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".


The categorisation of kodokan judo is completed. The kodokan had three broad aims: physical education, contest proficiency and mental training.


Proceeding with the organisation of the kodokan and enacting the regulations of judo, Kano becomes the first Asian member of the International Olympic Committee and works for the spread of judo worldwide.

All events were held at the Palace of Sports of the Central Lenin Stadium.

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.
