In pre-war Japan, two members of a large yakuza syndicate instigate a turf war that embroils the highest echelons of Tokyo's underworld.

Junko pretends to be a yakuza and gets more than he bargained for when he is tasked with avenging the murder of a fellow gang member. If he turns the task down, he will face the consequences for betrayal.

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.

When his travels bring him to Osaka, Tora-san falls in love with a local geisha. He helps her to track down her estranged brother, and informs his family that he plans to marry her. His plans are foiled when the geisha informs Tora-san that she is engaged.

Tora-san's nephew Mitsuo is exchanging letters with Izumi, a former classmate whose parents divorced and took her out of Tokyo.

Tora-san returns to his family home to learn that his brother-in-law cannot go to Mitsuo's (Tora-san's nephew) athletic event. Tora-san volunteers to take his place, but gets into an argument with his brother-in-law's boss and returns to the road. He meets a young woman in Niigata who, unbeknownst to him, is a popular enka singer.

Tora-san visits brother-in-law Hiroshi's hometown to attend a memorial service for his late father. When the local temple priest becomes intoxicated, Tora-san wearing the priest's robe delivers the memorial speech, much to his family's surprise. Thinking he's found his true calling, Tora-san decides to join the order, and falls for the priest's divorced daughter.

In Shibamata, Tokyo, Tora-san's family prepares for a wedding. Meanwhile, the traveling Tora-san meets an old acqaintance in Iwate Province. Tora-san refuses to drink with him, afraid that the acquaintance, now settled and married, will again become attracted to Tora-san's wandering existence. Tora-san becomes attracted to a female barber, but must break off their relationship so that she too can live a secure life. She instead gets into an abusive relationship with a motorcyclist.

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 spends several days at the home of a hard-working salaryman ("salaried worker"), who abruptly disappears. When the man's wife asks Tora-san to help find him, he falls in love with her, and secretly hopes the husband will not be found.
