Hidaka Mountains, Mountain range in Hokkaido, Japan
The Hidaka Mountains are a range in Hokkaido stretching from Karikachi Pass to Cape Erimo, with steep cirques and knife-edge ridges carved from crystalline schist. The system divides into northern, central, and southern sections, each offering distinct terrain and climbing challenges.
The mountains formed during the late Quaternary period through movements of the Kuril Island Arc and Northeast Japan Arc. These tectonic shifts created the rugged terrain and structure seen today.
The peaks have long held spiritual importance for the Ainu people, with Mount Poroshiri bearing a name from their language. This cultural connection remains visible through hiking traditions and how the land is respected by local communities today.
Hikers will find numerous trails in this range, though many lack clear markings and demand careful planning before setting out. Travel to the region is possible by bus, rental car, or train connections from New Chitose Airport.
The range holds over twenty glacial cirques at heights above 1,400 meters (4,500 ft), a feature that sets it apart from other Hokkaido mountain chains. These ice-carved basins formed in earlier cold periods and shape the distinctive landscape visible during a climb.
