For illnesses or injuries resulting from fighting or drunkenness
  4. For illnesses or injuries induced deliberately or during criminal activities

Note: If health insurance is used for treatment of an injury caused by a third party, such as a traffic accident, then a notification must be filed.

National Health Insurance Premiums

National Health Insurance premiums are calculated for each household member and household, and the notification (invoice) is mailed to the head of the household. Accordingly, the head of the household is obliged to pay the premiums. Even if the head of the household is not enrolled in NHI, the notification (invoice) will be sent to him/her if a household member is an insured member. This is referred to as a “quasi-household.”

How the National Health Insurance Premiums Work

NHI premiums are determined from the total of the medical insurance portion, latter-term elderly support portion and nursing care portion.

Enrolling or Withdrawing during the Fiscal Year

NHI premiums are calculated for the fiscal year from April through March of the following year. Accordingly, if there are any changes during the fiscal year, such as enrollment or loss of eligibility, the premiums are calculated by the number of months of enrollment.

In the Case of Additional Premiums or Partial Loss

If you have a new household member to enroll in NHI or if a family member loses NHI eligibility due to enrollment in the insurance plan at their place of employment, the premium amount will be recalculated based on the number of months of enrollment, and the annual premiums will be adjusted.
