Not only in Japan but in world wide, New Pop Culture is continuously born in the world by young people.
There are many ways to know what pop culture is but on this blog, I will concentrate on fashion in Japan.
I would say that Japanese young fashion has some kind of different favor compared to foreign young people because
Japanese fashion has various ways to express their characteristics.
such as as you can look at this fashion store fake tokyo, they have some kind of punkish style.
on the other hand, haight and ashbury has old european sense of fashion.
so Why do they wear like these??
I think because they want to express what they want to look like, and what kind of music or sense they like by showing thier characteristics through fashion.
For example, In japan, models who used to be ordinary girls became models is a new way to become popular models.
AMO is a popular model in Zipper and Kera.
Although she was an ordinary girl, she became a popular model. and mainly popular among harajuku girls.
The way she expresses her characteristics is the great example of how common harajuku girls do.
because she likes fantasy, gothic, pastel colors, and classical things so as you can see from her blog, her fashion is exactly showing what she likes.
So I would say that japanese fashion is a useful tool to show what they like and what kind of person he/she is.
