OMG Chinese and Japanese people LOOOOOOOVVVVVVEEEEE reggae and dancehall since the beginning of dancehall they have been rocking with it. Artists have gone to Japan especially since the early 90s and sold out tours over there. A few years back the dancehall queen was a Japanese girl who couldn't speak a lick of english. In all the dancehall DJ competitions called cup clash there is always a Chinese Japanese competitor (black spider and mighty crown). They know all the dances and all the words and everything.
this video shows a jamaica day concert skip to about 5 mins in to see the girls dancing on stage. It's a bit awkward to watch some of them but eh.
