Competitors were divided into two elimination pools with the top three in each pool advancing to the ranking round. The winner of the two ranking round pools competed in the final, with the remaining competitors competing for two bronze medals.
World champion Sandra Sánchez (ESP) and the host nation’s Kiyou Shimizu advanced to the final – fitting as they were the top two ranked competitors in the world – each winning their elimination and ranking pools fairly comfortably. The final itself was a close contest, Sánchez winning by a narrow margin to take the first ever Olympic gold medal for karate. Grace Lau (HKG) and Viviana Bottaro (ITA) completed the medal line-up.
