^Pauli. Rainie Yang releases Japanese version of "Youth Bucket" that fans do want. CpopAccess. 2010-02-02 [2013-07-07]. The English-based Kpop blogosphere has made it known to western fans of the huge popularity of Kpop over in Japan, but what has not been reported is that Kpop is actually only one of two popular trends going on over in the land of the rising sun. The other trend, of course, is Taiwanese pop. We kid you not, and there’s even a word for it Japanese called 台流 (pronounced Tairyū), which literally means the influx of Taiwanese pop culture in Japan.
