Akihabara.. What a strange part of Tokyo. I walked through once, I wasn't to impressed. The place is creepy. The only good place I saw was that main shoping center as soon as you get off of Akihabara Station.
Plus there are a bunch of wierdo and psycho's there. Some guy just went on a murder rampage a month ago.
