In 2012, Team Okai was formed by Okai Chisato. The original line-up consisted of Okai, S/mileage 2nd generation members Nakanishi Kana, Takeuchi Akari, Katsuta Rina and Tamura Meimi, and Hello Pro Kenshuusei members Kaneko Rie, Miyamoto Karin (now part of Juice=Juice), Takagi Sayuki (now part of Juice=Juice), Tanabe Nanami and Yoshihashi Kurumi.
On October 19, 2012, the unit debuted on ℃-ute's YouTube channel, releasing a dance cover video of Wakuteka Take a chance. In early 2013, Hello Pro Kenshuusei member Murota Mizuki (now part of S/mileage) was added to the unit to cover Oda Sakura.
On April 13, the unit released a dance cover video for "Brainstorming" on ℃-ute's YouTube channel.
Due to some members leaving Hello! Project and the creation of the rival group Hello! Project Station Dance Club, Okai stated in an interview with Dwango in July 2014 that she was looking for new members.
On June 22, the unit was revived with new members at ℃-ute Okai Chisato Birthday Event 2016, where they performed a dance cover of "Brainstorming" and sang "Kanojo ni Naritai!!!". After this, the unit became inactive once more, and effectively disbanded.
On May 11, the unit briefly reunited when Okai Chisato performed on Fuji TV's "Monomane Kouhaku Uta Gassen" with four Team Okai back-up dancers.
