2026 Hokusei Park Wading Pool (北星公園 徒渉池) Full-Day Course

Hokusei Park (北星公園) in Kinsei-cho (錦西町), Tomakomai City (苫小牧市), has a multipurpose lawn area and a large play structure, so a whole day there never gets dull. Inside the park, the Hokusei Park Wading Pool (北星公園 徒渉池) is a free water-play spot open from Monday, May 25 to Wednesday, September 30, 2026, from 10:00 to 17:00. The venue is Hokusei Park in Tomakomai City, with a wading pool and fountains; the water is shallow, so even children who have just started walking can play within their parents' sight. Because the season runs from late May all the way to late September, a strength of this spot is that you can plan a visit outside the summer holidays. In the morning, first visit Tarumaesan Shrine (樽前山神社), a shrine set on a rise looking up at Mt. Tarumae (樽前山) and a place tied to the history of Tomakomai. Continue on to Nishiki Onuma Park (錦大沼公園), where the pondside cradled by forest lets you escape the heat of town. For lunch, move to Umi-no-Eki Puratto Minato Market near Tomakomai Port and enjoy seafood including surf clams, this town's specialty. In the afternoon, change into swimsuits and head to the Hokusei Park Wading Pool, splashing about until the 17:00 closing time. Mountains, forest, sea and water play connect in a single day, in a way that feels distinctly like Tomakomai.
