On September 19 at 12 PM KST, EXID's Japanese debut album 'Up & Down' was released on various Korean music sites.

The album, which was released in Japan back on August 22, contained songs such as "Up & Down" Japanese version and remix version, "Cream" Japanese version, and Japanese original track "Vaporize Yourself!". Solji not only participated in recording all of the tracks in the album, but also returned to promotions in Japan for the first time since her hiatus through EXID's Japanese debut. 

"Hello. This is Banana Culture Entertainment. EXID's Japanese album 'Up & Down' released in Korea at 12 PM KST today was released without our consent, and we only discovered news of it through Karoma Music's press report. We at Banana Culture are currently looking into this situation, and we have asked Karoma Music to discontinue the distribution of the album in Korea. We apologize for causing confusion. We also ask for your continued attention toward EXID's future promotions. Thank you."
