Kitakami River

The Kitakami River (北上川, Kitakami-gawa?) is the fourth largest river in Japan and the largest in the Tōhoku region. It is 249 kilometres (155 mi) long and drains an area of 10,150 square kilometres (3,920 sq mi). It flows through mostly rural areas of Iwate and Miyagi Prefectures. The river is unusual in that it has two mouths, one flowing south into Ishinomaki Bay and the other flowing east into the Pacific Ocean, both in Ishinomaki City. Another unusual feature is that there are no dams from its mouth to the Shijūshida Dam north of Morioka. This allows for a spectacular salmon run every fall.
