Sakura Gakuin
Sakura Gakuin is a Japanese idol girl group formed in 2010 by the Amuse talent agency. The group's membership falls within the age range of Japanese compulsory education, typically containing between 10 and 12 members at a time who fall between the ages of 10 and 15. With the theme of school life and extracurricular club activities, when the academic year ends at the end of March, the group releases an annual studio album, new members "transfer in" to the group, and others who finish compulsory education "graduate", or leave.
Members of the group also belong to one or more of its sub-units, which are modeled after school extracurricular clubs. Each club performs with its own theme and musical genre, and their music may be included in the main group's albums or released as a separate single.
Concept
The group functions as a "unit limited to the growing period", typically containing between 10 and 12 members at a time who fall between the ages of 10 and 15, and therefore are between fifth and ninth grade. The group is themed around the idea of school life and extracurricular activities, featuring a "principal", Mitsuru Kuramoto, "teacher" Hayashi Mori, and sub-units designated as "clubs". The group releases an album annually in mid-March, the month marking the end of the academic year, leading to a concert at the end of the month in which the most senior members "graduate", or leave, in accordance with having finished their compulsory education. Each May, new members from lower grades "transfer in" to the group.History

Members
Sakura Gakuin employs a line-up changing system in which older members leave the group and new members join each year. Since the group's theme is that of an elementary and junior high school, when a member graduates from junior high, specifically her third year, she leaves Sakura Gakuin as well, during a ceremony the group holds around the end of the Japanese school year in which these members "graduate"., the group consists of the following twelve members.
