about the same or more.. it was actually cheaper for my cousin to have parts shipped from the US to him in S. korea then it was to fly order from japan..
now if you live in japan.. the parts are cheap.. but if your an outsider going to japan.. they are expensive as hell.. because japanese workers get payed a ton more money then we do in the US and our inflation amounts are different plus on top of that converting the weak USD to the japanese yen..
