Ever heard of Hashima Island? It's a japanese offshore island about 15 Km from Nagasaki. It's also called Gunkanjima Island because from a side view it looks somewhat like a battleship. It was originally used as a coal mining facility under the control of Mitsubishi and was officially closed in 1974 and has been falling appart since.
Now, why am I posting a thread about this? Because it totaly reminded me of Kowloon when I saw pictures of it. And the best thing, you can explore the island with all it's ghost buildings in Google Street View! So try it out and take in the awesome eerie atmosphere.
