Composer Joe Hisaishi of Studio Ghibli fame commented on the appeal of the film and the challenges on working on its soundtrack. He described the story as both unpredictable and philosophical. He thought the soundtrack was quite challenging as it permeated the entire film, but with a minimal music style. He added that the film inspires the viewer's imagination with the faint whiff of the universe's memories and the effervescence of life.
