What is the name of the main theme song of the Gran Turismo series?

The main theme song of the Gran Turismo series is “Moon Over the Castle.”

The song was composed and performed by Japanese guitarist Masahiro Andoh, whose work became closely associated with the identity of Gran Turismo. It first appeared with the original game and has been used in various forms across the franchise, especially in Japanese releases and promotional material.

“Moon Over the Castle” is not simply a generic racing-game soundtrack cue. Its driving guitar-led arrangement gives the series a dramatic, aspirational tone that matches Gran Turismo’s emphasis on automotive culture, precision, and the dream of mastering real cars on virtual circuits.

Players sometimes confuse the title with a localized opening song or with individual tracks from the games’ broader licensed soundtracks. Regional versions have included different music, and later entries have featured many artists, but “Moon Over the Castle” remains the franchise’s signature theme. The title is also commonly written with “Over” capitalized, as in the stored answer.
