Iron Brothers.

It's been a long time since the war. Since we haven't been at war with America yet, there is a line in the movie that asks, "How do you say "dried fish" in English?" Brothers who work at a factory that handles iron in Tokyo. After losing his parents, his older brother (Takada Minoru) sends his younger brother (Ito Kaoru) to night school, and the brothers help each other survive. The older brother wants his younger brother to study and attend a higher school (university?). A mysterious woman (Sachiko Chiba) moves into the apartment where the two live. The landlady of the apartment is busy gossiping about her and who she is.
