judo vs. bjj

[Knifefighter]

Judo comes from Jujutsu. Kano turned Judo into a massive commercial product through exciting tournaments and heavy sparring (just like MMA is doing to TMA). Limiting it to a sporting aspect. Traditional Japanese JJ includes all of what you stated, including eye strikes, throat strikes, small joint manipulations (fingers, toes)...but these are unsporty and difficult or even impossible to spar at 100% in any dojo (ie. you can only pretend to eye strike someone). While you can spar and compete at 100% in Judo with rules.

Kano's basic thesis was that, since Jujutsu's "deadly techniques" could not be practiced at full force, they were ineffective. He used his philosophy of full out training with safer techniques to challenge the jujutsu guys and, basically, smashed them.

Pretty much the same principle used the modern full contact "sport" styles vs. traditional "deadly styles" challenge matches like these:
