For children living in Chiyoda City from age 0 to the first March 31 after turning 18, the city fully subsidizes the out-of-pocket cost (usually 30% or 20%) when they receive insured treatment at a medical institution. There is no income limit.

If you show the "child medical certificate" together with your health insurance card at the medical institution's counter, there is no out-of-pocket cost (= nothing to pay at the counter). If you receive care outside Tokyo or forget to show the certificate, pay the out-of-pocket cost first, then apply to the city later with the receipt to get a refund.

Insured treatment (consultations, medication, procedures, tests, hospital stays, surgery, etc.) is covered. Non-insured treatment, room charge differences, health checkups, vaccinations and similar are not covered. Meal costs during hospital stays have been covered by a cash subsidy for treatment on or after April 1, 2025.

Nationality and residence status

The official page (checked in October 2026) sets no condition on nationality or residence status that we found. Eligibility follows the official conditions, not the language of this page; many programs require resident registration in the municipality.
