Sakura Gakuin
Sakura Gakuin was created around April 2010 by the talent agency Amuse. Members of the group often blog in a class journal by posting notes handwritten on loose leaf paper. In August, the group participated in the first Tokyo Idol Festival (TIF). In October, the group formed the baton-twirling sub-unit Twinklestars, with seven members; in November, the group released its first single "Dear Mr. Socrates", which was sold only at live venues. Sakura Gakuin held its first solo event on November 28, 2010.
