| Status | Olympic | |
| Location | Jang-chung Che-yuk-gwan, Seoul | |
| Participants | 42 from 42 countries | |
| Format | Two single-elimination pools, with winner of each pool advanced to the final. All judoka losing to the winner of each pool advanced to repêchage pools, with the winners of the repêchage pools earning bronze medals. | |
The favorite was the 1987 World Champion, Japan’s Yosuke Yamamoto. In winning that title, he had defeated the 1985 World Champion, Yury Sokolov (URS), in the final. Sokolov was also in Seoul. More lightly regarded was Korean Lee Gyeong-Geun, who had been runner-up in 1985 to Sokolov. In the first round, Sokolov lost to former European Champion Bruno Carabetta (FRA), basically eliminating him from medal contention. The pool finals matched Yamamoto against unheralded Pole Janusz Pawłowski, and Lee against European Champion Tamás Bujkó. Yamamoto was not expected to have trouble, but Pawłowski threw him with ippon-seoi-nage to advance to the final. Lee won the other pool final with ippon from a hold, after dominating the Hungarian. The final was very close. Lee won, but only by decision (yusei-gachi) at the time limit.
