In 2012, Shin-ichiro Ikebe was announced to write the film's score. However, in 2013, Joe Hisaishi replaced Ikebe as the composer. This would be the only time Hisaishi scored a film directed by Isao Takahata. The theme song "When I Remember This Life" was written and performed by Nikaido Kazumi. The music from the film's original soundtrack was released on 20 November 2013.
