The soundtrack for the film revolves around three songs by The Blue Hearts, who were apparently a big deal in the ‘80’s in Japan. By the end of the film we were left wondering what significance the rat has in Japan—one lyric that is repeated throughout the movie n is “Like the rat, I want to be beautiful”.

We walked away from the film convinced that all Japanese school girls have knock-knees and that teen angst is alive and well in Japan, albeit in a far more adorable form than here.
