Shotaro Nomura: The Sharpener Who Waited Sixty Years to Be Sure
-
He was born in Taiwan, grew up in Miyazaki, and arrived in Sakai as a teenager with a connection to a distant relative and no particular certainty about his future. Sixty years later, he is one of the finest sharpeners alive. The distance between those two points is the story.
There is a version of the craftsman's life that is told cleanly: the early recognition of talent, the decisive commitment to the path, the steady accumulation of mastery, the eventual arrival at a place of settled excellence. It is a satisfying narrative. It is also, for most craftsmen, not quite true.
Shotaro Nomura's version is truer. It involves sixty years of work, repeated thoughts of quitting, the decision to stay not because of certainty but because there seemed to be nothing else — and, eventually, past the age of sixty, the quiet realization that staying had been the right choice.
This is not a failure story. It is the honest shape of a life spent doing something genuinely difficult, told without the editing that makes such lives seem more inevitable than they are.
-
From Taiwan to Miyazaki to Sakai
Nomura was born in Taiwan and raised in Miyazaki Prefecture, on Japan's southern island of Kyushu — a long distance, geographically and culturally, from the centuries-old knife-making traditions of Sakai in Osaka.
He arrived in Sakai as a teenager — seventeen or eighteen years old, accounts vary slightly — not because of a family connection to the craft but because of a relative who had married into a knife shop in the city. The connection was tenuous. The commitment it represented was everything.
This is worth noting because it changes the terms of what followed. Nomura did not grow up surrounded by the forge. He did not inherit the craft the way that craftsmen from knife-making families do — absorbing it through proximity before they are old enough to choose it. He chose it as an outsider, on the basis of a distant family connection and whatever he could perceive, at seventeen, about the kind of work it was.
What he perceived — or decided — was enough to make the journey. What the journey turned out to require was considerably more than perception.
-
The Tokyo University of Knife-Making
Nomura's apprenticeship was with a master named Ino — a craftsman of the Showa era whose workshop carried a reputation within the industry that was described, by those who knew it, as the equivalent of Tokyo University: the most demanding, the most rigorous, the most uncompromising standard available.
The comparison is instructive. Tokyo University is not simply selective. It is selective in a way that shapes the trajectory of everyone who passes through it — that imposes a standard so clearly above the ordinary that the people who emerge from it carry that standard as a permanent reference point. The workshop of a craftsman like Ino does the same thing. The standard is not articulated. It is demonstrated, relentlessly, by someone who embodies it — and absorbed, over years, by the person who stays close enough to keep watching.
What Ino transmitted to Nomura was specific and exacting: the art of jomono — the highest-grade work, the knives made for head chefs and senior culinary professionals, the blades that represent the ceiling of what the tradition can produce rather than its everyday output. And with it, a teaching that Nomura has carried for sixty years: make one excellent knife rather than many ordinary ones.
This is not an instruction about quantity versus quality in the obvious sense. It is a statement about where attention should go — about the choice, made every working day, between the path that produces more and the path that produces better. Nomura chose the path that produces better. He has been choosing it, every day, for six decades.
-
Thirty Steps Where Others Take Three
The technical reality of Nomura's work is expressed most clearly in a single comparison.
A standard sharpening process, as practiced by competent craftsmen working at a normal professional level, involves approximately three distinct stages. This is the process that produces a sharp, functional knife — a knife that meets the standard that most professional kitchens require and that most professional cooks would find satisfactory.
Nomura's process involves four or five stages, with a total step count that can reach thirty.
Every one of those steps is load-bearing. Remove any single step, Nomura says, and the result changes — not catastrophically, not in a way that would be immediately apparent to the untrained eye, but in a way that he can see and that the professional cook who eventually uses the knife will eventually feel. The accumulation of thirty steps is not procedural excess. It is the accumulated understanding of a craftsman who has spent sixty years learning exactly what each step contributes — and who is therefore unwilling to omit any of them.
This is what the teaching about jomono looks like in practice. Not the dramatic gesture of exceptional dedication, but the daily discipline of not cutting corners when cutting corners would be easier and faster and, to most observers, indistinguishable from not cutting them.
The indistinguishability is the point. The professional cook who uses a Nomura-sharpened knife does not count the steps. They feel the result.
-
Thirty Stones
Nomura works with more than thirty whetstones — natural and synthetic, each selected for the specific contribution it makes to specific stages of the process.
This is not accumulation for its own sake. Each stone in the collection addresses a particular requirement: a particular grit, a particular abrasive character, a particular finishing quality that another stone cannot replicate. The natural stones among them — increasingly rare, increasingly valuable, irreplaceable in the sense that when they are gone they cannot be replaced with equivalent material — are used with the care appropriate to objects whose scarcity is genuine and whose contribution is specific.
The stone collection is a physical record of sixty years of learning — of the discovery, through repeated use and careful observation, that certain stones do certain things better than others, and that the knife sharpened with the right stone at the right stage of the process is measurably different from the knife sharpened with a substitute.
