About this spot

The Idemitsu Culture Park Water Play Area (出光カルチャーパーク 水遊び場) is a shallow water play spot in Idemitsu Culture Park in Tomakomai. In 2026 it is open from Monday, May 25 to Wednesday, September 30, from 9:00 to 21:00, and use is free. The long season from late May to the end of September, plus opening hours that run until 21:00, put it well ahead of the other water play spots in this city. The water is shallow, so even children who have just started walking can stand on their own feet and play, which is reassuring. Because the municipal central library and the art and history museum are in the same grounds, you can escape indoors if it rains, and that peace of mind is this park's greatest strength. It is close to the city centre, so you can drop in easily after shopping or a meal and head straight home once you have finished playing.

Season & hours

Tips

Opening hours are 9:00 to 21:00. It may close due to bad weather, cleaning or water quality management, so check the Tomakomai city information for the day's status before you set out. Assume there are no changing rooms and wear swimwear underneath to make changing easier. It stays open into the night, but footing is hard to see after dark, so decide in advance when you will get out. Shade is limited to the area around the trees, so bring a picnic sheet, hats and a light layer to put on afterwards.

Best time to visit

Arrive at 14:30 and you can play for three hours. Evening, when the sun softens, is the most comfortable time
