Mt Ishikari

Mt Ishikari (Japanese: 石狩岳) is a nihyakumeizan* that stands deep within the Central Ishikari Mountains of Hokkaido, a non‑volcanic uplifted range forming part of the western sector of Daisetsuzan National Park. It is the highest peak of the Ishikari range and one of the most remote, deeply carved mountains in central Hokkaido. Its topography is rugged and alpine in character with steep ridges, deep valleys and a summit area shaped by long erosion rather than volcanic activity. 

​

Mt Ishikari forms a major watershed divide between the Pacific and the Sea of Japan, and it is the source of the Ishikari River, the longest river in Hokkaido. Because it occupies the deepest interior of the East Daisetsuzan region, early explorers regarded it with particular awe. It is as far from the sea as you can get in Hokkaido, and the second furthest in Japan.

​

The views from the summit are expansive and wild. To the northeast, the ridge runs toward Mt. Otofuke (音更岳) to the southwest, it links with Nipesotsu (二ペソツ山) and the long East Daisetsuzan chain. Because the mountain stands at a major watershed, the panorama includes both the Pacific‑side Tokachi basin and the inland highlands of Kamikawa. 

​

The hiking is long, steep and rewarding. It was one of the most arduous and thrilling hikes I did in Hokkaido. The classic Schneider Course, which I took,  climbs from the Mitsumata area, rising sharply through forest before a sustained ascent that leads directly to the upper ridges. The route typically takes 6–7 hours to reach the summit, with loose rock, steep slopes and long stretches above the treeline. Alternative approaches via Otofuke-dake or longer traverses toward Nipesotsu offer multi‑day alpine journeys through some of the most remote terrain in Daisetsuzan. Despite its rugged reputation, the mountain is well‑loved by experienced hikers for its solitude, strong alpine character and superb ridge walking. It is a habitat to a significant number of brown bears so hikers should be well prepared.
