AKB48 (pronounced A.K.B.

As of August 2014, the group has expanded to include 140 members 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.Akimoto has expanded the AKB48 concept to several sister groups in Japan, China and Indonesia.
