I used to think that to swim a fast 400m IM, you had to explode like a whirlwind from the first 100m butterfly. Leon Marchand taught me the opposite when he broke the world record with a ferocious front half. But Tomoyuki Matsushita, a 21-year-old Japanese, just gave me another lesson: sometimes, patience is the ultimate weapon.
Hook On September 7, 2026, at the Japanese Intercollegiate Championships, Matsushita touched the wall in 4:05.83 – a new Asian record, placing him in the rare sub-4:06 club alongside Marchand, Phelps, Lochte, and Kalisz. But what caught my attention was not the final time, but how he got there. The front half (1:59.70) was slower than his own swim at Pan Pacs a month earlier, but the back half (2:06.13) was the third fastest in history. The final 50m freestyle split of 27.40 seconds – faster than anyone who has ever swum under 4:06. This is not a random performance; it is a tactical statement.
Context Matsushita entered the 2026 season with an Olympic bronze medal from Paris. He had won both the 200m and 400m IM at the Pan Pacific Championships in August, with a time of 4:06.75. Just one month later, at a domestic collegiate meet – where the pressure was much lower – he improved by nearly a second. This shows an athlete at peak form, but more importantly, he was testing a new tactic: conserving energy in the first two strokes to explode in the last two. In the context of Asian swimming, where athletes like Seto and Hagino once dominated, Matsushita is rewriting the narrative of how an IM swimmer should pace.
Core Look at the specific splits. 100m butterfly: 55.96 – a safe number, not chasing Marchand (who often opens in 54). 100m backstroke: 1:03.74 – also not too fast. But then the 100m breaststroke: 1:09.66, with both 50m splits under 35 seconds. And the 100m freestyle: 56.47, with the final 50m in 27.40 – a speed that even freestyle specialists would envy. The result is a back half of 2:06.13, second only to Marchand (2:05.71 at Olympics) and Phelps (2:05.94 in Beijing 2026). Notably, Matsushita swam a negative split (back half faster than front half) by a whopping 6.43 seconds – a rare margin at this distance. Some records are not born from strength, but from how we distribute energy.
Data analysis shows Matsushita improved by 0.92 seconds in just one month. Physiologically, this is entirely feasible when he adjusts tactics and maintains training volume. But the question arises: is the 'patient' front-half approach the optimal path to approach the world record of 4:02.95 by Marchand? Marchand swims an aggressive front half (often under 1:58 for the first 200m), but Matsushita chooses the opposite. This shows that each athlete has a unique 'formula' based on muscle strength and lactate tolerance. Matsushita possesses a very strong sprint kick (evidenced by his 56.47 freestyle), so saving energy for the back half is logical.
Contrarian But I want to offer a reverse perspective: could this patience be a sign of a hidden weakness? If Matsushita cannot improve his butterfly and backstroke, he will forever be a chaser. Marchand can open in 54 seconds on butterfly and still finish strong. Matsushita, at 55.96, is losing 2 seconds from the start. If he wants to break the world record, he must find a way to increase front-half speed without compromising the back half. That is a difficult puzzle, but not impossible. Look at how Phelps did it: he swam all four strokes evenly, without a huge negative split. I used to think I was right about aggressive tactics. Matsushita taught me that the body does not need my agreement.
Takeaway Matsushita is not just the fourth fastest swimmer in history; he is a living experiment in how tactics can compensate for a lack of absolute strength. With the Asian Games coming up this month, he is the top favorite for gold. And if he continues to improve his front half, Marchand may have to look over his shoulder. The question is not whether Matsushita can break the world record, but when he will test a new tactic – and whether it will succeed.
For Vietnamese swimming, this is a valuable lesson. We often focus too much on training volume and forget about pacing tactics. An athlete like Nguyễn Huy Hoàng, with good physical foundation, could apply similar thinking to the 1500m freestyle. Swimming is not just about who is stronger, but who is smarter at managing energy. Matsushita has proven that.
