I'm sorry about the terrible subtitles. This is the only version of the film currently available.
Unfortunately they've translated all the names from Chinese rather than Japanese.
The main character is Sugata Sanshiro, not Chee.
His teacher is Yano Shogoro (modeled on a real person named Kano Jigoro) not Master Chin. He invented judo in the 1880s. He's played by Okochi Denjiro, the actor who played Jirokichi twelve years before!
The school (not stream) that is competing with them practices jujitsu, a more traditional martial art.
Karate is a martial art invented in Okinawa and has nothing to do with this film.
The first opponent who dies during the match is named Momma.
The second opponent who is grateful to have been involved in such a great match is Murai Hansuke (Chuen). He is played by Shimura Takashi who appears in many of Kurosawa's most important films including Ikiru and Seven Samurai.
Sugata's arch-rival, and the villain of the film, is Higaki Gennosuke (Kuo).
The school that wins the big competition is set to become the official martial arts school of the police force. The competition is between the traditional school of jujitsu school and the modern school of judo. The judo folks win. This whole film is very loosely based on the true like exploits of an early student of judo. It is based on a novel written by the son of an actual student. It is also basically a rewrite of a 1930s serialized novel called Miyamoto Musashi, but with judo instead of swords and moved from the 1700s to the 1880s.
