Influenza vaccination covered at ¥2,000 per shot (¥4,000 for nasal) (FY2026 from September 16)

Koto City covers part of the cost of influenza vaccination for children. In FY2026 (April 2026–March 2027), because the flu season started early, the start date was moved up from October 1, and it runs from September 16, 2026 to January 31, 2027. The inactivated vaccine (injection) is ¥2,000 per shot, and the live nasal vaccine (FluMist) is ¥4,000 per dose; choose one type. The number of doses depends on the date of birth: born February 2, 2025 to July 1, 2026, up to 2 inactivated doses; born October 2, 2013 to February 1, 2025, up to 2 inactivated doses (or 1 nasal dose); born April 2, 2008 to October 1, 2013, 1 dose. Fully covered for households on public assistance. Pre-vaccination questionnaires were sent to eligible people all at once on September 11. Only individual vaccinations at participating medical institutions in the city contracted with Koto City are covered; vaccinations without the questionnaire or before September 16 are fully paid by you.
