"Fly" is Korean megastar BoA's latest Japanese single. As you undoubtedly know, BoA is a huge star in Japan as well as in her native Korea. In fact, if Wiki is up to date, BoA has released eight albums in Japan, whereas she's only released seven in Korea. That said, she's also released three EPs in Korea, which came early in her career. Suffice to say she's just as popular in Japan as she is in Korea. I don't know how she manages to juggle both countries and languages, but she does it, so I'd say she deserves the millions and millions of dollars she's made.