For Nomura, the stone is not an accessory to the technique. It is the technique — half of the system that produces the result. The craftsman who understands the stones understands the sharpening. The craftsman who uses whatever is available produces whatever it produces.
-
The Mirror Finish and the Honkyaki
Among the specific technical achievements that define Nomura's reputation, two stand apart.
The first is honkyaki sharpening — the finishing of single-steel, full-hardness blades that represent the most demanding substrate for the sharpener's art. A honkyaki blade, because it is made from a single piece of steel hardened throughout, has no soft iron cladding to provide tactile feedback during sharpening. The sharpener works on a surface that is uniformly hard, uniformly resistant, and uniformly unforgiving of errors in angle, pressure, or progression. The edge that results from skilled honkyaki sharpening is among the finest that a Japanese blade can carry. The edge that results from incompetent honkyaki sharpening is a ruined blade.
The second is kyomen shiage — the mirror finish, the polishing of a blade surface to a reflective quality that reveals, in the blade's own reflection, every scratch, every inconsistency, every departure from perfect flatness. The mirror finish is simultaneously aesthetic and functional: the blade that reflects light evenly has been finished to a surface consistency that affects the release of the blade from the ingredient and, by extension, the quality of the cut.
Achieving a mirror finish requires the patient sequential work of multiple stones across multiple stages — the same thirty-step process that defines Nomura's overall approach, applied to the task of making a piece of steel reflect like glass. It is slow work. It is work that cannot be hurried without degrading the result. It is the work of someone who has decided, at some point, that the result is worth the time it requires.
-
The Sixty Years It Took to Be Sure
Here is the part of Nomura's story that is most unusual — and, perhaps for that reason, most honest.
He has said that during his training years, the life was hard and the thought of quitting was frequent. Not occasional. Frequent. The work was difficult, the conditions were demanding, and there was nothing about the early years that made the path seem clearly worth continuing.
What kept him was not conviction. It was the absence of an alternative. I have nothing else I can do — this is the reason he gives for staying. Not passion, not certainty, not the romantic sense of vocation that the craft narrative usually requires. The pragmatic decision of someone who had committed to a path and found, when the commitment became difficult, that the alternative was worse.
This is an unusually honest account of how craft lives are actually maintained — not through sustained inspiration but through the more durable substrate of having no better option and therefore making the option you have work.
And then, past sixty — after decades of work, after the recognition and the awards, after the technique had been refined to the level at which it now operates — Nomura says he finally felt it. The sense that the work had been worth doing. Not the certainty that he had chosen correctly, which had been absent for most of the journey, but the retrospective recognition that the choice had produced something real.
This is a different kind of reward from the one usually described. It is not the satisfaction of mastery achieved or recognition received. It is something quieter: the sense, arriving late, that the life spent doing this work had been a life well spent — not because it was glamorous or certain or financially comfortable, but because the work was genuinely good and genuinely worth doing.
Nomura waited sixty years for this. He says it arrived.
-
The Door Left Open
Nomura has no direct successor. He has no son to whom the sixty years of accumulated technique can be passed in the direct lineage that the tradition has always relied on.
This is a loss. There is no way to describe it otherwise. The knowledge in Nomura's hands — the thirty stones, the thirty steps, the understanding of honkyaki sharpening and mirror finishing built across six decades — is the kind of knowledge that does not survive in books or videos or any form of documentation. It survives in proximity. It survives in the relationship between a master who knows and a student who wants to know and is willing to stay close long enough for the knowing to transfer.
Nomura has left the door open. He has said that anyone who comes to learn — anyone willing to do what the learning requires — is welcome, including someone who might eventually surpass him. This is not a modest statement. It is a generous one: the acknowledgment that the tradition matters more than the individual craftsman's position within it, and that the measure of a teacher is not whether the student eventually equals the master but whether the tradition continues.
The door is open. What is required to walk through it is the same thing that was required of Nomura himself: the willingness to stay when staying is difficult, and the patience to wait for the work to become something you are glad you did.
Shotaro Nomura took sixty years to be sure he had made the right choice. The sharpened knives he left behind suggest the choice was correct. The door he left open suggests he hopes someone else will find the same.

The Soul of Craftsmanship
-
Purity is the Driving Force Behind Mastery
For us artisans, “purity” represents sincere dedication—to the materials, to the techniques, and to the craft itself. It is never about being flashy or loud. Instead, it is about facing the steel before us, shaping it, polishing it, and perfecting it. Through this repetitive process, we discover both joy and wisdom.
-
Times may change, and technology may advance, but the artisan’s pure curiosity and determination remain constant. This unwavering spirit is what allows us to keep moving forward, step by step, without compromise.
-
Even in the smallest blade of a handcrafted knife, we envision the moment when someone holds it and feels, “This is the one.” That moment of recognition is both our pride and our greatest joy.
-
Our knives are born with the hope that they will add warmth and color to daily life—whether in the kitchen or beyond. If they can enrich someone’s world, even just a little, then our work has meaning.
-
To master a single thing with pure devotion—that is the essence we hold dear, now and always.
