When children registered as residents of Musashino City, from age 0 until the end of the fiscal year in which they turn 18, receive insurance-covered care at hospitals and similar, the city subsidizes the co-payment. Preschool children receive the Maru-Nyu medical certificate, elementary and junior high school students Maru-Ko, and those from junior high school graduation until the end of the fiscal year of age 18 Maru-Sei; at medical institutions in Tokyo, if you show it with your My Number health insurance card, there is no payment at the counter for insurance-covered care. Costs not covered by insurance, such as vaccinations, checkups, meal costs during a hospital stay and private room charges, are excluded. If you apply within 2 months of birth or moving in, the subsidy applies retroactively from that date. If you see a doctor outside Tokyo, apply for a refund by mail.

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.

Who is eligible

People registered as residents of Musashino City raising a child enrolled in health insurance, until the first March 31 on or after the 18th birthday

Notes

There is no payment at the counter for insurance-covered care. Children on public assistance, in institutions or in foster care are not eligible.
