Sakura Gakuin (さくら学院) are an idol group under the Amuse agency whose music and activities are based on the Japanese school system. Just like in Japanese schools, the members of Sakura Gakuin wear a special uniform. The Japanese school year ends at the end of March, and this is when Sakura Gakuin release their albums. Singles are released at various times throughout the year. Also just like Japanese schools, Sakura Gakuin have “school clubs” with a variety of themes. When a member of Sakura Gakuin graduates from ninth grade in real life, she also graduates from the group.
