I will say from personal experience that Japan is one of the few places in the world I have seen many male fashion victims. To be clear, I enjoy expressive fashion, and I don't mean people who have an expensive or even outrageous or ovewrought sense of taste, instead I refer to those people who read multiple fashion magazines and wear ALL of the things.

Yes, definitely. Pick up the early FRUiTS books by Phaidon for a great, enlivening and colorful overview of 90s street fashion and youth. These images of creativity are what first got me really interested in traveling to JP.
