London, England (Sports Network) - North Korea's An Kum Ae won the women's 52- kilogram judo event Sunday and Georgia's Lasha Shavdatuashvili earned gold in the men's 66kg.
Both divisions saw the favorites knocked out early on in the tournament.
Japan's Misato Nakamura was the favorite for the 52kg, but was defeated by An, who later bested Cuba's Yanet Bermoy Acosta in the gold medal match.
An became the second representative for North Korea to win multiple judo medals, having also taken silver in the 2008 Beijing Games.
"I am very happy to win the gold medal," said An. "I think I was able to bring some glory to my nation."
Shavdatuashvili didn't have to go through Russian favorite Musa Mogushkov -- he failed to win his first match -- and landed a win over Miklos Ungvari of Hungary to claim the gold.
"Some months ago I could not even imagine taking part in the Olympic Games. I had just transferred from juniors," said Shavdatuashvili, who at 20 was the youngest competitor in the 66kg.
Sunday's bronze medals in the men's 66kg went to Japan's Masashi Ebinuma and Cho Jun-Ho of South Korea, while Italian Rosalba Forciniti and France's Priscilla Gneto captured bronze in the women's 52kg.
