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.
Since its inception in 1882, its parent art of judo was separated from older systems of Japanese jujutsu by an important difference that was passed on to Brazilian jiu-jitsu: it is not solely a martial art, but it is also a sport; a method for promoting physical fitness and building character in young people; and, ultimately, a way (Do) of life.
