2026 Keyaki Park Wading Pool: A Full Day Course

In Nakano Ward's Keyaki Park, there is the Keyaki Park Wading Pool, where you can play in the water for free during summer. In 2026 it operates from Saturday, July 18 to Sunday, August 16, from 10:00 to 16:00. It runs in two sessions, 10:00-12:00 and 13:00-16:00, and is closed at midday for the water change. The pool covers 21.2 square meters and is only about 20cm deep, shallow enough for children just learning to walk to stand on their own feet. The water is tap water, changed daily and managed with chlorine, so you can let children in with peace of mind about hygiene. It closes on rainy days and when the water temperature is 22C or below, so keep an eye on the weather that day. The venue is Keyaki Park Wading Pool in Nakano Ward, and admission is free. In the morning, look up at the three-story pagoda at Hosen-ji Temple in Nakano-sakaue, then peek into Nakano Broadway, known as a mecca for subculture, before heading to the afternoon water-play session. This is a classic Nakano-style summer outing that can be completed entirely by train and on foot.
