Tomogashima Islands

Tomogashima Islands lay on the Kitan Strait in northwestern Wakayama. It consists of four uninhabited islands: Jinoshima, Torajima, Kamishima and Okinoshima.
Okinoshima was once used by the Japanese military as a base, and still has ruins of fortresses and ammunition depots. This scenery is reminiscent of that in the 1986 animation film “Castle in the Sky”, and because of that, the island is referred to as “Laputa Island”.
By going on the 1.5-hour hike, you can see the major ruins on the island, such as the lighthouse, fortresses and observatory. The third fortress, in particular, is the largest of the six fortresses on the island.
