In the 1880s, a martial arts student continues his quest to become a judo master, from that discipline's founder. Eventually, he learns enough to demonstrate his skill in a boxing match between American and Japanese fighters- at the end of the movie. The whole movie is actually about the rivalry between karate and judo martial artists, and Sanshiro's struggle to do whats right. On one side there is the morally right thing to do, and on the other the rules in the dojo. Eventually he decides to break literally all the rules, leave the dojo, fight the American boxer and, also, the karate masters. He wins both fights and at the end of the movie smiles while washing his face, finally able to sleep and finally be happy
In his review of the original Sanshiro Sugata for Bright Lights Film Journal, Brian Libby noted that the film is "less propaganda-oriented" than its sequel. In the original film, "fighting is but a vehicle for a larger spiritual quest" whereas the sequel "promotes Japanese judo's superiority to Western boxing", setting a different tone. Christian Blauvelt, writing a review for Slant Magazine, agreed that the film is somewhat tainted by noticeable propaganda. Sanshiro's victory against the American boxer "is taken as a sign of Japanese physical, moral, and spiritual superiority". He also noted that "Sanshiro comes to the aid of defenseless Japanese who are being beaten up by a drunken American sailor". Christian Blauvelt however saw merit in the film as illustrated in the battle against the brothers of Gennosuke Higaki, the original film's villain: "Their battle takes place on a snow-covered hillside and matches the natural beauty of the first film's windstorm finale. In his years apprenticing at P.C.L. , Kurosawa had become exposed to the films of John Ford, many of which played in Japan, before the foreign-film embargo that accompanied Japan's declaration of war on the United States in 1941. Like Ford, Kurosawa would emphasize the place of landscape in his films, often pairing his characters' emotional turmoil with the Elements. The rain in One Wonderful Sunday, Rashomon, or Seven Samurai, the beating sun in Stray Dog, the sinkhole in Drunken Angel, the snowfall in The Idiot, the wind in Dersu Uzala, and the crashing waves of Kagemusha would express some emotional anguish of the characters and, as a kind of cinematic synecdoche, society as a whole."
