Hey there,
i recently heard about Hashima island. So i had to make some research and found some cool stuff i would like to share with you!
Hashima or also called "Battleship Island" (because of it´s shape) has for sure something eerie about it.

located about 15 km from Nagasaki in Japan. 
Hashima Island - 端島, or Hashima or commonly called Gunkanjima (軍艦島, what equals Battleship Island
The Island was established in 1887 for undersea coal mining. Hashima was meaningful throughout the growing industrialisation around 1900.

It became a darker meaning during WWII around 1930 when forced laborers from Korea or China where forced to work there under harsh conditions.

Also after the war and until 1974, the island was still populated up to 5000 Japanese laborers before the mines started to run out of coal.

Soon, all the population was departed and the island was left abandoned for the next 30 years an nature took over.
Today the island is open for tourists. But you are not allowed to walk around freely and enter the buildings. You must stay on the touristic paths because the crumbling buildings might collapse. Don´t worry though, you do not have to put yourself in danger, you can actually visit Hashima through your computer!
Google street view offers you a tour around the island.
