Hosts France picked up two gold medals as the first World Karate Federation Karate-1 Premier League event of the season ended in Paris.
Competing at the Pierre de Coubertin Sports Hall, two of France's three finalists secured victory today in the men's under-67 kilograms and women's under-61kg kumite divisions respectively.
On the men's side Steven Dacosta - who won world gold in Madrid last year - triumphed in his final with a 5-0 win over Italy's 2015 European champion Luca Maresca.
Gwendoline Philippe claimed France's second gold when she upset two-time world champion Giana Lotfy from Egypt.
The Egyptian initially took the lead with an ippon, but Philippe bounced back with a yuko and then scored two waza-aris and another yuko to take the gold 6-3.
That result cemented 19-year-old Philippe as a rising star to be reckoned with.
The only French karateka to lose today was Nancy Garcia, who lost to Japan's Ayumi Uekusa in the women's kumite over-68kg final 7-3.
That was by no means the only gold for Japan, who also won both the men's and women's kata divisions.
Reigning world champion Ryo Kiyuna beat Spain's Damian Quintero in their title deciding bout, while Kiyou Shimizu avenged her World Championship defeat with victory over another Spaniard, Sandra Sanchez.
Whilst it was largely a successful day for Japan, they did lose the women's under-50kg final.
In that bout Turkey's 2018 World Championship silver medallist Serap Özçelik beat Miho Miyahara comfortably 8-0, in what was a repeat of last year's contest for world gold.
Another world champion to lose was Italian Angelo Crescenzo, who fell to a 3-1 defeat against Iran's Majid Hassan Niadeilami in the men's kumite under-60kg final.
World champion Dorota Banaszczyk suffered the same fate in the women's kumite under-55kg contest.
The Pole, who turned 20 today, was beaten by Ukraine's Anzhelika Terliuga 4-0, while five-time world champion Rafael Aghayev from Azerbaijan was beaten by Japan's Ken Nishimura in the men's under-75kg class.
The day's other results saw Switzerland's Elena Quirici win the women's under-68kg class against Japan's Kayo Someya, while Anton Isakau from Belarus won the men's under-84kg final when Iran's Mahdi Gharaizadeh Mahani retired injured.
The same situation occurred in the men's over-84kg final, where another Iranian in Saleh Abazari withdrew against Georgia's Gogita Arkania.
The next Karate-1 Premier League will take place in Dubai from February 15 to 17.
