Sapporo-dake, Mountain summit in Minami-ku, Japan.

Sapporo-dake is a mountain in Minami-ku on Hokkaido with forested slopes throughout its elevation. The trails wind through woodlands and pass through different zones of vegetation as they climb toward the summit.

The mountain's name comes from the Toyohira River, whose headwaters rise here; before the Meiji era the river was called Sat Por Pet, Ainu for "dry great river", the source of Sapporo's own name. The Toyotaki route was once used for devotional climbing. The first Reisu Hut burned during the Pacific War and was rebuilt in 1952 by Hokkaido Electric Power, reportedly as compensation for building power lines through Shikotsu-Toya National Park.

The name comes from the Ainu "Sat Por Pet", meaning "dry great river", the source of the Toyohira River that flows through Sapporo. The Toyotaki route was once used for religious climbing, and a stone Buddha sits on the lower Cold Water Stream route. A stone monument to Ishizuchi Shrine stands on the summit.

Two marked routes start from the trailheads: the Reisuizawa course near Toyohirakyo Dam, with a large car park and a small log hut for submitting a climbing notice, and the Toyotaki course along the Bannosawa forest road, which is not maintained every year and can be overgrown. The Reisuizawa course crosses Reisuizawa stream repeatedly before a flat larch plantation, then climbs steeply past the Reisuizawa hut at 860 m. From the ridge the way to the summit is flat, but the final climb from the junction with the Toyotaki course gains 160 m.

The summit holds a stone monument to Ishizuchi Shrine and a first-order triangulation point marked "Sapporo-dake". The mountain's name comes from the Ainu "Sat Por Pet", meaning "dry great river", the old name of the Toyohira River whose source lies here.
