Hidaka Subprefecture (日高振興局 Hidaka-shinkō-kyoku?) is a subprefecture of Hokkaido Prefecture, Japan. The west side of the Hidaka mountains occupies most of the area. Hidaka is sparsely populated and has many of Hokkaido's natural resources. The governmental office is located in Urakawa.


  • 1897 Urakawa Subprefecture established
  • 1932 Urakawa Subprefecture renamed Hidaka Subprefecture.

The name Hidaka ('sun high') is derived from the province of the same name established in 1869, which in turn was named after an unknown place in the Nihonshoki, a history book written in 720. There is no direct connection between the Hidaka of the Nihonshoki and the modern Hidaka.


Located on the south-east coast of Hokkaido, Hidaka Subprefecture has an area of 4,811.91 square kilometres (1,857.89 sq mi) making it the 7th largest subprefecture in the prefecture and 5.8% of Hokkaido's total area. More than 80% of the area is covered with forest.

The prefecture borders Tokachi Subprefecture to the north across the Hidaka Mountains. To the west is Iburi Subprefecture. The south side of the subprefecture is its coast on the Pacific Ocean.[1]

The Hidaka Mountains are known as a "Mecca of Mountaineering", with more than 20 mountains including Mount Poroshiri at 2,052 metres (6,732 ft). These mountains are part of the Hidaka Sanmyaku-Erimo Quasi-National Park, which include Mount Apoi alpine vegetation community and Cape Erimo coast landscape. These areas boast wildlife such as brown bear, sika deer, and common seal.[2]
