Ishida entered the entertainment industry after winning a contest to become an anime song singer. She made her debut in 1993 with the song Otome no Policy ("Maiden's Policy"), ending theme for the Sailor Moon R anime. At the time her name was written as 石田よう子, but it was later changed to 石田陽子. In 2000, she changed it again to 石田燿子, which she uses to this day.
Apart from anime songs, she has also sung children's songs.
