Onikobe volcano is a caldera SW of Kurikoma volcano in northern Honshu, Japan. It is probably extinct, but there are prominent geysers and hot springs in the caldera, known since about 1700 years ago.
In 1938 a new geyser (Benten geyser, or generally called Onikobe geyser) formed at a site where local residents had dug a borehole to create an onsen (hot spring).
