Otofuke River

Japanese: 音更川 - おとふけがわ

A tributary of the Tokachi River that flows through the eastern part of Hokkaido. It is 93.5 km long and has a drainage area of 740 square km. It originates in the Ishikari Mountains, flows south, passes through the mountains, enters the Tokachi Plain near Shimizudani in Kamishiro Town under the jurisdiction of the Tokachi General Subprefectural Bureau, and merges with the main river near Obihiro. In 1953 (Showa 28), based on the Hokkaido First Comprehensive Development Plan, Nukabira Dam and a power plant (output 46,000 kilowatt-hours) were constructed upstream. The artificial lake is called Lake Nukabira.

Lake Nukabira
This artificial lake is located in the center of Kamishihoro Town. It was created when the Otofuke River was dammed up during the construction of the Nukabira Dam for hydroelectric power generation. The area is part of Daisetsuzan National Park, and virgin forests spread along the lake shore, which is over 30 km in circumference. Kamishihoro Town, Kato District, Hokkaido ©Fam. Kanagawa ">
