Despite having similar names, Japanese Jiu-Jitsu and Brazilian Jiu-Jitsu are different.
You might be wondering, "What is it that makes them so different?" If so, you've come to the right place to find some answers.
Japanese Jiu-Jitsu (JJJ) is an unarmed fighting martial art that was used by ancient Samurai.
Originally it was designed to be used if you became unarmed in combat or had to fight without a weapon. Eventually, the practice became more ritual than practical - a gentle art more than a fighting technique.
Japanese Jiu-Jitsu uses a variety of techniques including standing locks and throws in addition to ground fighting.
Brazilian Jiu-Jitsu (BJJ) was adapted from Japanese Jiu-Jitsu as a form of self-defence by the Gracie family (and others) after the Japanese introduced Jiu-Jitsu to Brazil.
Compared to Japanese Jiu-Jitsu, Brazilian Jiu-Jitsu is more focused on ground fighting and grappling. It has become a popular sport around the world and is a technique that is commonly used in UFC and mixed martial arts (MMA) fights.
Used correctly, Brazilian Jiu-Jitsu is a good method for taking on larger opponents but it can take more time because of the loss of momentum that occurs when both fighters are on the ground.
