F(x) Japanese Debut

Okay, don't get confused this is a k-pop blog speaking about a k-pop group. On the eastern side of the world, Japan is the music central, the place you wanna be. Most k-pop groups promote in Korea for about 3 years and then move to debut in Japan.
When promoting in Japan, the idols remake most of their Korean songs and promote those along with their original Japanese songs; sometimes they remake their Japanese song into Korean. Once debuted in Japan, they promote in both countries.
Even though they primarily promote in Korea and Japan, they also promote in other Asian and non-Asian countries (examples: US, China, and Thailand), singing their songs in its original language.
