Denis Ten secured Kazakhstan's first International Skating Union (ISU) championship title after sealing victory in the men's individual competition at the Four Continents Championships in Seoul.
Canada's Meagan Duhamel and Eric Radford, meanwhile, took the pairs gold medal in the South Korean capital.
Ten, exactly one year on from winning Olympic bronze at Sochi 2014, began the day as clear leader following his superb short programme on Thursday, and the Kazakh continued his excellent form with an impressive display in the free skate.
Ten, who is of South Korean descent, delighted the crowd as he performed a quadruple toe, a quadruple-triple to combination, triple Axel-double toe and four more triples and included two level-spins in his bid to claim a first ISU title.
His only mistake came on a solo triple Axel, but it had no bearing on the final outcome as he was awarded a personal best score of 191.85 points, taking his overall tally to 289.46.
It proved enough for the 21-year-old to be crowned champion ahead of the United States Joshua Farris, whose excellent free programme saw him rise from fifth to second in the standings, while China's Han Yan took bronze.
"My major goal for this season was to perform well at this competition," said Ten.
"I was just so happy with how I skated, because I can't say I was in top condition today.
"Overall it was a good skate, but honestly I wanted to skate even stronger than that."
In the pairs competition, Duhamel and Radford recovered from a landing error of their side by side triple Lutz to win their second Four Continents title, having been crowned 2013 champions in Osaka.
The duo had led after the short programme and were awarded a level-four for four elements of their free skate to ensure that their errant landing did not play a factor in the final result, accumulating a total of 219.48 points from the two programmes.
"We're especially proud of the throw quad, because we both made a mistake on the triple Lutz and then we have to turn around so quickly to do the hardest element and that took a lot of strength from us," Duhamel said.
"And that it something that I'm extremely proud of.
"I think for the World Championships we want to add more speed and energy to the programme."
Cheng Peng and Hao Zhang of China finished took the silver medal, while their compatriots Qing Pang and Jian Tong won bronze.
Competition draws to a close tomorrow with the conclusion of the ladies individual competition currently led by Japan's Satoko Miyahara, before the exhibition gala.
