Maruyama General Park Fountain Deck (丸山総合公園 噴水デッキ)

About this spot

The Maruyama General Park Fountain Deck (丸山総合公園 噴水デッキ) is a free water-play spot in Maruyama General Park in Kasai City. In 2026 it runs from Saturday, July 11 to Sunday, September 27, from 8:30 to 17:30. In a typical year it operates only on weekends and public holidays, and during the summer holiday period it runs every day except in rain. It is built around playing in water shot from the deck, so rather than swimming, the fun is running through the spray and enjoying the feel of the water hitting you. There is a management building, restrooms, and free parking, making the park very easy to use for families coming by car. It is open for a long stretch from 8:30 in the morning to 17:30 in the evening, so even if you spend the morning elsewhere, there is still plenty of time to play.

Season & hours

Tips

Admission is free. The operating days change with the season, so check the park's latest information before you set out. Changing space is limited, so wear swimsuits under clothes on the way and plan to dry off with a towel and change for the trip home, and you will have no trouble. Bringing one plastic bag per person for wet clothes makes the trip home more comfortable. During the strongest sunlight, take breaks in the shade and have children drink frequently.

Best time to visit

Get in at 14:00 and you can play for a full three hours, right into the evening when the sun softens
