Summary

Ju-Jitsu (Japanese: 柔術 jūjutsu, also spelled Jujutsu or Jiu-Jitsu) is a Japanese martial art that focuses on grappling, joint locks, throws, and submissions to neutralize opponents. It originated as a battlefield combat system used by samurai to fight armored opponents when weapons were not an option.

There are different styles of Ju-Jitsu, including:

• Traditional Japanese Ju-Jitsu – The classical form emphasizing joint locks, throws, and strikes.
• Brazilian Jiu-Jitsu (BJJ) – A modern adaptation that focuses on ground fighting and submissions.
• Sport Ju-Jitsu – A competitive form that includes striking, throwing, and grappling, often seen in organizations like the Ju-Jitsu International Federation (JJIF).

Sport Ju-Jutsu

Ju-Jitsu has influenced many modern martial arts, including Judo and MMA.

There are many types of sports jujutsu. One version of sports jujutsu is known as "JJIF Rules Sport Ju-Jitsu", organized by Ju-Jitsu International Federation (JJIF). The JJIF is a member of GAISF and has been recognized as an official sport of the World Games.

Sport jujutsu comes in three main variants. In Duo (self-defense demonstration), both the tori (attacker) and the uke (defender) come from the same team and demonstrate self-defense techniques. In this variant, there is a special system named Random Attacks, focusing on instilling quick reaction times against any given attack by defending and countering. The tori and the uke are also from the same team but here they do not know what the attack will be, which is given to the tori by the judges, without the uke's knowledge.

The second variant is the Fighting System (Freefighting) where competitors combine striking, grappling, and submissions under rules which emphasize safety. Many of the potentially dangerous techniques such as scissor takedowns, necklocks and digital choking and locking are prohibited in sport jujutsu. There are a number of other styles of sport jujutsu with varying rules.

The third variant is the Japanese/Ne Waza (grappling) system in which competitors start standing up and work for a submission. Striking is not allowed.

Other variants of competition include Sparring, with various rule sets. Ground fighting is similar to BJJ, Kata, and Demonstrations.

Sparring and ground fighting can have various rule sets depending on the organization. Kata can be open hand or with traditional Jujutsu weapons and Demonstrations can be in pairs or teams of up to 7.
