Her modeling agency is Amuse. She was a regular model of the now defunct Candy magazine. She also appeared in the Winter 2002-2003 "Angel Blue" fashion catalog and was on the cover of the manga "Young Sunday" dated April 7, 2005.
She was a member of the 2004 edition of the Japanese modeling quartet named Nittelligenic. Prior to this, she did a few swimsuit layouts and continues to do them for magazines such as Sabra.
She has released six photobooks, and six idol DVDs. In order of release date, the photobook titles are: Ayaka no Natsu, Nicchoku, Summer Date, Moon Doll, and Cheeeeeez!♥. The DVDs are named, in order of release date, Figure A, Layer Game/Megami no Chu, Masaka, Moon Doll, 書を捨てよ、水着になろう! ("Throw away the book, probably become the swimwear!"), Dream Note, and Dream Note II.
She has acted in the following movies: "Odoru Daisousasen THE MOVIE 2" (her role in this film was relatively minor; she gets attacked by a vampire), "koibumi", "Master of Thunder", "A Perfect Day for Love Letters", "Drift" and "Drift 2" (later released as "Drift Deluxe Edition"), and "Boku wa Imouto ni Koi wo Suru" (which opened in Japan on January 20, 2007, and later in Europe under the English title "My Sister, My Love").
She also appeared in the reality show "Idol Michi" and made a commercial for Takara, "Popura 2," as well as an award-winning commercial for the soft drink Fanta.
Arguably, her best known job was as Minako Aino/Sailor V/Sailor Venus in the series Pretty Guardian Sailor Moon.
Since PGSM wrapped up, Ayaka was in the cast of a TV show called Dandori Musume ("Appointment Girls"). Her role in Dandori Musume is more comic than tragic, in contrast to her PGSM role. Her latest TV shows are dramas called "Girl's Life" and "Bambino". CD Japan lists a show called Uranaishi Tenjin ("Fortune Teller's Display") with her in the cast.
In October 2007, she acted in a play called "Unlucky Days".
