I don't know, it seems to me that in the Western world, parents try to talk to their kids, or try to go counselling or something. It does not always work but they are not usually passive about it. In Japan there is virtually no dialog - probably because there is so much respect for the "private sphere" of the individual.

That's also why in Japan you never have "deep" discussions with anyone. All the stuff you talk with people is very, very superficial. Or maybe its just my impression.
