Isawa River
| The Isawa River (胆沢川, Isawagawa) is a river in Iwate Prefecture, Japan. For about half its length it marks the border between Kanegasaki Town and Ōshū City. The river's origin is in the Ōu Mountains just west of Mt. Yakeishi (1548 meters). At its highest point it is called the Sugiyachi Stream (スギヤチ沢, Sugiyachizawa) and flows south until it crosses National Route 397. There it turns west and follows 397 until it is stopped by the Ishibuchi Dam.[1] | ||||||
