Sound is used in this film like a mantra. All the bells and repeating motifs make me cry on their own. This film deserves a lot more respect than it's given and is so different from the rest of koreeda's films, it was a starting point for me.
The shower scene is one of the most effective uses of sound design for me. Sound art is used throughout this film in a very brave way that hasnt really been repeated and for that alone this film earns top marks
