Fashion in Japan

Japanese, young generation specially, are big pro-fashions. If you've visited Japan, you can understand what I mean from the bottom of your heart!
You know, Japan has been trying to keep its culture through fostering people as of childhood. Kimono, Yukata, and other folk dresses are still in use specially during national events and or ceremonies such as graduation,...
But the young people you see in the streets are huge pro-fashions. They come into public dressed in western style and with colored hair. If you ask me, I'll tell you that above 90% of them colorize their hair. Once I asked a Japanese friend, he said that he is doing this for the sake of his job as a waiter in a wedding salon. And he said that Japanese look the same as western people with colored hair.
The problem, however, is that they have their special face and head physiology. You will never take a Japanese as a western guy. Will you?
The other thing I'd like to mention is their clothing style. Here, in the southern part of the country, they wear mini joups during the cold and freezing winter (the temperature does not fall below zero but the cold winds are really killing), and for summer? Yes. You can see many of them with coats and weaven textiles and pants. Why? They say ""It is fashion".
