T-ara’s 2nd Japanese single, Yayaya, made it to the #7 spot on Oricon Chart. Not bad, but both the position and sales numbers dropped quite a bit from Bo Beep Bo Beep (#1).
I think the biggest reason is the lack of promotion in Japan. AFAIK T-ara only had one showcase for YaYaYa whereas there’s series of publicity for Bo Beep Bo Beep.
It’s a bit greedy to release a Korean album and Japanese album at the same time. I hope their company learn the mistake and manage their schedule better next time.
