Phil Newton’s review published on Letterboxd:
Takafumi (Nao Ohmori) is a quiet father with a secret S&M fetish. Joining a bondage club, he's informed that membership will last for a year and he'll never know when the various dominatrixes will appear to humiliate him. From Hitoshi Matsumoto - director of the equally off-the-wall Symbol and Big Man Japan - R100 (the title is a nod at the age rating) the film is not explicit, focussing firmly on the comedy of the situations. It is laugh out loud funny too, especially in its self-deconstructing moments.
