2026 Shimo 4-chome Children's Park Water Play Area Full-Day Course

This is a free, full-day outing course centered on the Shimo 4-chome Children's Park Water Play Area (志茂四丁目児童遊園 水遊び場) in Shimo, Kita Ward (北区志茂). For the 2026 season, it is open from Tuesday, July 21 to Monday, August 31, 10:00 AM to 4:00 PM. This water play area has no scheduled cleaning closure days, making it easy to plan a visit any day during summer vacation. The Shimo 4-chome Children's Park Water Play Area is located in a quiet residential area, about a 10-minute walk from Shimo Station (志茂駅) on the Tokyo Metro Namboku Line. In the morning, learn about the history of the Arakawa River and its floods at the Arakawa River Museum 'Amoa' (荒川知水資料館アモア), then visit the nearby Former Iwabuchi Floodgate (旧岩淵水門), commonly known as the Red Gate (赤水門). This spot, where the Arakawa and Sumida Rivers diverge, offers a rare view that makes clear at a glance the relationship between Tokyo's water and daily life. For lunch, enjoy a lively meal at Akabane Ichibangai Shopping Street (赤羽一番街商店街), and in the afternoon, splash around at the Shimo water play area. It's a day unique to Shimo where learning and play flow naturally into one another. Since the facility may close suddenly due to weather or other circumstances, be sure to check Kita Ward's official website for the day's operating status before you set out.
