2026 Oizumi Chuo Park Splash Pond: Full-Day Enjoyment Course

Oizumi Chuo Park (大泉中央公園) in Nerima City has a free water-play spot open only in summer, the Oizumi Chuo Park Splash Pond (大泉中央公園 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 on August 6 and September 2, and there may also be closures depending on weather or temperature. The venue is Oizumi Chuo Park in Nerima City. This large park was developed on the former site of a U.S. military facility, with an athletics field, a lawn plaza, and park paths lined with large trees. Use of the Splash Pond requires bare feet, so remove your footwear before entering. Admission is free, and there are restrooms in the park. In the morning, visit Nerima City Makino Memorial Garden, opened on the site where botanist Makino Tomitaro once lived, and walk through the woods of the adjacent Wako Jurin Park. For lunch, spread out a bento on the lawn of Oizumi Chuo Park, and in the afternoon, play in the Splash Pond until it closes at 15:30. This is a day tracing the western edge of Nerima, where traces of farmland and grove-surrounded homesteads remain.
