Seventeen-year-old Kao Miura cruised to his maiden men's junior figure skating world championship Saturday, completing Japan's first sweep of the men's and women's titles since 2010.
Leading after the short program, Miura landed all three of his quad jumps as he also topped the free skate, scoring 179.63 for a 264.74 total in Calgary where 14-year-old Mao Shimada secured the women's gold Friday.

Yuzuru Hanyu and Kanako Murakami won their respective junior world titles for Japan 13 years ago. Miura became the sixth men's junior world champion from Japan and the first since Shoma Uno in 2015.
"I made mistakes but managed to pull things together. It's great to be 'Champion Miura' again," Miura said, referring to his breakthrough win at the Four Continents in February.
"This is not my goal. I hope to raise my level of performance and keep working from next season onward."
Nozomu Yoshioka came third on 217.79 as Japan's number of men's berths for next season's junior world championship rose to three.
Naoki Rossi of Switzerland, whose mother is Japanese, was second on 220.68.
