Kodaira is unbeaten in six World Cups this season, and the winner of the 1,000 on Monday. "I wasn't at my best today, maybe 80 percent of full fitness," Kodaira said. "But I wanted to race against a strong sprinter and it was good preparation (for the 2018 Winter Olympics)." Takuro Oda won the men's 1,000, and Miho Takagi the women's 1,500. The Japanese team of Misaki Oshigiri, Nana Takagi, and Ayano Sato cruised to victory in the women's team pursuit. South Korea was second, and China third.

"The race was quite difficult," said Wu, a two-time world champion in the 500. "The South Koreans gave us pressure over the final two laps and I almost lost my balance in the final lap." Zang Yize of China won the women's 500. Ayuko Ito of Japan was second, and Choi Min-jeong of South Korea third after her compatriot Shim Suk-hee got tangled up on the final lap with Fan Kexin of China and both were disqualified. In cross-country skiing, Japan also won the women's 10-kilometer free through Yuki Kobayashi. Lee Chae-won of South Korea was second, 24.4 seconds back, and Yelena Kolomina of Kazakhstan was third.
