EXO-CBX will officially be debuting in Japan soon.
EXO's first ever subunit will be having their unit debut in Japan in May. On the subunit debuting in Japan, Xiumin said, "We really get along well, and we know each other well. The music we want to do is similar as well. It's our goal to meet many fans through fanmeetings."
It's unsure if they'll be having a new Japanese song or re-releasing "Hey Mama!" in Japanese, but stay tuned for more information.
