2026 Mizumoto Park Fountain Plaza: Full-Day Course

Mizumoto Park in Katsushika City has a free water play area, the Mizumoto Park Fountain Plaza (Water Play Area), that starts up only in summer. The 2026 season runs Wed 7/1 to Wed 9/30 from 9:00 to 16:00, with the fountain pausing between 12:00 and 13:00. Inspection and cleaning closure days are 8/12, 8/18, 9/4 and 9/15. The venue is Mizumoto Park in Katsushika City, a vast park with the only waterside landscape of its kind in Tokyo, where rows of poplars and a forest of dawn redwoods follow a pond called Koaidame (小合溜). Admission is free, and there are restrooms and a shop in the park. In the morning, visit Shibamata Taishakuten (柴又帝釈天) and finish lunch while buying kusa dango in the temple-gate town along the approach. In the afternoon, see the colorful goldfish at the Goldfish Exhibition Area in Mizumoto Park, then play in the water at the Fountain Plaza until the 16:00 close. Reachable by the Keisei Kanamachi Line (京成金町線) and bus, it is a day that links the waterside and the temple-gate town in true Katsushika style.
