The Chubetsu River has its source in Mt. Chubetsudake (alt. 1,963 m) in Biei Town and flows into the Chubetsu dam via the Tenninkyo Gorge, which is known as a scenic spot, and then merges with the Ishikari River. The Chubetsu River that flows on the south side of Asahikawa Station forms a river space coupled with the new station building completed in 2011 and the streets developed as part of the Kita Saito Asahikawa project.
