The participating members were chosen by AKB48's 2011 general election. Each of AKB48's 21st single "Everyday, Kachusha" contained a ballot that allows the buyer to register a vote for one of the member candidates for the group's 22nd single. The top 21 vote-getters would get to participate in the title track, and the top 12 from the lineup would be prominently featured in its promotions. The winner of the general election was Atsuko Maeda, with Yuko Oshima as runner up. The members who were ranked 22 to 40 were grouped as "Under Girls" and recorded on one of the B-sides.
