The quiet life of a mother and her young son living on a farm in Hokkaido is changed by the arrival of a man who ignites flames of romance in the heart of the mother and shows her boy the importance of grit and kindness, but then he leaves with the autumn wind.

A playboy-gambler friend of Tora-san’s dies and, abandoned by his mother, his little boy suddenly turns up in Shibamata. Searching for the boy’s mother, Tora-san meets a cosmetics saleslady and the three become a surrogate family, with Tora-san as “daddy”.

Taking the Chilean coup as an example, a group of young officers plan to overthrow the Japanese government on V-J Day. They aim to abolish the post-war constitution, restore the national army and revive the traditional spirit of Japan. As the conspiracy is exposed, the coup squadrons are wiped out one by one. The remaining squadron takes over a night train bound for Tokyo.

Tora-san returns to his family's home to attend an elementary school class reunion. After he embarrasses himself by getting drunk and insulting all his ex-classmates, he resumes his travels. In Kyushu he meets an outspoken 18-year-old girl who becomes enamored of Tora-san and follows him around. One of Tora-san's old friends is terminally ill and makes Tora-san promise him to marry his wife once he is gone.

When his travels take him to rural Hokkaido, Tora-san helps a cantankerous old veterinarian (Mifune) in his relationships with his estranged daughter, and a woman in whom he is secretly interested.

Tora-san's opinions about Americans get challenged when another wandering peddler Michael Jordan stops by Shibamata.

In his travels through Japan, Tora-san meets and falls in love with a female doctor, however he is afraid of committing to a relationship.
