AKB48 Members

AKB48 Logo

The 1st to 3rd Generation are known as the Original Teams (1st Gen: Team A, 2nd Gen: Team K, 3rd Gen: Team B).

As more auditions were held later on, the successful candidates would take part of an in-training team of members. The trainees would work as "under members" that substituted for the official members in various activities, especially the theater performances. When any of the official members would graduate, one of the in-training members would be promoted to fill the space.

This group of trainees was called AKB48 SEED. The term was was dropped later on, and changed to Kenkyuusei (Research Students). After more generations were created, the Kenkyuuseis started to perform by their own stages in the theater. In 2009 Team Kenkyuusei was created, and the Kenkyuusei Selection was held for the first time. Since then, the Kenkyuuseis have even been part of senbatsu. In 2012, with the Tokyo Dome Team Shuffle, the Kenkyuuseis stopped replacing members on stage performances, just performing on their own Kenkyuusei Stage.

Currently, with exception of the 8th generation, all the generations have at least one member in the group. The members after the 9th generation are usually called the new generation members. Recently this term been used to describe the members after the 12th generation instead.

AKB48 had a total of 186 original members during all their 15 generations. As of May 2015, AKB48 has 129 members and 13 Kennin (including Team 8 Kennin).
