Love hotels feature in many Japanese films, including those, like Ryuichi Hiroki's "Kabukicho Love Hotel" and Izuru Kumasaka's "Asyl: Park and Love Hotel," that make such establishments a central focus. Typically guests drop their social masks within their walls, while employees get an up-close view of human nature, if not always human bodies, in the raw.
Takayuki Takuma's "Divine Justice" uses a room at a love hotel as a pressure cooker with sex, lies and a camcorder among the ingredients. As revelation follows revelation emotions erupt, from towering rage to craven fear. The nonstop plot twists are mostly played for laughs, though some of the humor edges over from the black to the disturbingly abusive.
Also, the back-and-forth between the characters stays shouty for so long it becomes numbing (or maybe that's just my geriatric synapses talking). Even so, veteran Hiroshi Mikami and the rest of the main cast deserve endurance prizes for surviving the film's marathon takes, the longest being 40 minutes. It's like watching jugglers add ball after ball but never dropping one. Not that the story makes much real world sense, but neither does the circus.
