There is a fourteen-page folder on my desk in Osaka. The first page carries the name Ren Kato, fourteen years old, one metre seventy-eight, left-footed. Page nine records twelve separate occasions when he drifted into a space nobody in the stand noticed. The last page carries my signature and a single line: recommend entry to the academy.

That winter I checked the internal archive. The field reserved for technical assessment displayed exactly four words: no information available.

Those words sat on the screen while the paper copy, browned at the edges, sat in my drawer. Since then I have seen those four words more and more often in my trade. And every time I see them, I think of some young athlete standing at the edge of a court, waiting for somebody to open their file.

People dig for gems beneath the earth. I dig for them beneath people. But before anyone can dig, somebody has to write down what they saw.

This is a story about writing things down. And about not writing them down.

Context: a trade built on paper, run on data

Over the past two decades, scouting and youth development in Japan has moved from notebooks into software. J.League academy systems, prefectural table tennis training centres, Japan Table Tennis Association development programmes — all of them now run on player-record platforms. Every young athlete gets an ID, a page, a timeline recording matches, minutes, injuries, sessions.

The concept is elegant. The problem lies elsewhere.

Table tennis has an odd quality: the data that matters most is the hardest to record. A backhand loop at a decisive moment, a short adjustment step to recover balance after a counter-topspin — these do not fit neatly into a field. They live in the eye of the person sitting at the edge of the court, head down, writing.

In January 2026 the International Table Tennis Federation began publishing world rankings weekly rather than monthly. A technical change, but culturally significant: data became denser, more current, and consequently easier to mistake for completeness.

In March 2026 World Table Tennis launched as the ITTF's commercial arm, restructuring the event calendar and the points system. Table tennis moved from a World Tour chain to a tiered pyramid. For young athletes this made the pathway cleaner on paper.

But paper does not play.

What I have observed across the years is this: the more data a system holds, the harder the gaps become to see. People stop noticing the empty space, because it is surrounded by full boxes.

The core: the journey of one report and three leakage points

A scouting report travels through four stages: observation, note-taking, data entry, decision. Four stages. Simple enough. Yet I have counted three leakage points where information disappears en route.

Leak one: the observation stage is not treated as data.

The person at the edge of the court records things that have no corresponding column in the form. A fifteen-year-old walks on with cheap shoes, the sole worn unevenly — meaning he loads his left foot more, meaning his rotation to the right has a long-established habit. There is no box for this. It sits in the margin, handwritten, small. When the report is entered into the system, the margin does not travel with it.

Saitama mud does not cling to shoes; it clings to memory. But memory is not a database field.

Leak two: data entry is performed by people without domain expertise.

In most Japanese academies, record entry is handled by administrative staff. They receive the paper, read it, and select a value from a dropdown. The system does not permit a sentence. It permits a choice: strong, adequate, average, monitor.

A fourteen-page report can become a single line of a few letters: adequate.

Or, where the file is not processed within the cycle, it becomes: no information available.

Leak three: decisions are made on data that is already incomplete.

The decision-maker looks at the screen. The screen shows an empty line. And that empty line is read the same way every other empty line is read: this player has nothing outstanding.

Nobody writes that sentence. It is simply understood.

These three leaks are not technical faults. They are the consequence of an assumption: that whatever matters will always have a box.

In table tennis specifically: the things systems do not count

In youth table tennis there is a gap between what is scored and what decides a career.

The ranking machinery records match results. A fourteen-year-old who wins seven of ten qualifying matches in the prefecture generates a clean data line. But that line cannot explain why he won the ninth. The ninth was the one where he went three games down and came back. The data says: won 3–2. It does not say: in the fourth game, at 11–9 down, he changed his service rhythm.

That change of rhythm is a signal of something rarer than technique: the ability to read a match under pressure. It happened once, in one game, in one tournament, at an event nobody filmed.

Every generation of players is a stratum; I brush away the dust of time to read their youth. But a stratum nobody describes may as well not exist.

This is why I always record touches rather than only scores. Across nine matches of Ren Kato at the Saitama prefectural schools tournament in 2026, I logged more than one hundred and twenty ball involvements. That number exists in no ranking table. It exists in my notebook, alongside dates, opponents, and the weather of each afternoon.

People have asked why I bother recording the weather. Because a wet pitch changes the footfall, and if I do not write it down, three years later I will believe I saw something that was actually the rain.

That is the discipline of a person paid to record: write the apparently irrelevant, so that later you know where you were wrong.

