KAT-TUN member, Taguchi Junnosuke, upset some fans during their live concert at the Tokyo Dome on July 25th.
At the beginning, when the members were talking about co-starring with other members in dramas, Kamenashi Kazuya asked Taguchi if he had ever co-stared with any KAT-TUN members in a drama, and Taguchi answered that he has never done it. However, Taguchi did co-star with Akanishi Jin in "Yukan-club" in 2007.
Perhaps the KAT-TUN members made it a point to not mention Jin during the concert on purpose?
Regardless, after the concert, some fans complained on the Internet about the comment Taguchi made, stating that it represented a mistreatment of Jin because Taguchi referred to Jin as if he was never a member of KAT-TUN.
