Thanks for posting these links! I've stumbled across a few of these videos before, but with the exception of the first link I think these videos are very impressive. Most of the videos claiming to be aikijujutsu that I've seen on youtube from the US anyway, in my not so humble opinion, just look like sloppy aikido to me. And yet they claim to be somehow more effective than aikido?
I came across a four man randori from an "aikijujitsu" dojo recently, somewhere in the south I think, where the uke's were waiting to attack nage, one at a time. I wish that the uke's would be so nice at my dojo where we practice "soft" aikido!
Woops, sorry that's off topic. I'll wrap this up by stating that that aikijujutsu woman in those ogawa ryu videos could kick my sorry butt! I love it! Does anyone know if that ryu has dojos in the US?
