The thing is, theres no way you can be really western without knowing the language. Yes, you can listen to msuic but would you understand the lyrics? I think the Japanese youth can only imitate the west in consumer products but its really difficult to, for e.g. understand western humour, customs etc. Being "G'd up" and "rolling on dubs" doesnt mean their even close to being hip hop as people in the US. Just making themselfs look stupid.
