For children living in Adachi City from age 0 until the first March 31 after turning 18, the city fully covers the out-of-pocket share when they receive insured care at a medical institution. There is no parent income limit. If you show the medical certificate (Maru-Nyu, Maru-Ko, Maru-Sei) together with the health insurance card at the counter, you pay nothing. If you see a medical institution outside Tokyo or forget to show the certificate, pay first and apply to the city later with the receipt to be reimbursed. From October 1, 2025, meal costs during hospital stays (standard share of hospital meal costs) were also added. Meal costs are not deducted at the counter, so pay first and apply later with the receipt to get a refund.
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.
