One should first read The Makioka Sisters by Junichiro Tanizaki to better understand this film. It is a very great novel about the life of four middle-class sisters in Osaka, Japan in the 1930's. The book describes in great detail the many subtleties of life in Japan which a Westerner can miss understanding in the film. The film rather closely follows the book and is very beautifully photographed.
