The Hidaka Mountains (日高山脈, Hidaka-sanmyaku) are a mountain range in southeastern Hokkaido, Japan. It runs 150 km (93 mi) from Mount Sahoro or Karikachi Pass[1] in central Hokkaidō south, running into the sea at Cape Erimo. It consists of folded mountains that range from 1,500 to 2,000 m (4,921 to 6,562 ft) in height. Mount Poroshiri is the highest at 2,053 m (6,736 ft). The Hidaka Mountains separate the subprefectures of Hidaka and Tokachi. Most of the range lies in the Hidaka-sanmyaku Erimo Quasi-National Park (日高山脈襟裳国定公園, Hidaka-sanmyaku Erimo Kokutei-kōen). Since the mountain range lies so far north, the alpine climate zone lies at a lower altitude.
