Japan's Nao Kodaira on Friday won the women's 500- and 1,000-meter races at the speed skating World Cup.

The wins boosted her total World Cup victories to 14, breaking the Japanese women's record of 12 held by Tomomi Okazaki. Kodaira also triumphed in the women's 1,000 in the opening round held in the Netherlands earlier this month.

"Unlike Okazaki-san, who stacked up her wins little by little, I've been able to win a lot in the past two years," Kodaira said. "It's important to keep growing (in numbers). I want to work hard so I can surpass myself."

In the 500, the 31-year-old sprint specialist Kodaira clocked 37.08 seconds, with Marsha Hudey of Canada taking second in 37.87 seconds and Austrian Vanessa Herzog third in 37.96.

Kodaira remains undefeated in the 500 since last season with 19 consecutive wins at home and abroad, including 11 wins in the World Cup.

In the 1,000, she completed her distance in 1 minute, 14.33 seconds, 0.46 second faster than the runner-up, compatriot Miho Takagi. American Heather Bergsma came in third at 1:15.04.
