Jujutsu, also known as jiu-jitsu and ju-jitsu, is a family of Japanese martial arts and a system of close combat that can be used in a defensive or offensive manner to kill or subdue one or more weaponless or armed and armored opponents. It was coined by Hisamori Tenenuchi when he officially established the first school of jiu-jitsu in Japan. 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.
