Jujitsu (Japanese: 柔術 jūjutsu listen (help·info)), also known as jiu-jitsu and ju-jitsu, is a family of Japanese martial arts and a system of close combat (unarmed or with a minor weapon) that can be used in a defensive or offensive manner to kill or subdue one or more weaponless or armed and armored opponents. This form of martial arts uses few or no weapons at all and includes throws, holds, and paralyzing attacks against the enemy. Jujutsu developed from the warrior class around the 17th century in Japan. It was designed to supplement the swordsmanship of a warrior during combat. A subset of techniques from certain styles of jujutsu were used to develop many modern martial arts and combat sports, such as judo, aikido, sambo, ARB, Brazilian jiu-jitsu, and mixed martial arts. “Jū” can be translated as “gentle, soft, supple, flexible, pliable, or yielding”, and “jutsu” can be translated as “art or technique”. “Jujutsu” thus has the meaning of “yielding-art”, as its core philosophy is to manipulate the opponent’s force against themself rather than confronting it with one’s own force. Jujutsu developed to combat the samurai of feudal Japan as a method for defeating an armed and armored opponent in which one uses no form of weapon, or only a short weapon. Because striking against an armored opponent proved ineffective, practitioners learned that the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker’s energy against them, rather than directly opposing it.
There are many variations of the art, which leads to a diversity of approaches. Jujutsu schools (ryū) may utilize all forms of grappling techniques to some degree (e.g., throwing, takedowns, leg sweeps, trapping, pins, joint locks, holds, chokeholds, strangulation, gouging, biting, hair pulling, disengagements, striking, and kicking). In addition to jujutsu, many schools teach the use of weapons. Today, jujutsu is practiced in both traditional self-defense oriented and modern sports forms. Derived sport forms include the Olympic sport and martial art of judo, which was developed by Kanō Jigorō in the late 19th century from several traditional styles of jujutsu, and sambo and Brazilian jiu-jitsu, which were derived from earlier (pre–World War II) versions of Kodokan judo that had more emphasis on ground fighting (which also caused the creation of kosen judo).
