Former "Most Densely Populated Place on Earth" now decrepit wasteland

An old coal mining colony off the cost of Japan used to be the most densely populated place on earth. Once the mines shut down, all of the people fled leaving everything behind. It's illegal to set foot on the island - punishable by 30 days in jail - but these photographers managed to escape with some great shots.

From viceland.com:

These days the only things that land on Hashima Island are the shits of passing seagulls. An hour or so’s sail from the port of Nagasaki, the abandoned island silently crumbles. A former coal mining facility owned by Mitsubishi Motors, it was once the most densely populated place on earth, packing over 13,000 people into each square kilometre of its residential high-risers. It operated from 1887 until 1974, after which the coal industry fell into decline and the mines were shut for good. With their jobs gone and no other reason to stay in this mini urban nightmare, almost overnight the entire population fled back to the mainland, leaving most of their stuff behind to rot.
