Jujutsu (/dʒuːˈdʒuːtsuː/ joo-JOOT-soo; Japanese: 柔術, jūjutsu ) is a Japanese martial art and a method of close combat for defeating an armed and armored opponent in which one uses no weapon or only a short weapon. 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 (i.e. throwing, trapping, joint locks, holds, gouging, biting, disengagements, striking, and kicking). In addition to jujutsu, many schools teach the use of weapons.
