Yokoate-jima

Yokoate-jima is a volcanic island in the Tokara Islands, rising about 495 meters (1,624 ft) above sea level and shaped by two stratovolcanoes with forested slopes and steep coastal cliffs. The shoreline extends roughly 10 kilometers (6 mi) around the island, displaying striking rock formations at various points.

The island experienced its most recent volcanic activity during the final years of the Edo period around 1835, marking the end of its active geological phase. This eruption was among the last major volcanic events recorded in the region.

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

A visit requires careful planning since access depends on the Toshima ferry schedule and the island lacks developed infrastructure. Bring all necessary supplies and prepare for limited facilities.

The island contains two calderas at different elevations: Higashimine peaks at around 494 meters (1,621 ft) while Nishimine reaches only about 259 meters (850 ft). This geological variety reflects the complex volcanic history of the place.
