In 2004, Berryz Kobo was created with the intention of rotating all of the members of Hello! Project Kids to make time for school, but the idea was later scrapped, and the remaining girls who were not chosen were re-branded under the name Cute on June 11, 2005.
In September 2007, Okai was added to a new unit called Athena & Robikerottsu with Risa Niigaki, Aika Mitsui, and Saki Nakajima.

Her first solo live event, "Chisato Okai (Cute) Solo Live 2011 Vol. 1: Kaisha de Odotte Mita!!" was held on January 25, 2011, at Pacific Heaven. A CD containing Okai's cover of Miki Fujimoto's "Romantic Ukare Mode", with "Love Namidairo" as the coupling track, was sold exclusively at the venue of her second solo live, but was also released digitally as part of Hello! Project's Hello Cover series.
In August 2016, Cute announced plans to disband in June 2017. Okai expressed interest in becoming a television personality on variety shows following disbandment.
She retired from the entertainment world on April 30, 2020.
Okia announced in April 2019 that she would be taking time off from all entertainment activities. She noted that she had been in entertainment for 17 years, and sought to experience life from outside of the industry.
