Looking at the abandoned ruins of Gunkanjima, the island in Nagasaki Prefecture seen in movies such as Skyfall, Battle Royale II, and the live-action Attack on Titan, it can be hard to imagine anyone living there. The structures, deteriorating even as their remains become overgrown with vegetation, have such an atmosphere of oppressive emptiness that it’s easy to forget it really wasn’t all that long ago that Gunkanjima, or Battleship Island, was home to a thriving coal mining community.
