I found a site that links to some wonderful urban decay style photography from Japan
This search was inspired after reading Ryu Murakami's Coin Locker Babies. I wanted to find a real version of the "Toxitown" described in the book and found this!)
The link is here: Japanese Urban Ruins Galore!
(Clicking on the picture will lead you right to the collection, but I would suggest reading the paragraph under it first - because all text will be in Japanese after you leave that page.)
It's a great find, and I hope you guys enjoy it.
