Yokoate-jima

Yokoate-jima stands 495 meters above sea level, featuring two distinct stratovolcanoes with forested interiors and steep cliffs along its 10-kilometer coastline.

The island recorded its most recent volcanic activity during the final years of the Edo period, approximately around 1835, marking its last geological transformation.

The island forms part of Toshima village, which extends across 160 kilometers of ocean, making it the longest administrative village division in Japan.

Visitors require careful planning as access depends on the Ferry Toshima schedule, and the island lacks infrastructure, necessitating personal supplies for exploration.

The island contains two calderas with different elevations: Higashimine reaching 494 meters and Nishimine at 259 meters, creating a distinctive geological formation.
