Tōno is located in central Iwate Prefecture, in the floodplain of the Sarugaishi River, surrounded by a ring of mountains. Mount Hayachine sits at the northernmost point of the city where Hanamaki, Kawai and Tōno meet. At 1,914 meters it is also the city's highest point. Mt. Rokkoushi, (1,294 meters) dominates the landscape to the east and Mt. Ishigami (1,038 meters) is the highest mountain in the west. Together these peaks form Tōno's "big three" mountains. The highest points in southern Tōno are Mt. Sadato (884 meters) on the border of Sumida and Mt. Tane (871 meters) on the borders of Sumita and Ōshū.
Accordingly, to legend, in the past the hills in Miyamori blocked the Sarugaishi River creating a large lake in the Tōno area. Miyamori itself is characterized by a series of valleys to the west of Mt. Ishigami that flow west into the Sarugaishi River just below the Tase Dam.
