About this spot

The Tokumochi Park Water Play Area (Waterfront Facility) is a free water-play spot at Tokumochi Park in Ota City. In 2026, the season runs from around Monday, April 27 to around Wednesday, September 30, operating from 10:00 to 16:00. The facility is a waterfront facility with a pond and stream, with water that's filtered and disinfected, though it's not drinkable. You can play by walking along the stream, so it suits both small children who play sitting still and older children who want to run around. Admission is free, and being within walking distance of Ikegami Honmon-ji Temple is a convenient feature of this park. Don't expect changing space, so wearing your swimwear under your clothes will shorten your prep time.

Tips

It's closed for regular cleaning on August 6, August 14, and August 24. Since the closing date isn't officially announced by the ward (late September in past years), check in advance if you're going in September. It may not operate on rainy days or when the temperature is low. The water is filtered and disinfected but not drinkable. A guardian must accompany children, and don't forget to hydrate after playing.
