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.
The philosophy and subsequent pedagogy developed for judo became the model for other modern Japanese martial arts that developed from koryÅ« (å¤æµ, traditional schools). The worldwide spread of judo has led to the development of a number of offshoots such as Sambo and Brazilian jiu-jitsu.
