Background: AKB48 (pronounced A.K.B. Forty-eight) are a Japanese idol girl group named after the Akihabara (Akiba for short) area in Tokyo, where the group's theater is located. The group has expanded since then to include over 130 members as of December 2015, aged from their early teens to their mid-20s. AKB48's producer, Yasushi Akimoto, wanted to form a girl group with its own theater (unlike pop groups performing occasional concerts and seen on television) and performing daily so fans could always see them live. This "idols you can meet" concept includes teams which can rotate performances and perform simultaneously at several events and "handshake" events, where fans can meet group members.

According to an early press release the group was intended to have 16 members on each of three teams, for a total membership of 48; but its membership has varied over time, and has exceeded 120 people. New members are called trainees (Yan Jiu Sheng , kenkyusei) who are understudies for the group, performing occasionally in the theater as a team. In addition to their performances with the group, members are promoted by the Japanese mass media. AKB48 regularly hosts events, where fans can interact with the members, such as taking pictures or shaking hands with the members.  The group members' ages range from their early teens to over 20, and they are selected from regular auditions. Members are not allowed to date, and must be well-behaved; any violation of t
