"Off the westernmost coast of Japan, is an island called "Gunkanjima" that is hardly known even to the Japanese. Long ago, the island was nothing more than a small reef. Then in 1810, the chance discovery of coal drastically changed the fate of this reef. As reclamation began, people came to live here, and through coal mining the reef started to expand continuously. Before long, the reef had grown into an artificial island of one kilometer (three quarters of a mile) in perimeter, with a population of 5300. Eventually, the mines faced an end, and in 1974 the world's once most densely populated island become totally deserted. The island, after all its inhabitants departed leaving behind their belongings, became an empty shell of a city where all its people disappeared overnight, as if by some mysterious act of God.
