Where is it?
Hashima (or “Battleship”) Island lies off the coast of Nagasaki. In the late 19th Century, the Japanese discovered a method for extracting coal from the seabed. And the seabed around the Nagasaki islands was littered with veins of coal. Hashima was set up as a base of operations. At its peak in 1959, Hashima island had the highest population density ever recorded anywhere on earth, with 835 people per hectare packed into the high-rise living quarters.
Hey, where did everybody go?
From the 1960s, coal operations started shutting down all over Japan along with the rise of petroleum as the primary fuel source. Mitsubishi, who owned Hashima, closed the whole place down in 1974.
Why it’s scary as hell
The whole place is constantly raining rubble. Hashima has resisted any attempt at turning into a tourist destination because apparently, just going sightseeing turns into a level from an old platform game where you have to jump across gaps and dodge falling bricks.
Except you only get one life.
