Re: Why these techniques?
"I don't know, samurai did not box nor wrestle."??? Wrong answer... they did both... they just called them by japanese names...
Xu...so samurai always wore armor and were on a bloody battlefield 24/7??? this is silly... aikido was derived from various Jiujitsu that were meant to address the battlefield AND everything else including striking, kicking and groundwork... do the research... you can find scrolls that show 'non-battlefield/fully armored' applications... the arts were equally weapon and empty hand... anything else would just be dumb... that is the "why" and it justifies BOTH weapons and empty hand... It must also be effective otherwise why did it survive? Why would you practice something that is not effective???
It is necessary to develop a strategy that utilizes all the physical conditions and elements that are directly at hand. The best strategy relies upon an unlimited set of responses.
PS. Perhaps english is not your primary language, Meynard?... 'empty hand weapon based martial art' this makes no sense... it is self contradictory... if it is empty hand then it is not weapon based, and if it is weapon based it is not empty hand... it can be BOTH an empty hand and a weapon based martial art equally... but combining the terms cancels each other out...
