In Nagasaki, Tora-san and an acquaintance help an old woman who has fallen and injured herself. She invites them to her home where the three share a night of eating and drinking. The old woman's health deteriorates and she dies. At her funeral, Tora-san falls in love with the old woman's daughter, but winds up acting as a go-between for her and a young law student.
Tora-san gets into an argument with his uncle and sets out on the road again. In Kyushu he meets a young woman named Keiko and the shy zoologist Saburō, and attempts to play matchmaker between the two when they all return to Tokyo.
During his travels, Tora-san gets drunk with an old man in Kyoto. Though Tora-san never fully comprehends his importance, the old man is a Living National Treasure ceramist. At his home, Tora-san makes a good impression on the old man's maid, who apparently falls in love with Tora-san.
