Kyle Merriman recently visited Nara Dreamland, the abandoned Disneyland knockoff theme park in Nara, Japan that was built in 1961 and closed in 2006. He found it to be fairly intact, except for the fact that there are no people there and the weeds have grown everywhere. See the state of the park in a gallery of 56 photographs. Link
