http://www.youtube.com/watch?v=uPhG6XA2fL8A good introduction to Tomiki Aikido by the man himself. For me, I can see how his Judo background had some influence on his Aikido (not just on the introduction of Randori and competition in Aikido). And of course his Aikido had quite an influence on Kodokan Judo (amongest other things, he is one of the creators of Kodokan Goshin Jutsu kata, using both Aikido and Judo principles when creating said kata).
Just popping this up here alongside Taison's Shioda Gozo's thread, as it shows a master of Aikido demonstrating his own style. I hope to find a good clip of Minoru Mochizuki.
to complete the collection.
