She was selected to participate on compilation CD produced every year by vocal students. She started vocal lessons, learns lyrics and composition.[1] After graduating, Ishii took part in an audition.

In December 2002, after the release of Shinsaku Douyou Pops 1, Ishii left Hello! Project to explore her own music. She said in a 2009-interview that "As an idol in Hello! Project, I did some concerts on big stages, I also spent time on television programs. These experiences were very pleasant. However, when I spent all these days as an idol, a thought came to my heart; "I want to convey my words in my songs with everyone and directly" and it became stronger every day. When I discussed my desire to end my career as an idol, my family, my friends and of course the music industry teams of course objected to this idea. I was really sorry to my fans and the team who supported my career and I was keeping this to myself about this idea. I was imagining my future. Two years after what did I want to be? Ten years after what did I want to be? The answer to that  was very clear to me. I have only one life, I wanted to be myself and I still continue to question myself today."[4]


In May 2003, Ishii held her first live performance, playing original songs written by herself. She also released the self-produced single "Kotoshima".


In 2006, Ishii starred in the horror movie "zoku", directed by Kobuta Shouji. It was released on November 25 at Shibuya Uplink. She also released her major debut single Ao in August, which was featured in the movie.

Ishii said in a 2009-interview that she would release a mini album in spring 2010. She also said: "Through this release, I will wish to expand my activities across the country and around the world.  And as the next stage of my musical career, I'd like to produce artists one day. I learned many wonderful things from artists that I respect and I would like to convey these things to the next generation."

In 2010, Ishii released her major debut album Aoi Kuma, holding a live performance called Aoi Kuma no Daiippo (あおいくまの第一歩).
