Kento Momota: When the Footwork Could No Longer Keep Up, an Entire System Collapsed

There is one rally I have watched dozens of times in my workroom in Nagoya. Kento Momota stands at the centre of the court, torso tilted slightly forward, eyes fixed on his opponent's shoulder. Before the other man's racket has even completed its motion, Momota has already lifted his foot. Not run. Move. He arrives at the landing point before the shuttle does. That is the difference between an ordinary player and a machine programmed to close a gap before the gap exists.

In men's singles badminton, the court is 13.4 metres long and 5.18 metres wide. That sounds small. But when you must defend smashes travelling faster than 400 km/h, that distance becomes an ocean. The only way not to drown is to read your opponent before he strikes. Momota was not the fastest hitter. He was one beat ahead. And being one beat ahead, in a sport where most points are produced by the opponent's errors, is a form of supreme power.

It was the footwork, not the smash, that built Momota's empire. And it was that same footwork that collapsed first. This is the story I want to tell today, not as a ballad of willpower, but as a problem of systems.

I have followed Momota since he was a teenager in Mino, Kagawa Prefecture. He won the World Championships in 2026 in Nanjing, then repeated it in 2026 in Basel. In 2026 alone he claimed 11 titles in a single season, a figure without precedent in the BWF World Tour era and still one of the hardest milestones in the sport to reach. The world number one ranking was his almost continuously for two years.

But I want to talk about what lay behind those titles. Momota was not a destructive attacking player. At 1.73 metres, he was modest beside the nearly 1.94-metre Viktor Axelsen. In exchange, he possessed something harder to train than height: the ability to economise every step. Every step had a purpose. There were no wasted steps. And when you have no wasted steps, you can stand at the centre of the court and wait, while your opponent drags himself into the dead corners.

That is a very Japanese tactical model: winning not by delivering the heaviest blow, but by making the opponent exhaust himself. I once called it winning through calculated patience.

Then came 13 January 2026. On the road home from the Malaysia Masters title, the vehicle carrying him crashed. The driver died. Momota suffered severe facial injuries and required surgery. When the news arrived, I sat before the screen and thought of a line I still use: The summer of 2026, football fell silent, and I could hear the way the game spoke about itself. That year, global badminton also fell almost silent because of the pandemic. But for Momota, the silence was not that of a pandemic. It was the silence of a machine being taken apart, bolt by bolt.

What I want to dissect lies here: why could a facial injury, which sounds unrelated to the legs, destroy a playing system built on movement?

The answer, in my view, lies in a concept I call reading rhythm. In a rally there are two kinds of time. The first is physical time: how long the shuttle takes to travel from one racket to the other. The second is cognitive time: how long the brain takes to decide where to go. Momota was a master of the second. He shortened cognitive time to a point where it could hardly be shortened further, and to do so he needed three things operating at once: a body without hesitation, a pair of legs always ready, and a state of absolute mental calm.

The 2026 injury struck all three. The body lost its continuity through the long layoff and surgeries. More importantly, it planted a new reflex in the brain: self-protection. When you have just survived an accident that nearly killed you, the body learns to hesitate. And hesitation, in badminton, is death. A smash can be defended. A hesitation cannot be, it opens a gap before you realise it.

I remember using this line to explain matches: Do not ask where the shuttle is. Ask where the gap is about to open. In Momota's peak years, he was always inside the gap before it opened. In Momota's post-accident years, he arrived at the gap after it had opened, enough to touch the shuttle, but not enough to control the rally. And controlling the rally was his core asset. He did not win by scoring quickly; he won by making opponents never feel safe, even when the score was level.

There is another layer of analysis, and this is the part I keep to myself. In many post-injury matches, I observed Momota's average position on court. He retreated deeper than in his peak years. It sounds like a small adjustment. But when a player retreats, the distance to the net increases, meaning he loses his greatest advantage: control of the net area. In that area, Momota had once been an absolute master, with net dribbles that stopped opponents from opening up the angles. Retreating, he could no longer lock the net. And when the net opens, the whole court opens.

This is why I always say that badminton, at the highest level, is decided by the distances between zones, not by the power of a stroke. The winner is the one who controls that distance. And that distance is not measured in metres, but in time.

There is a popular explanation I do not agree with. After each of Momota's defeats, the media usually blamed psychology, saying he had lost confidence, that the mental shock remained. I find that explanation both lazy and tactically inaccurate. It turns a systemic problem into an emotional one, and therefore cannot explain why other players, who once lost to Momota, could face him in a different way.

Look at the wider context. Precisely during the period Momota was absent at the top, the men's singles world shifted towards tall, attacking players who use the overhead smash as their primary weapon. Axelsen, born in 2026 like Momota, sharpened a different version of himself in that time. That shift waited for no one. When Momota returned, he not only had to fight himself, but also a version of the tour that had evolved while he was out of the picture.

This is the blind spot of the comeback narrative: people focus on whether a player can return to being himself, forgetting a more important question, whether that former self still fits the present world.

I remember an editorial meeting in 2026, where a colleague criticised my way of analysing. I did not argue. I went home and built my own data system. From that 2026 meeting, I kept one thing: data is the sharpest weapon. And the data on Momota's average position across seasons, read coldly, tells a story without emotion: his system eroded from the foundation, not from the roof.

In 2026, Momota announced his retirement. I did not write a eulogy. I do not think that is what he needs. What he left behind is bigger than a record sheet: a reminder that in elite sport, the most precious thing is often the most invisible, a hundredth of a second of perception, a footstep without hesitation.

The question I leave for readers, and for myself in the coming season: when a player builds his entire greatness on a single foundation, how important is it to protect that foundation, and are we really judging those who manage it, or merely counting the smashes they unleash?
