Onagi River

A river that flows through the northern part of Koto Ward, Tokyo. It is a canal that connects the Sumida River and the Nakagawa River as a boat route for transporting Gyotoku salt (Gyotoku is located in Ichikawa City, Chiba Prefecture) to Edo, and was opened shortly after Tokugawa Ieyasu entered Edo. Later, as land reclamation progressed in the Fukagawa area, the riverbank was renovated, and it became the present Onagi River (4.6 km long). From the Nakagawa River, it connects to the Funabori River to the east, connecting the Edo River and the Sumida River, and was a major artery for ships traveling eastward to carry goods to Edo via the Tone River and Edo River. JR Onagawa Station, located in Kitasuna, played a part in transportation as a freight station, but was closed in 2000.

東京都江東区(こうとうく)北部を流れる川。行徳塩(ぎょうとくじお)（行徳は千葉県市川市）を江戸に搬入する舟路として隅田川(すみだがわ)と中川とを結んだ運河で、徳川家康江戸入府後まもなく開通した。のちに深川方面の埋立てが進展して川岸が改修され、現在の小名木川（延長4.6キロメートル）になった。中川から先は東の舟堀川に結ばれて江戸川と隅田川が通じ、東廻(まわ)りの船が利根(とね)川、江戸川を経て江戸へ物資を運ぶ大動脈であった。北砂にあったJR小名川駅は貨物駅として輸送の一端を担っていたが、2000年廃駅。
