2026 Idemitsu Culture Park Water Play Area (出光カルチャーパーク 水遊び場) Full-Day Course

Idemitsu Culture Park (出光カルチャーパーク) in the Suehiro-cho district of Tomakomai is a park that can be called the cultural heart of the city, with the municipal central library and the art museum standing side by side. The Idemitsu Culture Park Water Play Area (出光カルチャーパーク 水遊び場) inside the grounds is a free water play spot open from Monday, May 25 to Wednesday, September 30, 2026, from 9:00 to 21:00. The venue is Idemitsu Culture Park in Tomakomai, and because the water is shallow, even children who have just started walking can play within their parents' sight. Being open from late May to the end of September, and until 21:00 at that, makes it easy to choose both the time of day and the season, which is this place's great strength. In the morning, visit the Tomakomai City Museum of Art and History (苫小牧市美術博物館) in the same grounds, where the lives of the people who settled this land and art connected to Tomakomai are shown in one building. Then drop by the neighboring Tomakomai City Central Library (苫小牧市立中央図書館) and make time for your child to choose a book from the children's shelves. At lunch, move to an indoor shopping mall and spend the sunniest hours in the cool. In the afternoon, change into swimwear and return to the Idemitsu Culture Park Water Play Area to splash about until evening. Seeing, reading and playing: it is a luxurious way to spend a whole day within one park.
