2026 Arai Yakushi Park Wading Pool: A Full Day Course

In Nakano Ward's Arai Yakushi Park, there is the Arai Yakushi 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 52.6 square meters and is about 35cm deep, making it especially spacious among the wading pools in Nakano Ward, with plenty of room to play freely. The water is tap water, changed daily and managed with chlorine, so it is safe from a hygiene standpoint as well. 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 Arai Yakushi Park Wading Pool in Nakano Ward, and admission is free. In the morning, visit Arai Yakushi Baishoin, which stands right next to the park, then learn about the area's past at the Nakano City Museum of History and Folklore. For lunch, spread out your bento at the deeply green Egota no Mori Park, then enjoy plenty of water play in the afternoon session, that is how the day unfolds.
