Yua Aida was born in Aichi Prefecture, Japan, on 12 August 1984. Aida was an active girl and involved in many sporting activities during primary and middle school. Tennis was her strongest sport throughout middle school. In high school, she changed her focus from sports to art, an interest she attributes to her mother. Aida reports that exposure to nude models while oil painting helped her to be more comfortable when she began her AV career. After her graduation from high school, Aida began working at a part-time job. At this time she was scouted by an AV talent agency while shopping in Tokyo's Shinjuku neighborhood. Aida says that she was not impressed with the talent scout, but when she met the company president, she thought, "This guy is really great. I’m gonna work here!"
