Onikobe caldera is seen here from the SE. Onikobe, located SW of Kurikoma volcano, is one of the few calderas in Japan with evidence of ring fractures and a resurgent dome. Geysers were said to be discovered about 1700 years ago at Onikobe, and geysers and hot springs are present today within the caldera. The snow-capped Chokai volcano is visible on the upper right horizon.
