In the first round she faced Tatum Keen (GBR) and scored a first waza-ari after 1:34 minute, concluded two minutes later with an immobilisation for ippon. Mireia Lapuerta Comas (ESP) was not more successful than Keen and was defeated by Omori with harai-goshi for waza-ari, a throw she duplicated a little later but for ippon. In the semi-final, it was Roza Gyertyas (HUN) who found no solution to beat the Japanese judoka, who was much too strong today.
It remained to be seen who her opponent would be in the final and it was Ayumi Leiva Sanchez (ESP) who came out of the preliminary rounds as the winner, after eliminating Darja Mihhailova (EST) with an unstoppable shime-waza, then Naomi Van Krevel (NED), with a seoi-otoshi, counted as a first waza-ari, then a sasae for a second score. In the semi-final Ayumi Leiva Sanchez defeated Tereza Bodnarova (CZE).
The two judoka offered a tough battle during normal time, Omori being more dangerous with her traditional Japanese-style of judo, while Ayumi Leiva Sanchez was dangerous every time she would throw her left arm over Omori's shoulder to launch her sumi-gaeshi. They neutralised each other and had to enter the golden score phase. That's when Omori applied one of the Japanese specialties, a ne-waza turn-over followed by an unstoppable osae-komi for ippon. It was a second gold for Japan.
Aydan Valiyeva (AZE) and Tereza Bodnarova (CZE) faced off in the first match for a bronze medal. With a brilliant counter-attack, Bodnarova scored ippon to take that bronze medal.
The second match for a bronze medal was between Leonie Gonzales (FRA) and Roza Gyertyas (HUN). Under pressure, Gonzales was penalised twice, leaving no space for any more mistakes. But it was under pressure that the French was better and countered her opponent with o-soto-gaeshi for waza-ari. This bronze medal was for France, the third of the day.
