Japan Akb48 Girl Idol Group Official Website Akb48 is a large female idol group in Japan, with Yasushi Akimoto as the chief producer, and has won the Japanese Golden Record Award.

The group Akb48 was founded in 2005. Its name is taken from Akihabara (Akiba) in Tokyo. The number of members has increased and decreased several times, and now there are 139 members, divided into 5 sub-groups and graduate teams, mainly for grouping in theater performances on a rotating basis. It is now also certified by Guinness World Records as the world's largest pop group.

According to the idea of Yasushi Akimoto, the original intention of the establishment of AKB48 was to make the concept of "Idol" (Idol), from a distant existence that could only be reached through the media, become close to the fans, so that they can see their growth process, and their relationship with them. The Idol Project is a project that allows fans to see their growth process and grow with them. In recent years, with the growing popularity of AKB48, more and more of its members have gone into other fields of artistic endeavor outside of their singing careers.

The songs used in the recording and public performances are all original songs written by Yasushi Akimoto, and by November 2011, over 400 original songs have been released. The lyrics of all songs are written by chief producer Yasushi Akimoto, and various composers are invited to participate in the composition. The stage manager and choreographer is mainly responsible for the choreography of the Hayate family and other groups such as Natsu Mayumi (later on, Anna Makino and others will be in charge).

AKB48 has a large number of members, is the Guinness World Records certified the world's largest number of members of popular music groups. Due to its large number of establishment characteristics, in the event of performances or the launch of new works, usually only selected some of the members, plus AKB48's works and often have members of other sister groups to participate, so the membership list changes a lot. In order to facilitate sorting and reference, the "48 Group" formed by AKB48 and its sister groups has developed a principle regarding the sorting of the list, which does not determine the order according to the reputation or qualifications of the members, but rather categorizes and sorts the members who participate in specific activities or productions according to the team they belong to, and then sorts the members who belong to the same team according to their names. The members of the same team are then sorted according to the Japanese fifty-syllables of their names, which is called the "attendance number" of the members.
