National Health Insurance

Japan has a National Health Insurance system (kokumin-kenko-hoken) to reduce the burden of medical expenses. In general, all foreign nationals who are issued a residence card, including
international students and researchers, are required to obtain National Health Insurance.
After you joined the insurance, you only have to pay 30% of medical expenses at the counter of the hospital. You will be charged a large amount of money without National Health Insurance if you have to go to a medical institution for treatment due to an unexpected illness or accident even you have a confident in your health.
Also, you will be asked to show your National Health Insurance card (hokensho) when you go through immigration procedures such as the renewal of your period of stay.
Be sure to pay your National Health Insurance premiums properly so that you do not lose your assistance due to delinquency.

Where to register

You can apply for this service when you register your new address in Japan at the city hall or the ward office. Payment is not required at application.

Requirements for registration

1, Application form （国民健康保険用所得申告書）
　　This is income declaration form for National Health Insurance. The form is available at the city hall or the ward office. It is also ready at ISD.
2, Residence card・Passport

Insurance fees

Insurance premiums are determined based on your annual income for the previous year, and the amount varies in each municipality. (Scholarships are not considered as income.) After completing the enrollment procedures, you will receive a payment slip, which you can pay in a lump sum or in installments.
In some cases, you may be able to receive a reduction in the amount of premiums you pay depending on your income. To receive this reduction for Chiba city residents, you need to submit an income declaration form for National Health Insurance to the ward office between January and March every year. The form is also available at ISD office. If you are a resident of Matsudo City, please declare your "City and Prefectural Tax（「市県民税」）" at Matsudo City Hall.

How it does work

When you join this system, the insurance holder’s card (hokensho) will be issued on the spot on registration. When you go to a hospital for a medical examination, be sure to bring your insurance card to the counter, then the medical expenses will be automatically calculated using your insurance.
If you do not present your insurance card, you will be required to pay the full amount of the medical bill. Even in such a case, you can get a refund for the difference by presenting your insurance card later, so please follow the instructions at the hospital counter. However, please note that the refund may not be given unless it is within the same month as the date of the medical examination.

Applying for premium reduction

Premiums are determined by the previous year's income. If you have a low income, you can get a reduced (lower) premium by declaring your income.
Residents of Chiba City can reduce their insurance premiums for the following year by submitting the form to the Chiba City (Ward) Office between January and March each year.

When returning to your country

When you return to your home country after completing your study in Japan, please go to the municipal office to complete the procedures for leaving the insurance. If you have overpaid your insurance premiums, you will receive a refund. The procedure can be available about one month prior to your return date. For this procedure, you will need to provide proof of your return (e.g., a copy of your airline ticket or e-ticket). If you do not complete the procedure, you will be billed for the premiums even after you return to your home country, so be sure to complete the procedure together with the notification of moving out.
