Bujutsu refers to ancient Japanese Martial Arts. It combines the characters for “war” (武, bu) and “technique” (術, jutsu). Bujutsu includes both armed and unarmed techniques and was originally practiced by Samurai Warriors in Japan. While numerous external techniques and schools of bujutsu still exist in Japan,  we are solely focusing on the Internal Skills developed by the Samurais over a thousand years in the battlefields, which comprise specific training methods to condition, organize and utilize the body to control and defeat their opponent in an instant without relying on external physical strength while depriving the opponent of information.
