Ju-Jitsu was originally a Japanese Martial Art that began with the training of the Samurai Warriors to defend themselves on the battlefields of feudal Japan. Using the sword (Katana) and other weapons, on foot and on horseback dressed in full armour made from bamboo, the Samurai went to war. The Art of Ju Jitsu was taught separately, and was to be used if the Samurai was un-horsed, and had lost his weapons. Unarmed, the Samurai would still be in a position to defend himself against both armed, or unarmed enemy. The aim was the same as with unarmed combat skills today; maim, incapacitate or kill the attacker and escape to fight again.
