The atmosphere was boosted by Brazil ending Japan's stranglehold on the two-day competition when Eduardo Santos overcame Toshimasa Ogata in the final of the under 81 kilograms to clinch the gold medal. 

The Beijing 2008 Olympians rolled back the years to recapture the form he showed when winning the bronze medal at the the 2010 South American Games in Medellín.

Brazil also claimed both bronze medals courtesy of Igor Pereira and Edu Ramos.

There was more Japanese success in the women's under 63kg division when 2011 world cadet champion Kaho Yonezawa overcame Britain's Bekky Livesey in the final.

Jessica Santos and Erika Ferreira each claimed Brazilian bronzes.

More than 105 athletes in four weight classes participated.

They included competitors from France Britain, Germany, Japan and Lebanon plus 15 different Brazilian teams.

“It was really an excellent event," said IJF head sports director Vladimir Barta.

"We can say that we have tested everything, even the public, which was really amazing.

"We have a nice venue and the domestic staff is simply really good."

Brazilian Sports Minister George Hilton and Rio 2016 President Carlos Nuzman were among the spectators today.

“It was a really good test event, where the main aspect was the great collaboration between our teams and the amazing atmosphere that prevailed throughout the competition," added Larisa Kiss, director of the IJF Presidential office.

"We are pleased with the progress of the organisation as far as our sport is concerned and we are confident the judo event will be successful in the Olympic Games.“
