Re: Moving beyond kihon waza
I think Kisshomaru had a major problem, when he took over the management of the Aikikai after the war. He had to systematize the waza and also make them available to cultures that had a different pedagogical method to the rigid prewar Japanese system of Ki-Sho-Ten-Ketsu (in Noh), or Shu-Ha-Ri (in most Japanese teaching / learning systems).
So, what do you do?
I think Kisshomaru's earliest book speaks volumes, as do the early books of Morihiro Saito, who wanted to add to Kisshomaru's book some very essential material related to Morihei Ueshiba's long stay in Iwama.
But you also have to have the mindset to kill or at least injure your opponent, which is something I learned from training with K. Chiba.
