Japanese snowboarder Ayumu Hirano said he had achieved "one of my childhood dreams" after winning gold at the halfpipe on Friday.
"It hasn't sunk in yet," the 23-year-old said.
After being dissatisfied with his first two runs, he dove into the third and final run, and "I did what I wanted to do right at the end," he said. He had been in silver medal position after the second run, trailing Australia's Scotty James — "but I managed to express my anger well at the end," he said.
"It wasn't nervousness, but I had a different feeling from usual," he added. "I was ready to take the plunge and give all, and it was great to finish it off cleanly."
The gold medalist also competed alongside his younger brother Kaishu Hirano, 19, who finished ninth and pulled off a massive jump meters into the air. "Us brothers making this stage and winning it myself was also great for both of us," Ayumu Hirano said.
He also paid tribute to five-time Olympian Shaun White, who ended his snowboarding career with a fourth-place finish at age 35.
"Shaun's been challenging as he's always been, he's the oldest here and he's always showing me things I can't experience yet," Ayumu said. "He's always been my motivation and I think (Beijing 2022) was a big challenge for him as well."
