Marchand Admits 'Fear' of Japan's Golden Swimming Generation: Who Can Stop the 'IM King' on the Path to Los Angeles 2028?

When Leon Marchand said he is 'truly afraid' of Japan's swimming generation, it was not merely a soundbite from a four-time Olympic gold medalist. It was an echo from a pool in Paris where he had just witnessed age-group records shattered in what he considered his safest territory.

In the summer of 2026, Tomoyuki Matsushita, a 21-year-old from Tsukuba University, stood on the Olympic podium with a silver medal in the 400m Individual Medley. Just months later, at the 2026 World Championships, he repeated that performance. In the same timeframe, 17-year-old Yumeki Kojima from Osaka broke the 400m IM world junior record with a time of 4:07.02. And Shin Ohashi, also 17, topped the rankings in both 100m and 200m breaststroke, with world junior records in both distances.

One week after these three young talents stood atop the podium at the 2026 Asian Games on home soil, Marchand returned to Japan. He did not come to compete. He came to observe.

Background of the Generational Competition

Leon Marchand, 24, currently holds the world record in the 400m IM at 4:02.50. He owns four individual Olympic gold medals — all in IM and breaststroke events. For the past two years, since defeating defending champion Ryan Lochte at Tokyo 2026, he has faced virtually no peer in the 400m IM.

But why would an absolute dominator be worried? The answer lies in the Osaka pool where Ohashi just completed the 200m breaststroke in 2:06.59 — only 0.74 seconds slower than the Olympic record Marchand himself set at Paris 2026. This was not a rookie having one spectacular day. This was a 17-year-old reaching a level almost unbelievable in breaststroke — an event demanding the most intricate technique, where just a small mistake underwater or at the wall can cost precious seconds.

What convinced me — after years of following international swimming competitions — that this was not a passing wave was the structure of results from all three Japanese young talents. Matsushita, 21, has proven his ability to perform at the highest level through two runner-up finishes at the Olympics and World Championships. Kojima, 17, not only has the 400m IM junior record but shows versatility across all strokes — the foundational skill of a world-class IM swimmer. And Ohashi, with junior records in both 100m and 200m breaststroke, is moving forward at a pace even Marchand must respect.

Technical and Statistical Analysis

Let's put the numbers on the scale. In the 400m IM, Marchand stands at world-class level with a record of 4:02.50. The gap between him and Kojima is 4.52 seconds — significant, but not impossible to close within two years, especially when the comparison subject is only 17 and in the fastest physical development phase.

The more notable aspect lies in the 200m breaststroke. The current world record belongs to China's Qin Haiyang at 2:05.48, while the Olympic record belongs to Marchand — 2:05.85. Ohashi, at 17, has reached 2:06.59. This is a gap of 1.11 seconds from the world record and 0.74 seconds from the Olympic record — numbers any swimming coach would say can definitely be erased as a young athlete continues developing.

However, this is also when I need to raise unanswered questions. Junior-level performance and results at major competitions are two completely different worlds. Matsushita has proven he can perform consistently at the highest senior international level through multiple competitions. But Kojima and Ohashi? They have only shone in a few of the biggest competitions. The transition from junior to senior level is usually the real test — where psychological pressure, competition intensity, and fierce competition can slow many young talents down.

Another factor to consider is competition schedule and load. IM and breaststroke are events demanding peak physical fitness and perfect technique. Competing simultaneously in both events — as Ohashi has done with 100m and 200m breaststroke — can create energy conflicts and increase injury risk. For young athletes in physical development phases, this is a fine line between comprehensive development and burnout.

Contrarian Angle

There is a truth the media often overlooks: Marchand is not afraid of Ohashi simply because of the 17-year-old's speed. He is afraid of the system that created that swimmer.

Japan, with its club-and-university model, has built an impressive talent pipeline in breaststroke and IM. While Marchand trains under Bob Bowman — the legendary coach who led Michael Phelps to the top — Japan's young talents are developing in a brutally competitive domestic environment. What does this mean? It means when they step onto the bigger stage, they are already accustomed to competing at high levels.

Matsushita, when asked about his ambitions, declared he would defeat Marchand at Los Angeles 2028. This was not a promise from a dreamy rookie. This was a declaration from an athlete who has twice finished runner-up at the Olympics and knows precisely the gap between himself and the leader.

But this is also when we need to cool expectations. Junior records and performances at Asian Games are not perfect measures for Olympic-level success. Many young talents shone brilliantly at 17 but slowed down during their maturation phase — sometimes due to psychological pressure, sometimes due to physiological changes that development brings.

More importantly, Marchand is still in his prime. At 24, he has at least one or two more Olympics to affirm his position. Experience at major competitions, pace control ability, and competition psychology — these are factors that a young talent, no matter how talented, cannot acquire overnight.

The Road Ahead

When I look back at my own journey — from a Vietnamese boy taking his first dive into a pool to sitting in the commentary room in Los Angeles, watching races that push the boundaries of sport — I realize that what Marchand said is not just about swimming. It is about respect for a system producing athletes capable of competing at the highest level.

Japan's golden swimming generation is not just a challenge for Marchand. They are proof that competition in world swimming is changing — where traditional powerhouses like the USA and Australia must now make room for emerging systems.

Matsushita will be the first to challenge Marchand at the 2027 World Championships. If he can narrow the gap to under 2 seconds, that will be a signal that the competition at Los Angeles 2028 is entirely possible. Kojima needs to continue breaking records and prove he can perform consistently at the senior level. And Ohashi — the talent Marchand mentioned most — needs to overcome the psychological barrier of a much more brutal competition environment than the Asian Games.

The 2026 Asian Games have ended. But the real race has just begun. And I, having spent over a decade watching strokes that shape sports history, will continue to observe — not to find the winner, but to understand that in every competitive moment, there are human stories far beyond the numbers on the scoreboard.

When a goalkeeper steps out of goal, the match begins to tell a different story. And in the pool, when a young talent steps out of the safe zone of youth competitions, the real competition has only just begun.
