Japan's Shoma Uno holds a narrow lead at the NHK Trophy after finishing the men's short program in first place Friday despite falling during a combination jump.

The Pyeongchang Olympic Games silver medalist registered a score of 92.49 at Hiroshima Green Arena to finish 1.12 points ahead of Russia's Sergei Voronov, who is aiming to defend the title he won last year in Osaka.

Uno landed his opening jump, a quadruple flip, but fell during a combination after over-rotating on a quadruple toe loop. He landed his final jump, a triple axel, to wild applause from the home crowd.

"Unfortunately it was a big fall. I'll have a look at my short program and see what needs to be changed ahead of the next meet," the 20-year-old Uno said.

Voronov, 31, landed all his jumps -- a quadruple toe loop-triple toe loop combination, a triple lutz and a triple axel. He finished ahead of third-placed countryman Dmitri Aliev, who scored 81.16.

In the women's competition, Japan's Satoko Miyahara and Mai Mihara were in second and third place, respectively, following the short program.

Russia's 2015 world champion Elizaveta Tuktamysheva held the lead with a score of 76.17, just 0.09 point ahead of Miyahara.

The 21-year-old Tuktamysheva -- who took gold at the 2015 Shanghai worlds ahead of Miyahara -- received a standing ovation following her routine that included a triple axel and triple lutz.

Miyahara opened with a triple lutz-triple toe loop combination before landing a double axel and a triple loop en route to a season-best score of 76.08.

"Although I was nervous, I jumped better than I thought I would," the 20-year-old Miyahara said. "I achieved what I was aiming for in the short program. I'm going to try really hard to execute my routine in the free skate."

The last of the 12 competitors to hit the ice, 19-year-old Mihara followed her opening triple lutz-triple toe loop combo with a double axel and a triple flip to score 70.38 in her NHK Trophy debut.

Making her first senior Grand Prix appearance, Japan's Rika Kihira finished fifth with a score of 69.59.

The 16-year-old fell on her opening jump, a triple axel, but skated a clean program the rest of the way, landing a triple flip-triple toe loop combination and a triple lutz.

"I went into the triple axel too fast. I'm glad to have made my Grand Prix debut, but I'm not satisfied with my score," Kihira said.

Among the other Japanese men, Sota Yamamoto came in sixth with a season-best 74.98, while Hiroaki Sato scored 67.38 for 10th place.
