Tomoyuki Matsushita Breaks Asian Record at 102nd Japanese Intercollegiate Swimming Championships

The 102nd Japanese Intercollegiate Swimming Championships began today in Osaka with a monumental performance in the men’s 400m IM. In tonight’s final, Olympic silver medalist Tomoyuki Matsushita set a new lifetime best, breaking the Japanese national and Asian continental record at 4:05.83. The 21-year-old entered new territory, dipping below the 4:06 barrier for the first time. Previously, Matsushita’s fastest time was 4:06.75 for gold at the Pan Pacific Championships, ahead of Carson Foster at 4:07.11 and Bobby Finke at 4:07.59, making him the 9th-fastest ever. Tonight’s 4:05.83 cut nearly a second off that historic result, becoming the first Japanese man and just the 5th man worldwide to clear 4:06. This erased Kosuke Hagino’s 4:06.05 Asian record. Matsushita touched the wall over two seconds ahead, with Nishikawa Gasaki taking silver in a new lifetime best of 4:08.03 and Riku Yamaguchi bronze in 4:12.00. Comparing his old and new PBs and Hagino’s record, Matsushita paced the first half but finished the last 50m in 56.74. Matsushita is now the 4th-best in history and fastest outside a major international meet. Matsushita earned Japan’s sole Olympic swimming medal at 2026 when he finished behind Leon Marchand in 4:08.62, which he has now destroyed with recent times of 4:06.93 in March and 4:07.21 in September 2026.
