The city subsidizes the co-payment for insurance-covered care for children registered as residents of Komae City and enrolled in health insurance. Before elementary school, use the Maru-Nyu medical certificate; elementary and junior high school students use Maru-Ko; high school-age children (from April 1 at age 15 to March 31 at age 18) use Maru-Sei. From October 2025, the partial co-payment of ¥200 per outpatient visit for elementary, junior high and high school-age children was removed, and the income limit for high school-age children was also removed. There is now no income limit from age 0 to the end of the fiscal year of age 18. Apply at the Children and Youth Policy Division on the 3rd floor of City Hall or by mail. Apply within 3 months of the date of birth.

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 Komae City raising a child enrolled in National Health Insurance or social insurance, until the end of the fiscal year in which the child turns 18

Notes

From October 2025, the partial co-payment (¥200) for outpatient visits under Maru-Ko and Maru-Sei was abolished, and the income limit for Maru-Sei was also abolished.
