Fuefuki River

The Fuefuki River has its source the neighboring mountains of Mount Kobushi on the southern slope of Mount Kobushi in the north of Yamanashi, on Honshu, in Japan.^[1][2] Its course takes a southeast direction to the Hirose dam then south, in the east of Yamanashi. Leaving Yamanashi, it successively crosses the northwest of Fuefuki to which it gives its name,^[3] south of Kōfu, central Chūō and the northwest of the town of Ichikawamisato. Near the boundary between Ichikawamisato and Fujikawa, the Fuefuki and Kamanashi rivers^[1] converge and form the Fuji River.^[4][5]

The watershed of the Fuefuki River covers an area of 1,040 km² (400 sq mi) in the northwest of Yamanashi prefecture.^[2]
