Rishiri is a highly dissected andesitic stratovolcano that forms an island west of the northern tip of Hokkaido. The main edifice ceased erupting during the Pleistocene, and extensive erosion has created a rugged dissected summit flanked by radial knife-edged ridges. Scoria cones and maars on the lower flanks have been active during the late Pleistocene and early Holocene.

Rishiri volcano is a highly dissected stratovolcano that forms an island off the NW tip of Hokkaido. The composite cone (center) and flank scoria cones (middle ground) are mirrored on the surface of a maar on the lower south flank. The stratovolcano was constructed during the Pleistocene. Scoria cones and maars on the lower flanks erupted 30,000-8,000 years ago.
