AAA (pronounced as "Triple A") is short for "ATTACK ALL AROUND". AAA has two lead male vocalists (Nishijima Takahiro, Urata Naoya), one lead female vocalist (Uno Misako), one rapper (Mitsuhiro Hidaka), and has all seven members as dancers (other members include Sueyoshi Shuta, Atae Shinjiro and Ito Chiaki). AAA is meant to appeal to music listeners of all sorts.

The Avex Trax group debuted in September 2005 with the Japanese theme song (BLOOD on FIRE) to the Initial D Live-Action Movie, which reached #9 on the Oricon Singles Charts. In the same year, they won The 47th Japan Record Award for Best new artist.

AAA has since released 3 albums (ATTACK, ALL, CCC), 2 mini-albums (ALL/2, alohAAA), 1 Remix Album (REMIX ATTACK), 5 DVDs and 17 singles, with Natsumono as their latest.

They are set to release their 4th Album, "AROUND" along with their new single "Red Soul" come September 2007.

As of 11th June 2007, Goto Yukari has left AAA due to her continuing health problem, leaving AAA with 7 members. She has since gone on to pursue a career in advertising.
