Including the main peak Wagadake (1440 meters), Yakushidake (1218 meters), Shiraiwadake (1177 meters), Mokkodake (1278 meters), Nakanosawadake (1013 meters) and other mountains over 1000 meters above sea level are connected from north to south.
The area of the Waga Mountains extends from the Seniwa Pass (Semboku City) in the north to the Maki Valley (Daisen City) in the south, the upper reaches of the Waga River (Nishiwaga Town, Iwate Prefecture) in the east, and the Dakigaeri Valley in the west. The Waga Mountains form a mountainous area of about 30,000 hectares centered on the prefectural border ridge between Akita and Iwate, and the untouched native natural area area without human intervention such as deforestation and forest road construction is almost undivided. It covers an area of approximately 15,000 hectares.
In addition, the headwater area, which is derived from the integrated ridgeline to the entire mountain area, is filled with a stable and abundant amount of water, making it a rich natural body.
