I wanted to throw out some food for thought for Aikido folks. A common response to pointing out issues with various techniques is that they work the way that they do because uke is smart enough to know when to “take the fall” and that failing to do so would result in significant injury. I know this was how kotegaeshi and many other techniques were explained to me when I started Aikido, but in my time working with different ideas about aiki and looking at the more controlling techniques of judo, jujutsu, and aikijujutsu, I really don’t buy that argument anymore, particularly in the case of Aikido where supposedly we are learning a non-violent system where we learn to safely respond to an attacker protecting ourselves AND them from harm. In my mind you cannot be learning effective techniques that protect both parties AND learning techniques that are actually designed to injure your opponent unless they perform specific acrobatics at the right time.
As an analogy, let’s look at a totally different scenario: let’s say I was learning a sword kata where tori (the do-er) cuts uke/uchitachi’s legs out from under them at the knees. Since this is a class and legs are expensive, in the kata uke takes a forward tumble over the sword swing and rolls. Here we have a technique (a sword cut) that results in a “throw” in that uke is forced to take acrobatic measures to avoid injury. I would not say that the person with the sword was learning how to throw someone here. The intent is to cut the legs, not to throw the person. I also wouldn’t consider this a non-violent solution to the attack even though in the kata, no one is injured due to uke’s acrobatics. The goal and the intent is to do harm to the attacker, but for safety purposes (and because we’re not sadistic) we have introduced a way for uke to participate safely. However, this kata could not be performed as-is on someone who did not know how to perform difficult acrobatics and who was not in on the timing and pattern of movement. For the cut to be effective, it needs to happen in such a way that it CANNOT be dodged. The swordsman, being presented an opportunity in real life to perform this move would not be trying to throw the other person, but would be cutting their knees. We actually see these kinds of accomodations in most weapon based arts and even many older Japanese Jujutsu. For example, one of the comparable techniques to Aikido’s kotegaeshi in Araki ryu is performed so that no ukemi is possible in order to guarantee the injury of the opponent. In Yagyu Shingan Ryu, ukes often perform assisted cartwheels as ukemi. This looks very odd and un-martial to the outside observer until you realize that these techniques were designed to invert an opponent and then break their neck. You run out of students that way rather quickly, so the ukemi becomes stylized to allow nage to practice right up to the moment when the technique would become injurious. The kata isn’t about how to help someone cartwheel, it’s designed to break their neck.
In Aikido we have a problem though. It’s generally accepted (and marketed) that this is a non-lethal, non-injurious art that allows someone to defend themselves while also protecting their attacker. I would assert that if the techniques you are doing only work because your partner is in on the gag and is performing acrobatic ukemi to prevent injury, that’s not the same thing at all. That would be the equivalent of the swordsman believing they were learning how to throw someone by cutting at the knees. If your goal is to punch the person in the face but they throw themselves for a hard fall to avoid that, maybe skip all the spinning around and just do some boxing? It’s far more efficient at learning how to punch someone in the face. To put it another way, would you be able to perform what you are learning as non-injurious on someone who DIDN’T know how to perform acrobatics? Someone who didn’t know WHEN they needed to throw themselves? If not, what are you really learning and is it morally in keeping with how you describe your art? If your only recourse IRL is to do harm and injure, I suggest you come to terms with that and stop hiding behind a façade of false benevolence. Personally, while I’m not opposed to studying injurious or lethal techniques, I believe that all of my throws should work as intended without my uke being in on it. I do not need my partner to know how to fall from my throws or how to respond to my movements. I can perform my version of kotegaeshi on someone off the street who has no idea what the technique is supposed to look like or how to fall down without injury. I have the CHOICE to injure or protect due to the amount of control I have during the encounter. Injuring someone because they didn’t respond correctly to you is a very odd manifestation of non-violence in my opinion and is really a sign of behavioral conditioning. This creates a false sense of skill in nage and sets the stage for abuse and victim blaming in the event of injuries. “It wasn’t my fault. He broke his own wrist by not being ready…”
