Sayuri Sugawara (菅原紗由理, Sugawara Sayuri?) is a Japanese pop star, known to the Final Fantasy community as the artist of "Kimi ga Irukara", the theme song for the Japanese version of Final Fantasy XIII.
On September 3rd, 2009, it was announced at the Final Fantasy XIII premiere in Japan that Sugawara will perform Final Fantasy XIII's theme and insert song. Seeing as the song was composed by Masashi Hamauzu, Sugawara performed the song at the premiere with a live orchestral accompaniment, the world's first preview of the theme song.
Her single for Final Fantasy XIII includes "Kimi ga Irukara", as well as "Eternal Love". "Kimi ga Irukara" was originally going to be included for the Western version of the game, but due to translating difficulties, "My Hands" by Leona Lewis was used instead. "Eternal Love" is replaced with "Serah's Theme". Sayuri Sugawara was not referenced at all in the Western version.
