Atami Sun Beach Water Park

Flow of the course

About this spot

A limited-season water park that appears on the water off the eastern side of Sun Beach, the symbol of Atami. In 2026 it runs from Saturday, July 18 to Sunday, August 30, with hours from 10:00 a.m. to 4:00 p.m. (reception until 3:15 p.m.), operating on a changeover basis in one-hour slots. Large floating slides, trampolines and balance equipment are linked together, so you can leap and bounce and really move your body. With the sea and streets of Atami as a backdrop, it is a special activity that only the summer holidays offer.

Season & hours

Tips

Because it runs on a changeover basis in one-hour slots, deciding your time slot before arriving cuts down on waiting. Wearing a life jacket is the basic rule, so it is reassuring to check in advance whether they are available to rent. Bring plenty of changes of clothes and towels.

Best time to visit

Entering around noon lets you enjoy it before the peak and play plenty through the afternoon
