About this spot

In 2026, the “Hirowatari Dam Lakeside Park Pool” in Nichinan City, Miyazaki Prefecture runs in two sessions per day from Saturday, August 1 to Sunday, August 30. Its defining feature is a roughly 800-square-meter natural pool filled with water from the Hirowatari River, offering a cool sensation quite different from a pool heated from tap water. The 70-meter-long waterslide is thrilling and popular enough that riders line up again and again. With changing rooms, restrooms, lockers, an eatery, and parking for 70 cars, families can relax with peace of mind. Swimming surrounded by the reservoir and mountain scenery is an experience unique to this spot.

Tips

Since the pool runs in two sessions, check the times and the changeover process for the morning and afternoon sessions before you leave. Because it uses river water, your body cools quickly, so plan to get out and rest often for safety. There's an eatery on-site, so you can get lunch there. The pool may close depending on the weather, so check ahead on rainy days.
