Who composed the Kingdom Hearts music?

Yoko Shimomura (born 1967, Hyōgo) graduated from Osaka College of Music in 1988 and spent five years at Capcom, where her credits include Final Fight and, with Isao Abe, the soundtrack of Street Fighter II. She moved to Square in 1993 and built the other half of her reputation there: Live A Live, Super Mario RPG, Parasite Eve, and Legend of Mana, the score she has called her fullest self-expression. She left Square in 2002 to work freelance, the same year her largest assignment arrived.

For Kingdom Hearts she is the series’ composer in the singular sense: “Dearly Beloved,” the piano theme that plays over every title screen in the saga, was the first piece she composed for the first game, written while she played an early demo. She has named it her favorite among her own compositions, and has described the Kingdom Hearts scores as her magnum opus. The arrangement changes with every installment, swing, strings, full orchestra, so that the melody functions as the series’ memory of itself.

The later games share the load without changing the signature: Birth by Sleep and Kingdom Hearts III credit Shimomura alongside Tsuyoshi Sekito and Takeharu Ishimoto, while she remained lead composer of the series and, in parallel, scored Final Fantasy XV (2016) and Nintendo’s Mario & Luigi games. Her Kingdom Hearts music has toured the world as dedicated orchestral concerts, including the World of Tres tour at which Re Mind was announced. In 2025 she received the BAFTA Fellowship, British film and games’ highest honor, an award that cited a career running from Street Fighter II to the theme every Kingdom Hearts player can hum.
