Premise: Even Japan's disaffected youth, normally sporting dyed hair, nose-rings, and torn T-shirts (and whatever else constitutes the latest street fashions to be slavishly copied), will attend an important festival in an expensive traditional costume, perhaps indicating that, despite their parents' concerns about their superficial appearance, some old values have not been entirely abandoned.

Hypothesis: Japan's youth often wear street fashions.
