The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Historical documents at the end of the Edo Period mention ash plumes from Yokoatejima. Yokoatesho (Yokoate Reef) and Kaminone Kaikyu (Kaminone Knoll) lie to NNW and NE of Yokoatejima, respectively. An arcuate ridge east of Yokoate-jima appears to be part of 7 x 10 km submarine caldera, with Yokoatejima and Kaminonejima to the NNE being post-caldera cones (Nakano et al., 2001-).
Higashimine, the high point of the island, has a steep-walled, well-preserved summit crater. Two peaks, Higashimine on the east and Nishimine on the west, form the andesitic island. Yokoatejima is a small, 3.5-km-long, dumbbell-shaped island NW of Amami Oshima Island at the SW end of the Tokara island chain.
