During the group’s final concert at Saitama Super Arena, Atsuko made the announcement during the encore saying, “I took the audition to enter AKB48 when I was 14 years old, which was a big decision in my life. Now, please let me make my second big decision. I am graduating from AKB48″
At this point there are no details about her graduation, but she promises to reveal those details once things are decided.
Best of luck to Atsuko in all of her future endeavors.
