Brazilian jiu-jitsu is a martial art and combat sport system that focuses on grappling and especially ground fighting. Brazilian jiu-jitsu was formed from Kodokan judo ground fighting (newaza) fundamentals that were taught by a number of individuals including Takeo Yano, Mitsuyo Maeda and Soshihiro Satake. Brazilian jiu-jitsu eventually came to be its own combat sport through the experiments, practices, and adaptation of judo and jujutsu through Carlos and Hélio Gracie (who passed their knowledge on to their extended family) as well as other instructors who were students of Maeda, such as Luiz França.
BJJ promotes the concept that a smaller, weaker person can successfully defend themselves or another against a bigger, stronger, heavier assailant by using proper technique, leverage, and most notably, taking the fight to the ground, and then applying joint locks and chokeholds to defeat the opponent. BJJ training can be used for sport grappling tournaments and in self-defense situations.
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; it is also a sport, a method for promoting physical fitness and building character in young people, and ultimately a way of life
