In 2004, Hello! Project held a nationwide audition titled "Hello Pro Egg Audition 2004". Out of over 10,000 applicants, 31 girls were successful.^[2] Six out of the seven members were originally part of the "egg" generation, while Sato Ayano joined the trainee group in 2009.^[3] During the last egg concert of 2010, Hello! Project announced a change in their trainee group. As part of this change, many older members completed their training, but were not added to the major groups within Hello! Project.^[4] Saho Akari was the last to complete her training.^[5] Up Up Girls originally consisted of six girls, later growing to seven with the addition of Saho Akari.^[6] Their first event was held on May 1, 2011.^[7]

YU-M is their primary management while Up-Front Create is a producer of their releases.^[9]

2016 to 2017

Under YU-M, the group reached their dream of performing at Nippon Budokan. The company was able to afford the rental cost, but "ran out" of money for outfits and decorations.^[11] This resulted in the crowdfunding of over 12,000,000 JYP. The crowdfunding was successful, but they did not reach their goal of selling out the venue and only filled a little over 4000 of Budokan's 14,000+ capacity.^[12]

At this Budokan concert, they announced their search for girls who would become either a sister group, rival group, or full members.^[13] The auditions began on November 8, 2016. In February the four successful applicants from the audition were announced.^[14] With a late addition to the group, these five girls formed Up Up Girls (2), pronounced Kakko Niki.^[15] They are a sister group to Up Up Girls (Kakko Kari). From May 29 to June 19, 2017, auditions for Up Up Girls (Pro-Wrestler) were held.^[16] From these auditions, four successful applicants formed the newest addition to the Up Up Girls lineup.
