The Ibo River (揖保川) is a river in Hyōgo Prefecture, Japan.[1] The Ibo, Kako, Ichi, Yumesaki, and Chikusa rivers are collectively referred to as the Harima Gokawa, the five major rivers that flow into the Harima Sea. The basin area is the second largest of the Harima Gokawa after the Kako River. The river originates from Mt. Fujinashi (elevation 1,139m) in Shisō, Hyōgo, and flows southward. It runs through Tatsuno and divides Nakagawa to the west near Yobeku, Himeji, forming a delta. | ||||||
