Outline of Kamanashigawa Branch Office
The Kamanashi river upper reaches Sabo was started with the establishment of the Kamanashigawa Plant at Ochiai mura.
By 1935, construction of 3 Sabo dams and a groundsill at tributaries, hillside works and bank protection works at main stream were completed.
Furthermore, construction of sediment control Sabo dam, the Karasawa dam, was started in 1936 for the first time.
After the blank years during the World War, the project has resumed on a full scale under the direct jurisdiction of the Kamanashigawa buranch office.

Geologically weak soil and deep valley along the river
The Kamanashi river takes its source from Mt. Nokogiri(2,607m) and its upper stream runs between steep cliffs. This area is geologically weak due to complex faults and weathering rocks along the river.

Beautiful scenery of Fujimi that have fascinated poets and artists
Upper stream of the Kamanashi river, source of the Fuji river which is one of the three most rapid streams in Japan, separates the area into two towns, Fujimi-cho at its left and Hakusyu-cho Hokutoshi at its right. While Fujimi-cho is famous for its beautiful scenery as it has attracted many poets and artists, Hakusyu-cho Hokutoshi is mountainous and there is only one village in the town. Under such situation, people living in Hakusyu-cho need to have a close relationship with Fujimi-cho.
