Karate Sensei profiles one of the pioneers of Okinawan Karate in the United States, Eihachi Ota. Through kinetic training footage in his Los Angeles dojo and narration by Japanese American actor Mako, Karate Sensei reveals a man dedicated to teaching the craft and history of karate.
New Jersey teen Daniel LaRusso moves to Los Angeles with his mother, and soon strikes up a relationship with Ali. He quickly finds himself the target of bullying by a group of thugs, led by Ali's ex-boyfriend Johnny, who study karate at the Cobra Kai dojo under ruthless sensei John Kreese. Fortunately, Daniel befriends Mr. Miyagi, an unassuming repairman who just happens to be a martial arts master himself. Miyagi takes Daniel under his wing, training him in a more compassionate form of karate for self-defense and, later, preparing him to compete against the brutal Cobra Kai.
