Since 2010 in Japan, the AKB48, one of the most famous female groups of J-pop, organizes tournaments of shifumi (stone-leaf-scissors) for its fans. This year, the stakes were high because the annual tournament, which took place last October, made it possible to select a new singer. AKB48 is composed of several subgroups. Each subgroup must regularly change the singer star, which will be at the center of the choreographies and the shows. The winner is Tanabe Miku.
