The Crazy Family (1984)

The Kobayashi family finally are able to move out of their tiny, cramped Tokyo apartment to the suburban house of their dreams. But things are not as perfect as they seem: the house is infested by termites and the family starts going crazy. As the Kobayashi's house begins to crumble, so does the sanity of its inhabitants. Father Katsuhiko takes it upon himself to keep them from the asylum… at any cost.
