Reina Tanaka is a Japanese singer, actress, and voice actress born on November 11, 1989, in Fukuoka Prefecture, Japan. She first rose to prominence as a performer in the entertainment industry before establishing her career as a voice actress.

Tanaka's career in the public eye began in music when she became a member of the popular J-pop group Morning Musume in January 2003 as part of the sixth generation. She remained a main vocalist with the group until her graduation in May 2013. Following her departure from Morning Musume, she formed and led the all-female rock band LoVendoЯ, with whom she released music until the group entered an indefinite hiatus in June 2019.
