I spent most of my time in Tokyo on my trip, and I have to say the fashion was awesome. Sure some stuff I didn't like, but at the same time most people were dressed to the nines. Most Japanese homes are quite small, ... so when getting together in groups.. most people go out to meet up. And when they go out, they dress up. For serious, I felt like a bum most of the time having my casual vacationing clothes on. Never been to another city where everyone is so well dressed before...
True, and it's not only in Tokyo, it's in every bigger City.
Japanese are total fashion maniacs, there's no place where you can see more people dressed in style. It's also great that even people that look kind of freakish still look very good, a thing that europeans (and especially germans) never manage to get.
