Jujitsu is an umbrella term for Japanese styles, with a Samurai lineage. Judo is a specific style of Jujitsu that focused on training safely with resistance, and evolves based on the results of training with resistance.
Aiki-jujutsu is differentiated from jujutsu in that instead of using muscular strength within technique, Aiki-jujutsu requires the opposite -- that the defender?s external muscles be totally relaxed.
