Tomogashima

Tomogashima (友ヶ島^?) is a cluster of four islands in the Inland Sea, off Wakayama, Wakayama, Japan. The four islands are Jinoshima (地ノ島^?), Kamishima (神島^?), Okinoshima (沖ノ島^?), and Torajima (虎島^?). The islands form part of the Setonaikai National Park.

The islands were used by Buddhist monks for Shugendō. The folklore of the region holds that Ennogyoja, the founder of shugendo, underwent training on the steep cliffs of Tomogashima in the seventh to eighth centuries. This gave rise to the nickname of "The island of shugendo (mountain asceticism)" for Tomogashima.
