Ai Carina Uemura (植村 愛 カリーナ, Uemura Ai Karīna; born November 2, 1981), known mononymously as Ai (Japanese pronunciation: ai, stylized as AI or A.I. ), is a Japanese-American singer, songwriter and rapper. Known in Japan as the "Queen of Hip-hop Soul", her 2005 single "Story" went on to become her breakthrough release, becoming one of the best-selling multi-format singles in Japan with over 5 million units sold. A multi-million record selling artist, Ai has released thirteen studio albums and has received various accolades, including two Billboard Japan Music Awards and three Space Shower Music Video Awards.
Born in Los Angeles, Ai moved to Kagoshima during her early childhood. Motivated to become a singer, she returned to Los Angeles during her adolescence, attending the Los Angeles County High School for the Arts. While in Los Angeles, she performed as part of a gospel choir at a Mary J. Blige concert and appeared as a backup dancer in Janet Jackson's music video, "Go Deep". She briefly joined the Asian girl group SX4 in 1999 until she graduated from high school. After being discovered by BMG in 2000, Ai relocated to Japan and released her debut album, My Name is Ai (2001), to very little commercial success.
Signing to Def Jam Japan in 2002, Ai became the first woman signed to the label. She released two studio albums under the label, Original Ai (2003) and 2004 Ai (2004).
