Ōu Mountains
Shizukuishi is located in the Ōu Mountains of west-central Iwate Prefecture, bordering Akita Prefecture to the west. Mount Iwate (2038 m), an active volcano, lies just to the north of Shizukuishi and dominates the landscape. The Ōu Mountains form the boundary to the west as well with Akita Komagatake, another active volcano, just across the border in Akita Prefecture. The downtown area is located where the Shizukuishi and Kakkonda Rivers meet. Gosho Lake was created in 1981 with the completion of Gosho Dam.
