well first of all japanese may use sythetic wood since they have that kind of technology..this is somethig you want if u want sustain(how long notes go)..it can be ridiculosu though....string stuff that you dont want to hear comes in and you hve to be advanced at mutting other stings while playing..



thats the main point pretty much...they may not use floyd rose either and have differnt pickups..but wood is the main difference
