Yuko Oshima, 23, of Japan's girl pop group AKB48, appears on a screen after being crowned its favourite member at an annual popularity "election" event at Tokyo's Budokan gymnasium June 6, 2012. In a three-hour show broadcast live from Tokyo's hallowed Budokan, Oshima was selected as leader and face of the group, which has been recognized by Guinness as the world's biggest girl pop group. AKB48 is known for its perky routines and high "kawaii," or cuteness, quotient. Every year, fans vote to determine 64 of the most popular girls out of a 237-member pool who are then rotated in and out of four main troupes and several affiliated groups according to their popularity.
