At one time, Aoki was part of a five-person comedy group called Onsen Konnyaku Acrobat Show.
Aoki's popularity grew around the fall of 2003 as she started appearing in Fuji TV Network's Warau Inu No Taiyo (The Sun of the Laughing Dog), NepLeague and TV Asahi's Out of Order, thanks to the strong promotion by her agency.
She also grew popular by performing comedy sketches on Enta no Kamisama (The God of Entertainment).
Aoki was the first person to host the FNS ALL STARS: 25 HRS TELEVISION as an official Fuji TV Announcer (which was designated just for this occasion) and read the last notes.
[citation needed] On October 25, 2007, Aoki published an "I Novel" (auto-biography) titled Because I'm 34, I'm feeling happy (ISBN 978-4334975272).
