Come to think of it, I am still struggling with Heian Nidan ;-)
I don't know what these were shot on, but for me the weird color and muddy focus only add to the charm. Click on the bold hyperlinked title to see the videos!
What I love about this video is that it clearly shows an earlier stage in the evolution of IS slow-motion training to the level he trains at now. One of the things you have to remember with IS is that kicking fast and high is easy. Kicking slow is a different matter. As an aside, just before we went off to Norway, I saw IS walk up to the bag at the other end of the ShotoKan. He lurked in front of it and then suddenly POP! out came a fast as lightning left jodan mawashigeri that hit the top of the bag. He then turned around and wondered off absent-mindedly as if he was thinking about his lunch or something. That's Isaka Sensei. No matter what you think he's thinking, he's thinking something else. You think he's going to kick one way, but he's already somewhere else.
This reminds me of Asai Sensei- he seemed to have a temporary anti-gravity button. With Isaka Sensei, it's a sort of appear where you don't expect him. Difficult to explain, you just have to see it.
Here we can see YS with knives, Asai Sensei looking very deadly with nunchacku, and a rare ushirogeri from YS. The big point for me is that this was apparently filmed back in 1980, and yo can see the early elements of YS spinning techniques that became so important later.
Just take a look at this. Most of this will be familiar to YS watchers. But there is a lovely surprise at the end.
Here is a full chance to appreciate a couple of Asai Sensei's Budo techniques. What a pity there aren't more. It's just a delight to watch. And some clips of Isu-Dori as well ;-)
