The 37-year-old, silver medallist at the 2012 Olympic Games in London, rolled back the years with a vintage performance at the Papp László Budapest Sportaréna.

Ungvári, a three-time European champion, secured victory in front of his home crowd as he beat Japan's three-time world champion Masashi Ebinuma in the final.

The bronze medals in the category were claimed by Arthur Margelidon of Canada and Hungary's Frigyes Szabo following their wins over Italy's Giovanni Esposito and Odbayar Ganbaatar of Mongolia respectively.

Russian Alan Khubetsov also denied Japan - who won four gold medals yesterday - further glory as he defeated Kenya Kohara to top the podium in the under-81kg final.

Khubetsov, bronze medallist at the Hohhot Grand Prix earlier this season, ousted Kohara by ippon in golden score after the bout ended level after regulation time.

European champion Sagi Muki of Israel and Robin Pacek of Sweden were the recipients of the bronze medals as they beat Belgium's Sami Chouchi and Dutch judoka Frank De Wit respectively.

Japan claimed the two gold medals on offer in the women's categories thanks to Aimi Nouchi and Saki Niizoe.

Nouchi triumphed at under-63kg as she proved too strong for European Games winner Martyna Trajdos of Germany to win her third IJF title of the season.

Agata Ozdoba-Blach of Poland and Andreja Leski of Slovenia each clinched bronze following their wins over Sanne Vermeer of The Netherlands and Canada's Stefanie Tremblay respectively.

Niizoe's victory against Sanne Van Dijke of The Netherlands in the final of the under-70kg division saw the Japanese athlete strike gold for the first time at an IJF Grand Prix.

Kelita Zupancic of Canada and Britain's Sally Conway won bronze.

The event in Budapest is due to conclude tomorrow.