On esports: a shorter pathway and a wider gap

I also follow esports, and the paradox there is sharper than in table tennis.

An esports professional's career is shorter than a footballer's or a table tennis player's. In some titles, peak performance arrives at eighteen or twenty and ends before thirty. Yet the youth development infrastructure of the industry is far younger than that of traditional sport.

My point is not that esports players lack talent or prize money. It concerns the record-keeping behind them.

A fifteen-year-old table tennis player inside a federation system acquires a medical file, a physical-condition file, a competition calendar, and a named person responsible for monitoring. A fifteen-year-old esports player in a private academy typically has: a competitive account, in-game statistics, and a contract.

When the career ends at twenty-five, the file ends with it. There is no next stratum to read.

This is what I want on the record, even if few wish to read it: a system that records only competitive results cannot protect the human being who produced them.

What happened to Ren Kato — and to those four words

In May 2026, preparing to travel to Russia as a tactical consultant for a Japanese broadcaster, I received word that Ren Kato had torn knee ligaments in an academy session. He was fifteen. He cried on the phone. I listened in silence for twenty minutes.

I left the office and spoke to nobody for three days. I walked along the Yodo River in Osaka, morning to night, counting the boats.

I decided to fly back to Tokyo rather than straight to Russia, so I could sit beside him in the operating room. It cost me the first two national-team friendlies in Salzburg.

The quietest moment of my career is the sound of a phone that never rings back.

Years later, recovered, Ren Kato kept playing. He did not become a name anyone would write on a board. He plays in a league I still attend, sitting in the fourth row, taking notes.

His record in the system still displays the same four words.

I tell this story not to make a point about injustice, but because it shows something very specific about how scouting systems operate: a file that is never entered into the system has, in the system's own language, never existed — regardless of what anyone saw on the court.

And when the system says a person never existed, nobody is accountable for having overlooked them. This is the most dangerous part, and it does not lie in the technology. It lies in the transfer of responsibility from a human being to an empty data field.

The counter-intuitive angle: more dashboards do not mean less risk

There is a habit I see repeated across youth academies.

When a missed player is discovered, coaching staff usually conclude the problem was insufficient data. The remedy is more metrics, more forms, more dashboards. But in most cases I have followed, the problem runs the other way: there are too many fields, and consequently the silence of an empty field is misread.

When a dashboard shows a full set of indicators for a player, the reader feels every dimension has been assessed. The absence of a warning flag is taken to mean there is no problem. In risk assessment this is the most serious and most common error: the absence of a recorded signal is read as the absence of risk, when in truth it may simply mean nobody recorded anything.

In Ren Kato's file there were no warning flags. No physical-injury marker, no psychological note. The four words sat exactly where a red flag should have been.

The fix is not an additional metric. It is a very simple technical rule: the system must distinguish between assessed and no data available for assessment. Those two states must display differently. If they display identically, every conclusion drawn from them is unreliable — including the ones that sound most confident.

I once read an internal summary from a training centre in which an entire generation of players was analysed on top of blank fields. The document was long. It had tables, numbers, conclusions. Not one player in it was described in a single sentence. I read it to the end and felt I had read something produced to prove the work had been done.

The trap of the trade: formal completeness mistaken for substantive completeness.

A small note on method

One habit I have kept for years: when writing about a young athlete, I always handwrite the first sentence, never on a machine. The first sentence is usually something meaningless to a system: the boy straightens his socks before every serve; the boy does not look up at the stand even though his mother is sitting there; the boy stands still for three seconds before stepping to the table.

These details predict no result. They forecast no medal. But they are the traces of a person, and I believe the numbers that follow only mean something when the trace is present.

A young coach once asked why I did not drop that section to keep the file tidy. I said that if I dropped it, I would no longer know who I was talking about.

That is my entire answer to the problem I am describing here.

A reflection in place of a conclusion

I do not think this will be solved by better software. I think it will be solved by a small change in the question asked.

Faced with an empty record, people ask: what does this player have. The better question is: who had the chance to watch, and what did they write down.

The fourteen-page folder is still on my desk in Osaka. In the top right corner of the first page, in small handwriting, I added one more line on some late evening — perhaps in 2026, perhaps later. That line exists in no system, and will never be entered into one.

It is the only line in the whole folder I am certain is true.

The crowd leaves the stadium but never leaves history. The task of those who stay behind is to copy that history down before morning.
