Judo's Gentle Tiger movie DVD 1970s karate kid

This feature film is quite possibly the forerunner of the KARATE KID... it was shot in the late 1970s and tells a story of a young boy who studies Judo to find himself. The young boy; who is Japanese; is training in Judo and becomes a champion - not just on the mat but also in life. His teacher; Judo's legendary George Harris (1964 Olympian); teaches him not just the art and science of Judo; the Gentle way; but also the art of happiness. His teaching of the phrase Shabummi to his students makes the difference. The boy; who was born to a Japanese mother and an American father; finds himself living with his father who has no appreciation for the Martial Arts and only understands the language of money. Without giving away the story; the father in the end comes full circle and his son becomes a hero to the father as he teaches his father the true meaning of life through his martial arts.
