Door (1988, Banmei Takahashi)

Mom runs a cheesy household, where things are nice, and the family is always saying “oh how nice,” but as soon as she’s left alone she gets tormented by advertisers. She is Keiko Takahashi of Uzumaki, and her husband (Shiro Shimomoto of Serpent’s Path and Guard from the Underground) is the worst. One day she’s fed up with a pushy guy selling English lessons (Daijiro Tsutsumi of Sure Death 4) and slams his hand in the door, he starts aggressively stalking her. Movie is not great but almost worth it for a climactic long-take chase through the apartment filmed from overhead. She consistently does damage to the stalker, he never gets in any good hits, just keeps getting more and more injured until she does him in with a chainsaw.
