Judo - What's it all about?

Many assume that all martial arts focus simply on attacking and are tests of power and strength.

Judo is different - as competitors must practice "gentleness" or "first giving way" in order to ultimately gain victory.

The word "Ju" simply means gentle - and the word "do" means "the way". Judo, therefore, is the "gentle way".

In a lecture he gave at the University of Southern California alongside the 1932 Summer Olympics in Los Angeles, judo's founder Kano Jigoro Shihan sought to explain.

"Suppose we assume that we may estimate the strength of man in units of one," said Kano, who started his own school, the Kodokan. 

"Let us say that the strength of a man standing in front of me is represented by ten units, whereas my strength, less than his, is represented by seven units. 

"Then if he pushes me with all his force I shall certainly be pushed back or thrown down, even if I use all my strength against him. 

"This would happen because I used all my strength against him, opposing strength with strength.

"If, instead of opposing him, I were to give way to his strength by withdrawing my body just as much as he had pushed, remembering at the same time to keep my balance, then he would naturally lean forward and thus lose his balance." 

This is not to say that judo does not feature direct attacks. The sport should be considered as the principle of maximum efficient use of mind and body, combining attack and defence.

Kano believes that these principles - and the desire for maximum efficiency - can be adopted in all areas of life.

"It can at the same time be applied to the improvement of diet, clothing, housing, social intercourse and methods of business, thus constituting the study and training of living," he said. "I gave this all-pervading principle the name of 'judo'.

"So judo, in its fuller sense, is a study and a method of training in mind and body as well as in the regulation of life and affairs. Judo, therefore, in one of its phases, can be studied and practiced with attack and defence as its core activity." 

Kano began instruction in judo in two forms - randori and kata

Randori, meaning "free practice" is carried out under conditions of an actual contest. It includes throwing, choking, holding the opponent down and bending or twisting the arms or legs.

Kata is a series of prearranged exercises, including hitting, cutting, kicking and thrusting. 

 "Judo is a study and a training in mind and body as well as in the regulation of one's life and affairs," said Kano.

"The final aim of judo is to inculcate in the minds of people a spirit of respect for the principle of maximum efficiency and of mutual welfare and benefit."

Jigoro Kano makes a comprehensive study of the ancient self-defence forms and integrates the best of these forms into a sport which becomes known as kodokan judo. The term kodokan breaks down into ko (lecture, study, method), do (way or path), and kan (hall or place). Thus it means "a place to study the way". Similarly judo breaks down into ju (gentle) and do (way or path) or "the gentle way".

Judo becomes an official event in the Olympic Games of Tokyo, backed by judo fans and sport promoters all over the world. Medals were awarded in four classes, and competition was restricted to men only. The competition was held in the Nippon Budokan, which was built to host the competition. Japanese victories for lightweight Takehide Nakatani, middleweight Isao Okano and heavyweight Isao Inokuma put them top of the medals table. The Netherlands' Anton Geesink wins the open category.

Judo competition at the Olympics in Moscow marks the first time that the medal table was not dominated by Japan, since the country joined the boycott of the Games because of the Soviet invasion of Afghanistan the previous year. Medals are awarded to male judoka in eight competitions, seven weight classes and the open competition - two more than in 1976. All events were held at the Palace of Sports of the Central Lenin Stadium. The Soviet Union and France claim two gold medals each, while East Germany, Belgium, Italy and Switzerland earn one apiece.

With the open division, there are eight competitions, which are restricted to male judoka. Japan returned to the top of the medal table, after boycotting the Moscow Games. Because of the Soviet-led counter-boycott of the Los Angeles Games, several traditionally strong judo countries, including Cuba and the Soviet Union, do not participate.

Judo at the Olympic Games in Athens takes place at the Ano Liossia Olympic Hall, where 368 judoka compete for 14 gold medals with seven different weight categories in both the men's and women's competitions. Japan dominate the event by taking eight gold and two silver medals. There is controversy in the men's competition, when Iranian competitor and two-time world champion Arash Miresmaeili weighs in overweight and is disqualified before a match in which he would have faced Israeli judoka Ehud Vaks. Miresmaeili's comments strongly suggested that he had intentionally disqualified himself so as not to compete against an Israeli. "Although I have trained for months and was in good shape I refused to fight my Israeli opponent to sympathise with the suffering of the people of Palestine and I do not feel upset at all," he says.
