I'm working steadily through Mizoguchi, and it's clear he makes films about how men don't make life easy for women, This film is no exception. I thought there were two main strands: Akiyama's professorial assertion of the acceptability of adultery and Ono's single-minded world of business. Akiyama thinks it's all right to go off with Ono's wife who feels ignored by her husband, but he's furious with his own wife, Michiko, who, as a samurai keen to retain her family's reputation, has had to spend a (sexless) night in a hotel with her cousin, Tsutomo, owing to a rainstorm. It is clear the cousins love each other, but Michiko is able to resist her temptations, while Akiyama isn't. Furthermore, Akiyama attempts to steal and cash in the deeds of Michiko's property. At the same time, Ono, who is also Michiko's brother, tries to borrow money from her for his failing business by asking her to mortage her property. By the end of the film, the only one to have saved face is the honourable Michiko.
I enjoyed the film, but found it a bit meodramatic. Nevertheless, the working-out of the inevitable tragedy was compelling enough to keep me watching, as was the acting all round.
