The story of Sanshiro, a strong stubborn youth, who travels into the city in order to learn Jujutsu. However, upon his arrival he discovers a new form of self-defence: Judo. The main character is based on Shiro Saigo, a legendary judoka.

In this government-suggested sequel, Sugata again grows as a judo master, and demonstrates his (and by extension, all Japanese) superiority to the foreign warrior.
