- Meal costs during a hospital stay and items not covered by insurance are excluded
Under the Tokyo program, elementary and junior high school students (Maru-Ko) and high school-age children (Maru-Sei) still pay up to ¥200 per outpatient visit. Mizuho Town had already made medical care free up to junior high school, and from October 1, 2024 it also removed the ¥200 per outpatient visit for high school-age children. As a result, from age 0 to 18 there is no out-of-pocket share under health insurance. There is no income limit. Meal costs during a hospital stay and items not covered by health insurance are excluded.
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 living in the town raising a child up to the first March 31 on or after the day the child turns 18
Notes
Eligibility is reviewed every year, and a new medical certificate valid from October 1 is sent. Care at medical institutions outside Tokyo and similar can be claimed by reimbursement.
