Gunkan-jima, meaning "battleship island" in Japanese, is the nickname of several islands:
Hashima Island (Japanese: Hashima), Nagasaki Prefecture, Japan
Mitsuke-jima, Suzu, Ishikawa, Japan
A highlight along the inner coast is the Mitsukejima rock. Mitsukejima means "found island", and according to legend it was first discovered and named over a thousand years ago by Kobo Daishi, one of the most important figures of Japanese Buddhism. The island extends about 30 meters into the air, towering over the travelers who walk along the rock path to get a closer look. There is a bell nearby that brings good luck to lovers if they ring it together.
