Abandoned Japanese Buildings
Via Bryan's Basement, an interesting link to many pictures of abandoned Japanese buildings. Bryan made exactly the comment I would have, expressing surprise that these sites had not been rebuilt or recycled in some way, given the scarcity of land in Japan.
My favorite was this abandoned amusement park (at least I think that's what it is), including the creepy Gulliver lying before Mt. Fuji (see in extended entry).
