Enjoy 25-meter pool, lazy river, and water slides until evening

About this spot

A 2026 outdoor leisure pool in Wataraicho by the Miyagawa River, operating from July 18 (Saturday) to September 6 (Sunday), 9:30 AM to 4:00 PM. In addition to the sturdy 25-meter pool, there's an infant pool safe for small children, a lazy river pool where you can drift peacefully on a float, and a water slide, allowing every family member to enjoy at their own pace. The location by the Miyagawa River surrounded by lush greenery offers an openness that differs from urban outdoor pools. Please note that the fountain pool and water tunnel will be closed in 2026. If you enter in the early afternoon, you can enjoy water play until the facility closes at 4 PM. Entry time in the early afternoon allows for plenty of time to enjoy water activities.
