After Hiroshi is injured in a workplace accident, Torajiro gives Sakura the money he has saved and leaves to work as a traveling salesman once again. During his travels, Torajiro meets a father who shares a drink with him. In the morning, Torajiro is shocked to learn that the man has left his baby behind and a note asking Tora to take care of the child.
After Torajiro's latest attempt to find a bride goes awry, he starts traveling again and runs into Utako (last seen in Tora-san's Dear Old Home), now a widow.
In Part I we see the young would-be swordsman setting out to achieve greatness in war, achieving nothing because fighting on the losing side, & then beginning his long period of wandering & training, with the goal always in mind of his duel with Kojiro. Part II builds toward that great duel on Ganryu Island, with considerable focus on Musashi's planning & forethought as to how to gain an advantage.
Comedy of a phony doctor.
Torajiro becomes homesick during his travels after watching a television report about his hometown and meeting a young woman that reminds him of his sister Sakura. Meanwhile, a new tenant moves into Toraya restaurant.
