Yusei Imaizumi Sets World Junior Record in SCM 100m Breaststroke

Yusei Imaizumi, a 17-year-old Japanese swimmer, broke the world junior record in the men's short course 100m breaststroke with a time of 56.35 seconds. The record was set at the 2026 Niigata Prefecture High School Autumn Prefectural Tournament. He improved by 0.30 seconds from the previous record held by Shin Ohashi, using a front-loaded pacing strategy, leading the first half faster and maintaining in the second half. Technical analysis shows Imaizumi swam out quickly from the start, maintained rhythm, and turn efficiency in short course was decisive. Although the record was set at a low-tier domestic meet, it shows the strong development of Japan's swimming system. However, the risk of transferring from short to long course still exists, and the intense rivalry with Ohashi. When swimmers enter the short pool, the race begins to tell a different story. I learned to read breathing and swimming rhythm from the signs of the opponent behind. Behind the numbers are young athletes who refuse to stop. A signature not noisy, but can rewrite an entire Japanese swimming ecosystem. Based on my experience watching matches, Yusei Imaizumi has shown clear progress.
