For once, I have an answer here
Coach Josh, I rarely post in this forum, as I let other people typically go on and on about the nuts and bolts. But in this case, I have an answer to a lot of what's going on in your head:
In 1947 judo = jujitsu. There was no difference. If you look at a lot of the old Kodenkan stuff (danzan ryu), they called themselves judo and jujitsu interchangeably for quite some time. So judoka_UK's assessment that this is stuff you will find in a jujitsu school is correct. Jujitsu/Judo at that time was becoming popular, as more and more Japanese were willing to teach foreigners. But the big split, if you will, didn't happen till much later. And that split can largely be attributed to the rise of high-level competition judo at the Kodokan and the organizations to manage it.
I agree with you completely that the judo in the U.S. would benefit from some of this "older" material. And in fact, the school I'm attending here in Hawai'i did exactly that a couple weeks ago. We went over to the Tenri Judo school (nice judo school, btw), and did a clinic on working older jujitsu into their current judo. Everyone had fun, I think. As for myself, having done three kinds of "jujitsu" along with "judo", I can see the analogues between them pretty easily.
Ok, back to your regularly scheduled, high-end slap fight. Nice video, by the way.
Edit: Hooray for tora katsugi at 2:48! I love that one.
