The story has basically the same structure and outcome as Late Spring. But it's very different in the way the ending is developed. Ozu focusses much more on the father and how he realizes the tragedy in the whole story. It becomes clear, that he revels in memories of happier days and will never be able to escape them. Like in the other film the ending reveals a deep insight into the sorrow of the characters.
Great use of colors and very interesting framing. Loads of hallways, doorways and other interior structures frame pretty much every picture and are very carefully arranged. (Study this for interior shots)
