Miss Oyu (お遊さま, Oyū-sama) is a 1951 black-and-white Japanese drama film directed by Kenji Mizoguchi.
[1][2][3][4] It is based on the 1932 novella The Reed Cutter (Ashikari) by Jun'ichirō Tanizaki.
Tradition forbids that the widowed Oyū marries again, as she has to raise her son and future heir of her deceased husband's family, so Shinnosuke and Shizu marry as a means for him and Oyū being as close as possible.
Also, rumours about the true nature of the relationship between the three have started to spread, so Oyū insists on a geographical distance.
Shinnosuke, whose family has lost its fortune, leaves his child at the house of the remarried Oyū, asking her in a letter to raise it as her own.
