Hashima Island, or Gunkanjima - the Battleship Island. Battleship Island is an English translation of the Japanese nickname for Hashima Island, Gunkanjima (gunkan meaning battleship, jima being the rendaku form of shima, meaning island). The island's nickname came from its resemblance to the Japanese battleship Tosa.
Gunkanjima is one of 505 uninhabited islands in Nagasaki Prefecture. The island's most notable features are its abandoned concrete buildings, undisturbed except by nature. The small island was known for its undersea coal mines, established in 1887, which operated during the industrialization of Japan. The island reached a peak population of 5,259 in 1959. In 1974, with the coal reserves nearing depletion, the mine was closed and all of the residents departed soon after.
The island was formally approved as a UNESCO World Heritage Site in July 2015, as part of Japan's Sites of Japan's Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining.
External shots of the island were used in the 2012 James Bond film Skyfall.
