Brazilian Jiu-Jitsu?
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 art through the experiments, practices, and adaptation of judo through Carlos and Hélio Gracie.
