Yamakuni River
| The Yamakuni River (山国川, Yamakuni-gawa) is a river that flows through the Ōita Prefecture in Japan. In its lower reaches it provides the boundary to the Fukuoka Prefecture to the west. The Yamakuni River arises on the slopes of the sacred Mount Hiko on the border of Oita and Fukuoka prefectures, flowing towards the sea through the Yabakei and Nakatsu plains, and empties into the Seto Inland Sea.[1] Tributaries include the Yamaoi River, Atoda River and Yamautsuri River. | ||||||
