Japan won three golds on the fourth and final day of the International Judo Federation World Junior Championships in Nassau in The Bahamas.
Wada Rinoko won Japan's first gold of the day in the women's under-78 kilograms event, by defeating Junior European Championships bronze medallist Karla Prodan of Croatia.
The former cadet world champion was beaten as the Japanese judoka threw her twice to take the title and start a golden day for her country at Atlantis Paradise Island.
Junior European champion Patricia Sampaio of Portugal claimed the first bronze with two waza-ari scores to take her second world bronze against Germany's Teresa Zenker.
The second bronze medal was won by Britain's Shelley Ludford, who claimed her country's first medal in The Bahamas.
Ludford's opponent, Brazil's Camila Ponce, was disqualified for a waki-gatame.
In the final women's category of the Championships, Japan took another gold as Kodama Hikaru upset Brazil's Beatriz Souza for the over-78kg title.
Souza is ranked as number ten in the world at senior level and is a Tokyo 2020 Olympic Games contender, but she could not escape the Japanese judoka's pin.
Kodama upgraded her silver medal from last year as she pinned Souza for gold.
The bronze medals went to France and Germany.
Laura Fuseau of France edged past her Hungarian opponent Mercedesz Szigetvari with a waza-ari from a uchi-mata in a one-score match.
Germany's Renee Lucht took the second bronze as Kazakhstan's Kamila Berlikash was penalised for a third and final shido in golden score.
Japan's third gold came in the men's under-100kg event as Sekine Kiyotaka beat the former cadet world champion, Simeon Catharina from The Netherlands.
Nothing separated the two judokas in normal time but Sekine produced a ko-uchi-makikomi after 17 seconds of additional time to take the title.
Georgia took the first bronze medal as Onise Saneblidze threw Canada's Shady Elnahas for a waza-ari score and held on for the victory.
Poland also made the podium through Iwo Baraniewski who scored against Denmark’s Mathias Madsen with just two seconds left on the clock.
The final contest of the Championships was the men's heavyweight division, with Georgia taking the spoils.
The Junior European champion Gela Zaalishvili defeated Austria's Stephan Hegyi, who is ranked tenth on the senior world ranking list.
Zaaslishvili threw his opponent for waza-ari and then pinned Hegyi for ten seconds to take the victory.
Erik Abramov of Germany took the first bronze medal in dramatic fashion as he produced an ippon after just 42 seconds to take the medal over Slovenia's Enej Marinic.
The 2015 cadet world champion, Kemal Kaitov of Russia, then lost out to his team-mate Dzhamal Gamzatkhanov in an all-Russian bronze medal contest.
Gamzatkhanov tapped out his team-mate for a place on the podium.
