JAPANESE JIU JITSU
Japanese Jiu Jitsu (also known as JuJitsu or JuJutsu) is a Japanese martial art & method of close combat for defeating an armed & armored opponent in which one uses no weapon or a short weapon.
"Ju" can be translated to mean gentle, supple, flexible, pliable or yielding.
"Jutsu" can be translated to mean art or technique & represents manipulating the opponents force against himself rather than confronting it with one's own force.
Jiu Jitsu evolved among the samurai of feudal Japan as a method for defeating an armed & armored opponent. Because striking against an armored opponent proved ineffective, practitioners learned that the most effective methods for neutralizing an enemy took the form of pins, join locks & throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.
There are many variations of the art, which leads to a diversity of approaches. Jiu Jitsu schools (RYU) may utilize all forms of grappling techniques to some extent (throwing, trapping, joint locks, holds, gouging, disengagements, striking, kicking, etc.). In addition, many schools teach the use of weapons.
