STARS
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. She has therefore disputed the judo final in the 48kg category since its introduction 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.
