National Health Insurance(NHI)

※Please refer the attached “National Health Insurance Guidebook” for details about the system.

Japan has a healthcare system that alleviates the medical expense paid out of pocket when you fall ill or suffer an injury while pursuing daily activities. The NHI is one of the healthcare system. Foreigners registered as residents in Japan must also enroll in the NHI if they will not enroll in any other public health insurance.

The person enrolled in the NHI must contribute a premium based on his or her income. In return, the enrollee becomes entitled to receive treatment under the insurance when sick or injured.

A person who has registered as a resident of Toshima City and for whom none of the 1-5 below applies must enroll. You cannot enroll or terminate membership according to your free will.

※You must enroll in NHI even if you are enrolled in foreign student life insurance, life insurance with health benefits or travel casualty insurance.

and any dependents of such person
  2. Those receiving welfare benefit
  3. Those whose period of stay in Japan is three months or less
    ※ Even if your visa is for three months or less, you are eligible to join NHI if you can prove that you will be residing in Japan for more than three months, such as with a school enrollment certificate. Please consult us for your eligibility.

After renewing the visa period of stay

Once your visa period of stay expires, your eligibility for NHI membership also expires, so you can no longer receive treatment using the NHI certificate. Even if you renew your visa, if the expiry date for your NHI certificate has remained the same, you cannot receive treatment using the NHI. If you renew your visa at the Immigration Services Agency of Japan, please also complete procedures to renew your NHI certificate at the NHI Section. Even if you are in the process of renewing your visa or status or in the departure preparation period, please complete renew your NHI certificate at the NHI section. At that time, please bring your NHI certificate and residence card. However, if your visa status changes to “activities with medical treatment” or “activities taking care of the person who receives medical treatment in everyday life” within the “designated activities” category, you do not qualify for NHI membership. For those with a “designated activities” visa status, additional relevant documentation is required.

If you lose NHI eligibility

If you lose eligibility, you will be responsible for paying all medical fees you incur at hospitals. If you obtain a short-term visa status, you may be able to get a new NHI certificate or receive reimbursement of the personally borne expenses, but you will also be responsible for paying insurance premiums during that period.

Please file a tax report

NHI fees are calculated based on the total income amount. Resident taxes are the basis by which to calculate the amount of insurance premium or to judge the reduction amount for the flat rate so we ask that even those without an income or with little income file resident taxes.

The tax report should be filed at the tax section of the municipality office of the address where you were registered on January 1 of the filing year.

If you came to Japan on or before January 1, 2020

Please file a resident’s tax report at the municipal office of the address where you were registered as of January 1, 2020.

If you came to Japan on or after January 2, 2020

 If you have just come to Japan, please file a “NHI Premium-related Report” at the NHI Section.

Premiums

Those enrolled in Toshima City’s NHI must pay insurance premiums from the month they become a member (the month they move into Toshima City or switch to NHI from a different health insurance plan). This is calculated per household unit based on last year’s income amount and the number of people in the household. Head of the household pays the total amount for the household.

Please be sure to pay your premiums

Everyone in Japan is obliged to enroll in public medical insurance and promptly pay their insurance premiums by the due date. Even if you have no plans to see a doctor, you must pay the insurance. There are no student discounts.

Administrative action will be taken if premiums are not paid

If the premium is not paid by the due date, a reminder notice will be sent. Additionally, you may be reminded in writing, by phone or through visits to your residence.

If you do not pay within a certain period after receiving the reminder notice, documents will be sent to your employer, bank or other organization to inquire about your salary, property and the like, and administrative action (seizure) will be taken.

If you know that your payments will be late, or if you are facing difficulties in making payments, be sure to indicate a payment plan.

At this time, we will confirm your earnings and living situation. If you do not comply with these inquiries, or if you make false claims, you may be subject to punishment.

Please be aware that if you do not pay your National Health Insurance premiums, you may not be able to change your status of residence or renew your visa at the Immigration Services Agency.

In some cases, a National Health Insurance card with a shortened period of validity or a qualifying certificate for the person insured—which obliges the insured member to be temporarily fully responsible for all expenses incurred at medical facilities—may be issued.

Disbursement of Insurance benefits

When you are ill or injured, you can receive the necessary treatment at a medical institution by presenting your NHI certificate. When you receive treatment, pay 30% of the medical expenses (20% for those up to six years old until the first March 31 after their sixth birthday, and 20% or 30%* for those 70 years old and older) at the medical institutions. The remaining expenses will be paid by Toshima City.

If you receive treatment without presenting your NHI certificate you will have to pay for the full amount of the treatment.

If you use a NHI certificate even though you have moved out of the city or lost your eligibility due to visa expiration, etc., you will be charged by Toshima City for all expenses the city covered on your behalf. Furthermore, using someone else’s NHI certificate will be reported to the police.

※Children until 12th grade (up until the first March 31 after their eighteenth birthday) do not have any amount of self-pay due to medical expense support.

Treatments not covered by NHI (All amount self-pay)

General medical checkup, vaccinations, cosmetic surgery, etc., will not be covered by NHI. For details, please refer to the “National Health Insurance Guidebook.”
