The National Health Insurance program (Kokumin Kenko Hoken) is one form of public health insurance, and the program is operated at the municipal level.

If you show your health insurance certificate at the reception desk before receiving medical treatment, you will then only need to bear 30% of the medical expenses for the services received. If you file an application in the following cases, you may receive a reimbursement upon review of your application, although you must initially pay the full amount. However, applications for reimbursements are not approved in all cases.
(1) If you paid the medical institution for the entire cost of medical treatment because you were unable to show your health insurance certificate in an emergency or other unexpected situation.
(2) If you have body support equipment made, such as a surgical corset under a doctor’s recommendation, and paid the entire cost.
(3) If you received massage, acupuncture or moxibustion treatments under a doctor’s recommendation.
(4) If you have transportation costs that are recognized as necessary by a doctor.
(5) If you pay for medical treatment for illnesses or injuries incurred while traveling overseas. (A stipulated form to be completed by the doctor oversea is required.) However, this excludes traveling overseas for the purpose of receiving medical treatment.
Applications are handled at the National Health Insurance Section (first floor of Mitaka Municipal Office) or at any branch office.
If the personally-borne expenses (varies according to income) for medical treatment at one medical institution exceed a designated amount for one person within the same month (from the 1st to the last day of the month), the excess may be reimbursed as a high medical expense benefit upon application. As a rule, those who are eligible for this benefit are sent an application in the mail within about two months after receiving medical treatment, so please complete the application procedures at the National Health Insurance and Pension Section on the first floor of Mitaka Municipal Office or at any branch office.

A benefit of ¥50,000 is offered to the chief mourner when an insured member dies.
