The Flavor of Green Tea Over Rice (1952) on Netflix

Plot summary

Taeko and Mokichi Satake are a childless couple in Tokyo whose arranged marriage has run into difficulties. Taeko's friend Aya talks her into a deception: she tells Mokichi that her niece Setsuko is ill so she can leave town for a spa with friends. The plan nearly collapses when Setsuko arrives at the house, and Taeko names another friend, Takako, as the invalid instead. At the spa the women drink sake and watch the koi in the pond, likening a slow black one to Taeko's husband. Days later, at a baseball game, a public announcement calls Taeko home, where Setsuko waits with news that her parents mean to arrange a marriage for her. The family asks Taeko to serve as matchmaker for the girl.
