Nao Kodaira won her 32nd straight women's 500-meter race on Friday, while Tatsuya Shinhama won his first speedskating World Cup competition over the same distance as Japan won three gold medals on Friday.
The 22-year-old Shinhama joined a quartet of Pyeongchang Olympic champions on the podium's top step as Japan took three of the gold medals on offer on the opening day of the meet on an outdoor oval, with one second-place finish and a third.
Shinhama, competing in just his third World Cup race, earned the first victory by a Japanese man on the World Cup circuit since December 2013, when Keiichiro Nagashima won over 500 meters.
