Shimizu blazed around the Kirifuri Skate Center in Nikko, in 35.55 seconds for a new rink record. Ryohei Shimizu came in second in 35.93, while Masaaki Kobayashi and Joji Kato were in a tie for third. Both clocked 36.10. In the women's 500, Shihomi Shinya took the lead with a rink record time of 39.16 to move a step closer to claiming her first national sprint crown.

Sayuri Osuga and Tomomi Okazaki followed in second and third with times of 39.42 and 39.63. Due to a sudden rise in temperature at the rink, the competition had to be temporarily interrupted as the ice had started to melt. The two-day event, in which the overall winners in both the 500 and 1,000 meters claim the national sprint titles, also serves as a qualifier for the World Sprint Championships to be held in Nagano in January 2004.
