| Status | Olympic | |
| Location | Olympiako Gymnastirio Ano Liosion, Ano Liossia | |
| Participants | 22 from 22 countries | |
| Format | Two single-elimination pools, with winner of each pool advanced to the final. All judoka losing to the finalists in each pool advanced to repêchage pools, with the winners of the repêchage pools earning bronze medals. | |
This was one class which definitely did not proceed as expected. The contenders were Gella Vandecaveye (BEL), the 2001 World Champion; Daniela Krukower (ARG), the 2003 World Champion; and Driulys González (CUB), three-time Olympic medalist in the lightweight class. But of those, only González would win a medal and that only a bronze. Ayumi Tanimoto of Japan was not considered a favorite, despite winning the 2001 Asian Games, but she kept winning her pool matches by ippon, including the pool final over Krukower. The other finalist was Austrian Claudia Heill, a three-time medalist at the European Championships but never a winner. In the final, Tanimoto continued her dominance, throwing Heill for ippon in only 1:17. Though she did not win any World Championship titles, Tanimoto would return in 2008 to defend her gold medal.
