I've heard that the 2nd Doshu, K. Ueshiba, was also refered to as "Waka Sensei."
I'm just curious if anyone knows why that was the case?
What does "waka" mean in this regard?
Does Moriteru Ueshiba, current Doshu, have a nickname or something similar to his father?
Just curious. I'm a stickler for trivia.
