- Until the first March 31 after turning 18
This program covers the out-of-pocket share when children living in Sumida City, from age 0 until the first March 31 after turning 18, receive insured care at a medical institution. If you show the "child medical certificate (Maru-Nyu, Maru-Ko, Maru-Sei)" and your My Number health insurance card (or eligibility certificate, etc.) at the counter, you can see a doctor without paying the out-of-pocket share of insured care. If you see a doctor outside Tokyo, etc., you pay first and can be reimbursed by applying to the city (with receipts within 5 years from the day after payment). Health checkups, vaccinations, hospital meal costs, etc. are not covered.
