Modern ju-jitsu in JJIF knows four different competition systems:
1. Fighting System;
2. Duo System;
3. Self Defence System;
4. Ne-waza System.
Competitors in ju-jitsu are wearing white jujitsu-gi (kimono) in proper size.
JJIF Fighting system allows athletes to compete in two gender categories (male/female), six age categories (boys/girls, aspirants, juniors, seniors) and further more in many more weight categories in each class.
Competition is organised on the soft mats (i.e. judo mats), conducted by three referees on the mat (called mat referee and side referees) and one at the (soccer) table. There is only one match (round) of 3 minutes.
System is composed from three parts (this distribution is important for scoring as the fights are very fluent and in principle do not stop even if a point is achieved. Competitors may proceed from part one to part three and back. ):
Part one - punches, strikes and kicks: opponents are standing in the middle of the mats, they start when mat referee says “hajime”... Only semi-contacts are allowed.
Part two - throws, take downs, locks and strangulations: after establishing contact no punches, strikes or kicks are allowed any more (there is an exception in the rules if they are enforced simultaneous with the grip);
Part three - floor techniques, locks and strangulations: when opponents are on the ground different ground techniques are allowed.
Ippon and waza-ari are points given in ju-jitsu fighting system. Ippon represent 2 points (in part two and three eventually even three points in case then one of competitor surrenders); waza-ari represents 1 point. In principle the fighter with more points after 3 minutes is a winner. Rules presume also winning before the end or regular time (per example if one has achieved ippon points in all three parts).
The JJIF-Duo System is aimed at presenting the defence (by their choice) of one contestant against a number of predetermined attacks from a contestant of the same team. One couple (categories are male/male, female/female, male/female in 4 different age categories) is actually competing to another couple.
The attacks are divided into 4 series of 5 attacks each:
A. Gripping attacks
B. Embracing and neck lock attacks
C. Punches, strikes and kicking attacks
D. Weapon attacks
Every attack must be prepared by one pre-attack such as pushing, atemi, pulling.
When on the mat the referee shows the number of three attacks from
Criteria of judging - the jury shall look for and judge the following:
1. Powerful attack
The overall score should give more importance to the attack, and to the first part
of the defence. Atemis must be powerful, with good control and given in a natural way considering possible follow up. Throws and take-downs shall include breaking the opponents balance and be efficient. Locks and strangulations must be shown to the jury in a very obvious and correct way, with tapping by Uke.
Both the attack and the defence shall be executed in a technical and realistic way.
A jury of five referees is scoring each series of three attacks with points from 0 to 10, with half points. The highest and the lowest of points are taken away. At the and the couple received more points in all four series is the winning one.
The Self-Defence Department for the Army, the Police and the Security Companies to JJIF (the Ju-Jitsu International Federation), aims to assist the education of the officers from the law-enforcement bodies; one of the ideas is to carry out championships.
The “Security Self-Defence” Discipline, represents a demonstration of defence against different types of attacks between competitors from one team. The attacks are defined and systemized in 4 groups – each one consisting of 4 attacks. The competitors are free to choose for themselves the defence technique to be used.
OTHER WAYS TO COMPETE
National federations are encourages to create and practice also other ways on competitions on the national level, not covered with international rules. These are usually competitions or events for younger categories (i.e. technical competitions as the fighting competitions, combined with the ju-jitsu techniques they learn with the first steps on the mat etc.).
... and of course, at the end – competition and competing is not the only way we do like ju-jitsu.
