I am back from 9 days in Tokyo training with Akuzawa and Rob. Last year there was quite a bit of discussion about Akuzawa's Aunkai method here on E-budo.
The Aunkai folks were gracious hosts and the training was first rate. I got to feel Akuzawa's kicks as well as the hand raising exercise (age te) from kneeling. He had the hardest kicks I have ever felt, to include pro fighters from China.
More importantly, he can _teach_ what he is doing to his students. That's what is most significant to me because no matter how good a person is, I'm not too interested if they can't/won't teach.
I know some of you have already met Rob, but there are other students as well who also have developed pretty impressive skills. Static demos are impressive enough, but fighting is a whole other deal entirely. While I was in Japan I went with Rob and Manabu (who was originally a Systema practitioner) to an open mat wrestling session with some shooto (MMA) guys, and Manabu more than held his own against the shooto players, one of whom is a pro fighter. Another one of the Aunkai guys , Mitsuhashi is an experienced grappler/mma player and is making the transition to the internal style of training.
For people who are more interested in practice on the aikido-esque side of things, I should mention that Akuzawa demonstrated the age te exercise several times. At one point my friend who is a weightlifter type guy, around 185 lb., piled onto Akuzawa's wrists. Akuzawa threw him backwards effortlessly.
Akuzawa explained several times that his goal is pure motion, and to move without regard for the opponent , by focusing on keeping his own frame. Therefore a step is a step, or a kick, or a sweep.
From other people I have seen, this is just talk. Akuzawa, however, is the real deal.
