Japan:Hashima Island(JP110)

Hashima Island , commonly called Gunkanjima, is one among 505 uninhabited islands in Nagasaki Prefecture about 15 kilometers (9 miles) from Nagasaki itself.
The island was populated from 1887 to 1974 as a coal mining facility. The island's most notable features are the abandoned and undisturbed concrete apartment buildings and the surrounding sea wall. The island has been administered as part of Nagasaki city since the merger of the former town of Takashima in 2005
