Stratovolkan · Japan · 1624 m

Iwakisan rises above farmlands below its SE flank. The peak to the left is Chokaisan and the 2-km-wide summit crater is filled by a lava dome that forms the summit. Eruptions have occurred since 1597 CE and have consisted primarily of small-to-moderate phreatic explosions.
