AKB48 is a Japanese idol musical girl group named after the Akihabara area in Tokyo, where the group's theater is located. AKB48 has sold more records than any other female musical act in Japanese history. AKB48's producer, Yasushi Akimoto, wanted to form a girl group with its own theater 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 girl groups within Japan, and internationally in Mainland China, Indonesia, Thailand, Taiwan, and Philippines.
