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. 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, Dangyokei and Jōsei Falls around the region of the river.[1][6][7][8]
It is known for ukai (鵜飼い) or cormorant fishing for ayu, which can be found especially in Miyoshi, Hiroshima. According to one theory ukai in Miyoshi has taken place since late Sengoku Period, and is now one of the tourist attractions of the city.[4][9][7]
