Hello,
There is a kata developed for women's self-defense called Seiryu. Supposedly it was developed by OSensei Ueshiba, Toyama Sensei and Mabuni Sensei. I have seen films of it practiced by both karate groups but I have never seen it done by Aikidoka. Do any of the Aikidoka on this site practice it? Even if you don't practice it what do you think OSensei contributed to it?
