The Gōnokawa River (Japanese: 江の川(ごうのかわ/がわ), Hepburn: Gōnokawa/Gōnogawa) is a river that runs through Hiroshima and Shimane prefectures in Japan. It is the largest river in the Chūgoku region. It is also called the Gōgawa River (江川(ごうかわ)) and, in Hiroshima, the Enokawa River (可愛川(えのかわ)).[5][1] The mainstream originates from Mount Asa (阿佐山) located in Kitahiroshima, Hiroshima (former Geihoku). Its three tributaries including Basen River (馬洗川), Saijō River (西城川) and Kannose River (神野瀬川) flows into the mainstream in Miyoshi Basin [ja]. The gradients being relatively gentle, the river had been commonly used for boat transport until 1930s, when Sankō Line and trafficways were built and opened. There are some valleys and waterfalls such as Senjōkei [ja], Dangyokei [ja] and Jōsei Falls [ja] around the region of the river.[1][6][7][8] | ||||||
