Gunkanjima, Hashima Island, Battleship Island
Hashima Island, commonly called Gunkanjima, is an abandoned island of Nagasaki, lying about 15 kilometers (9 miles) from the center of the city. It is one of 505 uninhabited islands in Nagasaki Prefecture. The island's most notable features are its abandoned concrete buildings, undisturbed except by nature, and the surrounding sea wall. While the island is a symbol of the rapid industrialization of Japan, it is also a reminder of Japanese war crimes as a site of forced labour prior to and during the Second World War.
