image, idols are generally not regarded as authentic artists. Likewise, many young Japanese artists pursuing careers in acting or music reject the idol label in their bid to be seen as professionals. Music from idol singers is generally categorized under J-pop, though talent agencies may label them under the sub-genre "idol pop" for further distinction. Many idol singers find success as groups rather than individually. Within each idol group, the members are sometimes given distinct roles. One example of a role is the center, who occupies the center position in the group's choreography and thus receives the most focus. Another example is the leader, usually relegated to the oldest or most experienced member in the group, who acts as an intermediary for the members and the staff.

Since then, other groups have used stylized school uniforms as costumes, such as AKB48's sister groups, Sakura Gakuin, and Sakurazaka46, with some modifications to suit the groups' image and choreography. In 2017, Nihon Tarento Meikan noted that stylized school uniforms being used as costumes gained popularity through AKB48 due to their unique designs, the short skirts, and the neatness of the uniform. The uniforms found popularity with
