Hosts Uzbekistan won four gold medals at the International Blind Sports Federation (IBSA) Judo Grand Prix in Tashkent.
The Para-competition was held alongside the International Judo Federation (IJF) Grand Prix in the Uzbek capital following a deal struck between the two governing bodies.
Uchkun Kuranbaev was among the home winners at Humo Arena, defeating Namig Abasli of Azerbaijan with an osae-komi waza in the men's under-66 kilograms final.
In the women's under-57kg gold medal bout the two countries met again with the same result, as Uzbekistan's Parvina Samandarova forced Sevda Valiyeva to tap out.
Davurkhon Karomatov won the third Uzbek gold in the men's under-81kg, beating Ukraine's Dmytro Solovey via ko uchi maki komi in the final.
Nafisa Sheripboeva then beat another Azerbaijan opponent in the women's under-63kg final, coming out on top after overpowering Khanim Huseynova.
"I am proud that the collaboration between IBSA and IJF is becoming stronger," said IBSA sports director Janos Tardos.
"It is not a coincidence that the two Grand Prix this year are combined with the IJF World Judo Tour.
"The IBSA staff is quite small and thanks to the collaboration we have a lot more resources.
"Another benefit is that the staff of the local federation already knows what to do.
"At previous tournaments, we sometimes had to work with staff that was untrained for the event.
"Now, the staff already had the experience of the IJF Grand Prix."
Iran were the only other country to win more than one gold in Tashkent as they took home a pair of titles.
Vahid Nouri threw Georgia's Lasha Kizilashvili with a left uchi mata for men's under-90kg gold and Mohammadreza Kheirollahzadeh collected the men's over-100kg crown as he held down Uzbek Shirin Sharipov for ippon.
Sandrine Aurieres Martinet of France beat Kai Lin Lee of Chinese Taipei via ippon to win women's under-48kg gold while Florin Alexandru Bologa of Romania ousted Uzbek Sherzod Namazov in the men's under-60kg final with a juji gatame.
In the women's under-52kg, Ukraine's Inna Cherniak performed a strong left koshi guruma, followed up by an osae-komi, to beat Canada's Priscilla Gagne to gold.
Shakhban Kurbanov of Russia beat Germany's Nikolai Kornhass via waza-ari to win the men's under-73kg crown and Brazilian Alana Martins denied Uzbekistan another home gold in the women's under-70kg after victory against Valina Aliboeva on shido penalties.
Azerbaijan did taste success as Kanan Abdullakhanli won the men's under-100kg by utilising soto maki komi against Britain's Christopher Skelley.
Italian Carolina Costa won the women's over-70kg by performing uchi mata maki komi and osaekomi waza against Kazakhstan's Zarina Baibatina.
