- October 23, 1964

Judo is recognised definitively as an Olympic sport in Munich after being absent from the Games in 1968.
Women's judo features at the Games for the first time in Barcelona.
- Yasuhiro Yamashita (Japan)
A legend. Unbeaten over a seven-year period in which he was Olympic champion in the Open category and heavyweight world champion three times (1979, 1981, 1983) and Open category once (1981). After a series of 203 victories from October 1977, he retired in 1985.
- David Douillet (France)
One of the greatest. Olympic champion in 1996 and 2000 and triple heavyweight world champion in 1993, 1995 and 1997 and once in the open. The Frenchman weighs in at 125kg and has won it all.
- Ryoko Tamura (Japan)
Miss Judo. At just 16-years-old she won an Olympic silver in 1992, a feat she repeated in 1996 before taking gold at both Sydney in 2000 and Athens 2004. Winning bronze in 2008, she has therefore won a medal in the 48kg category at all Games since the introduction of women's judo as an Olympic sport. She was world champion six successive times between 1993 and 2003 and holds a very special place in the hearts of Japanese sports fans.
