Found this floating around out on the internet ... A half-hour long 1950s Japanese traditional karate training film. It gives a great variety of images from an earlier karate era, from demonstrations, to how traditional dojos train, to demonstrations by legendary masters, including Okazaki, Nakayama, Suzuki, and Kanazawa. Even an elderly Master Funakoshi makes an appearance at 21:00.
The narration, too, is just two guys talking about the film, but they give a good history of Funakoshi and modern karate.
There's also a traditional version of Bassai performed starting at 3:15.
