Musashino Stream, Tokorozawa Aviation Memorial Park

About this spot

This is the Musashino Stream in Tokorozawa Aviation Memorial Park (所沢航空記念公園) in Tokorozawa City. In 2026 it operates from Saturday, May 30 to Sunday, September 27, from 9:00 to 17:00. Operation may be suspended on short notice due to rain or other conditions, so keep an eye on the weather that day. Use is free, the park has restrooms and a shop, and a wide lawn adjoins the stream. Setting your belongings on the grass and taking turns watching, or running around the lawn when the children tire of the water, is the sort of thing only a large park allows. Since it runs until 17:00, you can play at a leisurely pace into the evening when the sunlight softens.

Tips

Because operation can be suspended suddenly, checking the day's status in the news section of the park's official website before setting out gives peace of mind. No changing rooms are listed, so bringing something you can slip on over a swimsuit, such as a rash guard, makes changing smoother. After water play, wash feet well at the taps and take breaks in the shade to prevent heatstroke. For children not yet out of diapers, please bring swim diapers.
