Course
From the mountain Oizaridake, the Toyohira River flows northwards into Lake Jōzan (定山湖, Jōzan-ko?). The Hōheikyō Dam (豊平峡ダム, Hōhei-kyō Damu?) created the lake. The river runs through the gorge. After exiting the gorge it is joined by several more rivers before turning East. Two smaller dams block the course of the Toyohira as it moves into the suburbs of Sapporo. The river flows north and east through the middle of the Toyohira Ward of Sapporo. As it leaves the urban area it forms the border between Sapporo and Ebetsu before emptying into the Ishikari River.
