Azerbaijan and Japan each won three gold medals on the final day of the Karate 1-Premier League event in Baku.

Olympic silver medallist Irina Zaretska, Aminagha Guliyev and Asiman Gurbanli provided victories for the host nation at the Heydar Aliyev Sports Hall, while Japan won both kata titles through Kakeru Nishiyama and Hikaru Ono and a kumite gold courtesy of Ayaka Saito.

Zaretska took on Italy's Silvia Semeraro in a thrilling women's kumite under-68 kilograms final which ended 4-4, being settled in the home favourite's favour by a decision.

Guliyev and Gurbanli both faced Egyptian opponents in their gold-medal bouts.

The former triumphed in the men's kumite under-60kg by beating Karime Aboeitta 6-5 in another entertaining final, while the latter edged out Taha Mahmoud 2-1 in the men's kumite over-84kg.

Japan's kumite title was provided by Saito in the women's over-68kg as she overcame Anastasiya Stepashko of Ukraine 4-1 for her maiden Premier League gold.

An all-Japanese men's kata final went the way of Nishiyama, who scored 26.06 to Kazumasa Moto's 25.8, while in the women's kata decider Asian champion Hikaru Ono notched 26.54 to beat the 25.34 effort of Hong Kong's Tokyo 2020 Olympic bronze medallist Grace Lau Mo-sheung.

World champions Ahlam Youssef and Youssef Badawy of Egypt triumphed in the women's kumite under-55kg and men's kumite under-84kg categories.

Youssef's bout against Ukraine's Anzhelika Terliuga was scoreless, with the Egyptian awarded the victory by decision, while Badawy thrashed Japan's Rikito Shimada 8-1.

Olympic and world champion Steven Da Costa of France saw off Greece's Dionysios Xenos 2-0 to take gold in the men's kumite under-67kg.

Rikito Shimada beat Sweden's Anna-Johanna Nilsson 2-0 in the women's kumite under-61kg final, Niurkanat Azhikanov of Kazakhstan took gold in the men's kumite under-75kg by beating Iran's Bahman Asgari Ghoncheh 3-2, and Venezuela's Yorgelis Salazar completed the list of champions with an impressive 5-0 victory over Sara Bahmanyar of Iran in the women's kumite under-50kg.

Baku marked the penultimate Karate 1-Premier League event of the season.

A season-ending leg had been due to take place in Los Angeles from October 7 to 9 after it was moved from Moscow due to the Russian invasion of Ukraine, but the American city is unable to host it as planned due to "unforeseen circumstances".

One more Premier League competition is planned this season, but dates and the venue are still to be announced.
