The album was released on 25 March 1999 as a 12cm CD and fully produced by the legendary Tetsuya Komuro or TK, and he took part in every aspect of it, even in lyric writing. The album had pretty strong sales as it sold nearly 2 million copies, achieving a simply amazing success in her country. The album was re-released on MiniDisc on 28 April 1999.

After a legal dispute between Suzuki and her manager in September 2000, Sony put the album out of print along with all other Ami Suzuki singles and albums released up to that point, and she was blacklisted from the J-pop music scene. However, after she re-debuted under Avex Trax in 2005, the album was re-released later that same year as part of her Bazooka 17 box set. It was later re-released in a remastered version on the Blu-spec 2 format on 11 September 2013 simultaneously with her second album Infinity Eighteen Vol. 1.

The title of the album, SA, comes from Suzuki Ami, the name of the artist.

The album charted for 33 weeks on the Oricon charts.
