The Fuji River (富士川, Fuji-kawa or Fuji-gawa) is a river in Yamanashi and Shizuoka Prefectures of central Japan. It is 128 kilometres (80 mi) long and has a watershed of 3,990 square kilometres (1,540 sq mi). With the Mogami River and the Kuma River, it is regarded as one of the three most rapid flows of Japan. Water transportation up the river from Suruga Bay to inland Kai Province prospered in the Edo period and early Meiji period, until the opening of the Tōkaidō Main Line, Chūō Main Line and Fuji Minobu Railway railways. Commercial river transport ceased in 1923.
