National Health Insurance announcement

Every July, Takasaki sends out several announcements regarding National Health Insurance (NHI). Be sure to check the ones relevant to you when they arrive in the mail.

NHI payment slips

Insurance rates for both regular members and members of the Latter-stage Elderly Healthcare system have been adjusted for Reiwa 8 (which runs from July 2026 to June 2027). A notice will be sent that contains more information along with the payment slips. Be sure to pay each one on time. For more information about payment deadlines, see here.

Proof of insurance coverage

Members of NHI can verify their health insurance information with different types of certificates. Every type of certificate will get renewed and sent to members in the mail unless otherwise noted. Please use the new one from August. 

Health Insurance Eligibility Certificate

The Health Insurance Eligibility Certificate (shikaku kakunin-sho in Japanese) is given to any member who either does not have a My Number card, or who has not set theirs up to function as a health insurance card. The postal envelope will be addressed to the head of household. 

Notice of Eligibility for Health Insurance

The Notice of Eligibility for Health Insurance (shikaku joho no oshirase in Japanese) is given to any member who has a My Number card and set it to function as a health insurance card. It can be used as a backup in situations where the My Number card itself cannot be used. It will be sent to all members under the age of 70 who have not already received it previously.
