“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, [with] the chance discovery of coal … people came to live here, and through coal mining the reef started to expand continuously. Befor [sic] long, the reef had grown into an artificial island of one kilometer (three quarters of a mile) in perimeter, with a population of 5300. Looming above the ocean, it appeared a concrete labyrinth of many-storied apartment houses and mining structures built closely together.
