Mount Iwate (岩手山 Iwate-san?) is a stratovolcano complex located northwest of the city of Morioka in western Iwate Prefecture, Tohoku, Japan. The mountain is listed as one of the 100 Famous Japanese Mountains in a book composed in 1964 by mountaineer/author Kyūya Fukada.
Mount Iwate consists of a younger eastern symmetrical stratovolcano (Higashi-Iwate, "East Iwate") overlapping an older western stratovolcano (Nishi-Iwate, "West Iwate") which has collapsed to form a caldera. 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.
