Japan won a pair of gold medals for the second consecutive day as the inaugural International Judo Federation Grand Prix continued in Montreal.
Soichi Hashimoto topped the podium for the Tokyo 2020 hosts in the men's under-73 kilograms category with Takanori Nagase doing the same in the men's under-81kg.
Their successes followed victories on the opening day for Naohi Takato in the men's under-60kg and Wakana Koga in the women's under-48kg, with Japan warming up nicely for their home Olympic Games next year.
Hosts Canada also enjoyed a good day at the Maurice Richard Arena, winning four medals, while there were golds for South Korea and Germany.
Hashimoto defeated the United Arab Emirates' Victor Scvortov via an arm-lock ippon for his gold medal with Canada's Antoine Bouchard and Germany's Anthony Zingg both winning bronze.
Home hopes were dashed in Nagase's final as the Japanese nailed Canada's Antoine Valois-Fortier with an uchi-mata for a big ippon.
Bronze medals were shared by Belgium's Matthias Casse and Russia's Aslan Lappinagov.
South Korea's Mokhee Cho was considered the surprise package of the day as she won the women's under-63kg division.
She threw Britain's Amy Livesey for ippon in the golden score period to claim top honours.
Canada's top seed Catherine Beauchemin-Pinard had to settle for bronze after a semi-final defeat to Livesey, with Alexia Castilhos also taking a share of third place.
Germany's Giovanna Scoccimarro claimed her first success at senior level in the women's under-70kg class.
There was more disappointment for Canada as Kelita Zupancic was beaten in the final after launching an attack which was out of control, allowing the German to pin her for ippon.
Megan Fletcher of Ireland and South Korea's Seongyeon Kim won bronze medals.
The final day of competition tomorrow will include France's reigning double Olympic champion Teddy Riner in the men's over-100kg class.
The 10-time world champion has not competed since November 2017 but has targeted a third gold at Tokyo 2020.
He has not lost a bout since 2010, a winning streak of 144 matches.
