A curious film from Kurosawa, given what came later, this is a nationalist film about a group of young women who are working at an optical instruments factory who are given the task to greatly increase productivity for the good of the country and the war effort. It shows them rarely at play, mostly very focused at work. Takako Irie plays the dorm mother, a somewhat sympathetic character. This film is more inherently Japanese than most of Kurosawa's later work, its almost a propaganda film. However, there is also some heart in the characters, and that is what makes it a recommended film. You sense the young ladies anguish over being sick and having family difficulties, making them unable to work. So, not essential viewing but still watchable and Kurosawa fans should check it out.
