Nariwa River

Japanese: 成羽川 - なりわがわ

Dogoyama (1,269m) on the border between Hiroshima and Tottori prefectures, flows southeast, and empties into the Takahashi River in western Okayama Prefecture. It is the largest tributary of the Takahashi River, with a total length of about 80km. The upper reaches are called the Tojo River, and the river basin was once a producer of iron sand. It carves a V-shaped valley in the Kibi Plateau. The Shinnariwa Dam and Tahara Dam were built in Takahashi City, Okayama Prefecture, and supply industrial water to the Mizushima coastal industrial area. The Taishaku Gorge of the Taishaku River, a tributary in eastern Hiroshima Prefecture, is a scenic spot. The Kasagami Mojiiwa Rock near the Shinnariwa Dam is a valuable historical site that shows that shipping had already reached this area during the Kamakura period.

広島，鳥取県境の道後山 (1269m) に発して南東流し，岡山県西部で高梁川に注ぐ川。高梁川最大の支流。全長約 80km。上流は東城川と呼ばれ，流域はかつて砂鉄の産地であった。吉備高原にV字形の谷を刻む。岡山県高梁市に新成羽ダム，田原ダムが建設され，水島臨海工業地域へ工業用水を供給する。広島県東部にある支流帝釈川の帝釈峡は景勝地。新成羽ダム付近にある笠神文字岩は鎌倉時代すでにこのあたりまで舟運のあったことを示す貴重な史跡。
