Who composed Ultimate's main theme, Lifelight?

Hideki Sakamoto composed Ultimate's main theme, “Lifelight.”

“Lifelight” is the central vocal theme of Super Smash Bros. Ultimate. Hideki Sakamoto wrote the music, while the English and Japanese versions feature vocals by musician and singer-songwriter Samantha Kelly. The song appears prominently in the game's opening presentation and is closely associated with the World of Light adventure.

The answer is sometimes muddled because Ultimate's soundtrack contains hundreds of arrangements and contributions from many famous game composers. Yoko Shimomura and Koji Kondo are both prominent composers connected with Nintendo and other major game series, while Nobuo Uematsu is strongly associated with Final Fantasy. None of them composed Ultimate's main theme.

Ultimate's music reflects the series' crossover identity: alongside original material such as “Lifelight,” it includes arrangements drawn from Nintendo franchises and third-party properties. Hideki Sakamoto's credit is specifically for the main theme, not for every musical track in the game. Ultimate was released for Nintendo Switch in 2018 and reunited the development partnership behind Smash 4.
