The Iwate volcano-complex is situated in the northwest of the city Morioka in the western part of the Iwate Prefecture. It is part of the Towada-Hachimantai National Park.
The Mount Iwate consists of a younger eastern symmetrical stratovolcano (Higashi-Iwate, "East Iwate"), which is overlapping an older western stratovolcano (Nishi-Iwate, "West Iwate"). The oval-shaped, 1.8 x 3 km caldera, has a central cone containing a 0.5 km wide crater, partially filled by a crater lake. The mountain is listed as one of the 100 Famous Japanese Mountains.
