Mifune accepts challenges from high level students
This is a fantastic old film of one of the greats of Judo, Mifune Kyuzo sensei (10th dan). If only there were as comprehensive film records of the greats of Kendo like Mochida, Ogawa, Saito et al.
Even though I'm no Judo man, it's great to see Mifune's softness, "like an empty jacket" as one of the commenters puts it. I have no doubt that any of his challengers would put me flat on the mat in a heartbeat! The other thing I find astounding is the range of ways that Mifune disrupts his opponents' attacks.
If you watch this on Youtube and see the links you might be tempted to watch some modern videos from the IJF. If you do, you'll see amazing athleticism, but be warned you'll also see such awful reiho that your eyes will bleed.
