Shoma Uno edged Vincent Zhou of the United States on Friday to take the lead after the short program at the NHK Trophy, the fourth event of the International Skating Union's Grand Prix series.
Uno opened with a quad flip and then landed a quad toe as part of a planned combination jump but could only manage a double toe instead of a triple toe on the second element.
The Olympic silver medallist also landed a triple axel and finished with 102.58 points.
"That's a jump I know I can do so it's a bit disappointing," the Japanese skater said of the combination jump. "The free skate tomorrow will be twice as hard as the short program so I will have to be at my best."

Skating first in the final group, Zhou landed a quad lutz-triple toe combination as well as a quad salchow and a triple axel for a season-best 99.51 points. The 2019 world bronze medallist is coming off his first Grand Prix title at Skate America, where he upset favourite Nathan Chen.
Zhou's last two jumps were slightly under-rotated.
"Actually, I felt a little bit shaky. My legs were a little bit nervous, and I think that was reflected in the quality of some of my spins and my triple Axel," Zhou said. "I definitely understand why I didn't reach 100 points, but overall I'm pretty happy with my performance. I think it is a good point to move on to tomorrow."
Canada's Nam Nguyen heads into the long in 10th place with 64.28. The Ajax, Ont., skater struggled with his opening elements, doubling his salchow combination and under-rotating his triple axel.

Cha Jun-hwan of South Korea, who opened with a quad salchow, was third with 95.92 points.
Two-time Olympic champion Yuzuru Hanyu was forced to withdraw because of a right ankle injury.
In the women's short program, defending champion Kaori Sakamoto led a 1-2 finish for Japan.
Skating to "Now We Are Free" from "Gladiator," Sakamoto landed a triple lutz, a double axel and a triple flip-triple toe combination to score a season-best 76.56 points.
"I was able to skate cleanly and I was very calm throughout," Sakamoto said. "I was quite nervous and felt like I wasn't well grounded, but during the warmup, I was able to get my usual jumps back and I was able to realize that I was back to my normal self."

Mana Kawabe landed the only triple axel of the women's short program and followed that with a triple lutz-triple toe and a triple flip for a personal-best 73.88 points.
