Hashima Island, commonly called Gunkanjima or Gunkanshima (Battleship Island), is an uninhabited island in the Nagasaki Prefecture about 15 kilometers from Nagasaki itself. The island’s most notable features are the abandoned concrete buildings and the sea wall surrounding it.
Once one of the most population-dense locations in the world, Hashima Island was abandoned in 1974. Today it is empty and has been dubbed Ghost Island. It remains a beautiful example of urban decay and abandonment.
