"Japanese Jujutsu focuses more on self-defense, striking, and standing grappling, especially Goshin Jujitsu. Jujutsu is the Gentle Art, and was invented is various ryus, or styles, in feudal Japan, and was perfected in the 1600's by the samurai. Jujutsu yielded the arts of Judo, Aikido, Hapkido, since Aikijujutsu was the most selective and private Ryu, and all of the Japanese styles of karate.
Judo, the sportive version of Japanese Jujutsu, is a style of submission wrestling, and is thought to be the best throwing art. Judo has over 67 throws, plus reaps/ trips, takedowns, and various breakfalling techniques to land safely after being thrown. Judo also has the best, meaning fastest chokes, with some knocking people out in as little as three seconds. And lastly, Judo contains wrestling techniques, mat holds or pins, and a lot of arm and shoulder locks, or armbars. Judo is now considered to be the most modern version of Japanese Jujutsu.
Brazilian Jiu-Jitsu, considered to be the most effective groundfighting art ever, focuses almost exclusively on groundfighting. Jiu-Jitsu comes from Judo, and was adapted by Helio Gracie to be more effective for weaker and smaller people, such as himself, as many Judo throws require either flawless technique, or else a good bit of strength. Jiu-Jitsu has the most devastating arsenal of chokes and joint-locks, and the best grappling positioning techniques. We like to say in the art, "if there's a joint, we can break it." Jiu-Jitsu has self-defense applications, but don't be fooled, it started out as a sport. Just about all of the BJJ techniques are found in Judo, and vice versa"
