Ai Carina Uemura was born in Los Angeles, California on November 2, 1981. Her father, Hisashi Uemura, is a former construction business owner and her mother, Barbara Uemura (née Endo) is a former real estate agent. She has one younger sister, Sachi Ueyama (née Uemura), and is of Italian and Native Okinawan descent.
When Ai was four, her family moved to Japan as her father found work at a construction business in Kagoshima. Her family had intentions of returning to Los Angeles within a year however decided to stay in Japan as her father took over business operations of the construction company. During her early childhood, Ai struggled to communicate with her family and peers at school, often blending English and Japanese phrases. Her mother only spoke English at the time while her father, who fluently spoke Japanese, was often away from home due to work.
During her early adolescence, Ai was motivated to become a singer after she sang at her cousin's wedding, having many people ask her if she wanted to be a professional singer, and hearing a gospel performance at the First African Methodist Episcopal Church of Los Angeles in 1993. After graduating from junior high school in Japan, Ai returned to Los Angeles for high school, initially enrolling at Glendale High School, however found high school difficult due to never formally studying English. After a successful audition process, Ai enrolled at the Los Angeles County High School for the Arts, majoring in ballet. She became a member of the school's gospel choir.

### 2000–2004: Relocation to Japan

While on a summer holiday in Kagoshima, Ai performed Monica's "For You I Will" on a local radio station, which led to her being scouted by BMG. She decided to take the offer, and after leaving SX4 and graduating from high school in June 2000, moved to Tokyo and debuted as a musician later in 2000.
Ai debuted under BMG Japan sublabel RCA Records with the single "Cry, Just Cry" in November 2000. Two additional singles were released, "U Can Do" and "Shining Star".

In 2004, she won the Space Shower Music Video Awards' award for Best R&B Video, with her song "Thank U".
