The Kikuchi River (菊池川, Kikuchi-gawa) flows through the northern part of Kumamoto Prefecture, Kyūshū, Japan. The source of the river is Fukaba, Aso city near Mt. Aso at the height of 1041 metres[1] and flows west through the Kikuchi Valley. It turns south near Kikusui and empties into the Shimabara Bay in the Ariake sea. Land reclamation is taking place at its mouth.[2] | ||||||
