Here are a couple of you-tube videos of Judo legend Masahiko Kimura. Kimura is regarded as one of the greatest judoka of all time and he also studied karate under Gichin Funakoshi (Shotokan) and So Nei Chu (Goju) - becoming an assistant instructor of the latter’s dojo - and he also had connections with karate greats Gogen Yamaguchi and Mas Oyama. Kimura’s bout with Hélio Gracie is why the reverse ude-garami is frequently called “The Kimura” in BJJ and MMA.
Mas Oyama once wrote, “As one of my Senpai, there was a judo master named Masahiko Kimura. In judo, simply there has never been a man as strong as this man was. He was such a master in the art of judo to the extent that is frequently said: ‘There has been no Kimura before Kimura. There will be no Kimura after Kimura.’”
I hope you find the clips interesting.
All the best,
