2026 Akatsuka Park Splash Pond: Full-Day Enjoyment Course

Akatsuka Park (赤塚公園) in Itabashi City has a free water-play spot open only in summer, the Akatsuka Park Splash Pond (赤塚公園 じゃぶじゃぶ池). In 2026, the season runs from Wednesday, July 1 to Wednesday, September 30, with hours of 10:00-15:30. It's closed for cleaning and inspection on August 4 (Tue), August 13 (Thu), and September 3 (Thu), and there may also be closures depending on weather or temperature. The venue is Akatsuka Park in Itabashi City. This park stretches long and narrow along the escarpment of the Musashino Plateau, and is one of Itabashi City's foremost spots of remaining nature, home to wooded slopes and a natural habitat of nirinso (Anemone flaccida) flowers. Admission is free, and there are restrooms in the park. You cannot enter the water wearing shoes, so prepare water-play sandals or be ready to go in barefoot. In the morning, visit Joren-ji Temple (乗蓮寺), known for the Tokyo Great Buddha, and trace the area's history at the Itabashi City Local Museum, built on the site of Akatsuka Castle Ruins. For lunch, spread out a bento in the shade of the park, and in the afternoon, play in the Splash Pond until it closes at 15:30. Accessible via the Toei Mita Line, this is a day that connects Akatsuka's greenery and history.
