It’s a 30 minute long Japanese instructional / demo / documentary footage of the legendary Kyuzo Mifune – “the god of judo”, and the 4th person to achieve the rank of Judan (10th degree). Some very cool randori footage of Mifune sensei in the video and how he “nullify” the throwing techniques of his opponents is very interesting to see. Super smooth and shows how you can simply relax and ride the technique to prevent himself from being thrown.
Definitely some things to be learned by studying this 50+ year old video.
