Mount Ondake

Mount Ondake is a cinder cone volcano on Fukue Island in the Gotō Islands, rising roughly 315 meters above sea level. The mountain has steep slopes and a distinct crater at its summit that is visible from different parts of the island.

Mount Ondake formed through volcanic eruptions that shaped the Gotō Islands, leaving deposits of tephra and solidified lava. This volcanic activity significantly shaped the geological history of the entire island group.

Local residents of Fukue Island integrate Mount Ondake into their traditional stories about mountain spirits and natural phenomena.

To visit Mount Ondake, take a ferry from the mainland to Fukue Island and use local transportation to reach the mountain base. The climb is straightforward, though trails can be slippery after rain.

The mountain's layers clearly demonstrate how cinder cones form, with visible bands of volcanic ash and rock exposed on the slopes. This makes it easy for visitors to observe the geological process firsthand.
