Mika Nakashima x Hyde is a Japanese collaboration credit pairing Mika Nakashima with Hyde. Nakashima, born on February 19, 1983, in Hioki, Japan, is a Japanese vocalist associated with ballad, pop, and J-pop, and she is signed to Sony Music Entertainment Japan. The collaboration sits at the intersection of vocal-led pop and dramatic balladry, which fits both artists' broader profiles.
Nakashima debuted in 2001 with "STARS," the theme song for Fuji TV's drama Kizudarake no Love Song. Early singles including "CRESCENT MOON," "ONE SURVIVE," "HELPLESS RAIN," and "WILL" helped establish her as a major J-pop vocalist with a strong theme-song presence. Her career also reached film audiences through the NANA franchise, most notably with "Hitoiro" for NANA 2 under the name NANA starring MIKA NAKASHIMA and the album THE END. She has also recorded cover versions of "Amazing Grace," "The Rose," and "What a Wonderful World," while Hyde's participation adds another layer of cross-scene appeal.
