After ℃-ute disbanded in June of 2017, Okai had been appearing on various TV programs as a talent. However, last April, she decided to take a break from her activities. Not even a month ago, she announced that her contract with JP Room had ended and had retired from showbiz.
On Twitter, Okai wrote, "This is Okai Chisato! I opened a Twitter account as Okaike!! Also, I have launched a fan club for Okaike. As Japan currently faces a difficult situation, I wanted to cheer up everyone and bring a smile upon everyone's faces in many different ways." She continued, "My new start came a little earlier than expected so some might disapprove of it, but I decided to go with this timing."
