The music for the role-playing video game series Ni no Kuni, developed by Level-5 and published in Western regions by Bandai Namco Entertainment, is primarily composed by Joe Hisaishi and performed by the Tokyo Philharmonic Orchestra. Hisaishi, known for his previous work on Studio Ghibli films, agreed to work on the games after witnessing the development team's passion for the project. He aimed to make the music reflect the fantasy genre, creating a compatibility between the soundtracks and the game worlds.

Ni no Kuni  is a series of role-playing video games developed and published in Japan by Level-5; Bandai Namco publishes the games outside Japan. The first games in the series chiefly follow the young Oliver, and his journey to another world to save his mother and stop the beckoning evil. The sequel follows Evan Pettiwhisker Tildrum, a boy king who is usurped from his castle, and sets out to reclaim his kingdom. The games utilize several magic elements, allowing players to use magical abilities during gameplay, and follow groups of characters travelling the fantasy world to put an end to its threats.
