The 2025 Japan Open concluded tonight from the Tokyo Aquatics Center but not before Olympic silver medalist Tomoyuki Matsushita ripped a new lifetime best in the men’s 200m IM.
After claiming the 4th seed with a solid morning effort of 1:58.78, 20-year-old Matsushita crushed a monster performance of 1:55.60 to take the gold.
16-year-old World Junior record holder in the 400m IM Yumeki Kojima reaped silver with a time of 1:57.51 and So Ogata rounded out the podium this evening in 1:57.64.
As for Matsushita, his swim hacked well over half a second off his previous best-ever performance of 1:56.35. That slower outing was performed at the Japanese World Championship Trials this past March to check him in as Japan’s 4th-swiftest performer in history.
Tonight, however, splitting 24.64/29.03/34.04/27.89, Matsuhita bumps himself up to now rank 3rd among all-time Japanese men and takes over the #1 spot in the season’s world rankings, dethroning teammate Kosuke Makino.
He is also now the 15th-best performer in history worldwide.

Matsushita’s 1:55.60 performance would have garnered him the bronze at the 2024 Olympic Games and 4th place at this year’s World Championships.
It’s important to note that Kojima’s silver medal-worthy 1:57.51 effort represents a near-lifetime best, falling just shy of the 1:57.32 nabbed at this year’s World Junior Championships. That stands as the fastest mark ever recorded by a 16-year-old.
Matsushita’s 200m IM result comes on the heels of last night’s 4:07.67 stunner at the hands of 19-year-old Asaki Nishikawa in the men’s 400m IM. Nishikawa was indeed in tonight’s 2IM final, posting 1:57.80 for 5th place.
