Held in both Osaka and Tokyo, Dream Party is a bi-annual event for bishoujo (beautiful young girl) computer games. This weekend, Dream Party rolled through Tokyo, filling the Tokyo Big Sight convention hall with cosplayers, figurines, computer games, and cars covered in nerdy decals.
Last year, cosplayers got in the way of the crazy cars; though, this year, that doesn't seem to be an issue. Phew! Hate it when people get in front of cars.
Check out photos of the cars (and cosplay) from websites AkibaOS and Asagawo Blog.
