So, this makes me wonder if Aikido, as Ueshiba taught it, was a distillation or dilution of Takeda's Daito Ryu AJJ ?
It would be interesting to see when the change in name occured. Was it Ueshiba's pre-war Daito Ryu/Aikido or postwar Aikido when Ueshiba changed the name of the technique, possibly to distance himself and his art from DR AJJ ?
He didn't change the name, his students did as they tried to make sense of what the heck he was doing. Similar process in Daito Ryu around the same time.
