  • There is a question that is quietly becoming the most important question of our time. Not "what can AI do?" — that question answers itself faster every year. The more urgent question is this: when AI can do almost anything, what will you choose to do yourself, and why?

    The answer, I believe, begins not with productivity frameworks or career strategy. It begins with something far simpler and far older: the feeling of being genuinely moved by something. The Japanese call it tokimeki — a word that resists clean translation, but points toward the particular aliveness you feel in the presence of something that matters to you. The quickening. The spark.

    In the age of AI, tokimeki is not a luxury. It is the compass.

  • What Amazon Understood That Most Companies Haven't

    When Amazon began integrating the KonMari method into its operational processes — asking its people, in the middle of a vast efficiency machine, to identify which parts of their work sparked joy — something interesting was being admitted.

    The company was not being sentimental. It was being practical. When the question becomes "which of these tasks should a human do and which should a machine do," the purely logical approach gets stuck quickly. Everyone has reasons to hold on to their work. Everyone can argue for their own indispensability. The conversation goes nowhere.

    But when you change the question — when you ask not "should this be automated?" but "does this spark something in you?" — the conversation opens. People can answer honestly. They can let go of tasks they were performing out of habit rather than meaning. And they can identify, with surprising clarity, the work that matters to them in a way that a machine optimizing for output cannot replicate.

    The line between human and AI work is not drawn where logic ends. It is drawn where the spark begins.

    This is the insight that will define how the most thoughtful people navigate the next decade. Not resistance to AI. Not uncritical adoption. But the disciplined practice of knowing what lights you up — and letting that knowledge guide everything else.

  • What AI Cannot Feel in Its Body

    Here is what large language models cannot do, regardless of how capable they become: they cannot feel the resistance of a blade against a vegetable. They cannot feel the accumulated fatigue of an hour of practice, or the specific moment when something that was difficult becomes suddenly, bodily natural. They cannot feel the satisfaction of a skill that has moved from the mind into the hands, and then into something deeper than either.

    I spent weeks practicing katsuramuki — the technique of peeling a daikon radish into a single, continuous, unbroken sheet — before the graduation test at my sushi school in Tokyo. I practiced until my hands understood what my mind had been trying to explain to them. And when I finally passed that test, what I felt was not the pride of having achieved a measurable outcome. It was something that had entered my body and would not leave.

    That experience — the practice, the failure, the return, the eventual fluency — is entirely outside what AI can access. Not because AI isn't intelligent. But because intelligence without a body, without sensation, without the experience of wanting something and working toward it and feeling the difference when you arrive — that intelligence has no access to what the wanting felt like, or why it mattered.

    The people whose work will remain most distinctly human in an AI world are not the ones who compete with AI on its own terms. They are the ones who bring something to their work that AI structurally cannot — the record of a life lived with genuine feeling.

  • The Request Is Everything

    There is a useful way to think about the relationship between human and AI that comes from an unlikely source: the Japanese manga character Doraemon.

    Doraemon is a robot from the future who can produce almost any tool or solution from his pocket. He is, in a sense, a perfect AI assistant — capable, resourceful, technically superior to the humans around him. But the story is not about Doraemon. It is about Nobita, the boy who asks. The whole mechanism depends on someone having a desire — specific, personal, sometimes logically unjustifiable — and making a request.

    Without the request, nothing happens. Doraemon sits there with the pocket full of solutions to problems that no one has thought to name yet.

    This is the condition we are moving into. AI has the pocket. What it doesn't have is the wanting. It cannot generate the desire to make butter from air, or to peel a radish in one continuous sheet, or to carry a six-hundred-year knife-making tradition from one culture to another across an ocean. These desires come from somewhere that AI cannot reach — from bodies that have felt things, from histories that have accumulated meaning, from the specific spark that a specific person feels toward a specific idea.

    The person who knows what they want — who has cultivated the clarity to identify their own tokimeki and the confidence to act on it — holds the most powerful position in an AI world. Not because they can outcompute the machine, but because they can direct it toward ends that matter.

  • Objects That Spark Something

    This brings me to what I believe is an underappreciated dimension of the question: the role of the tools and objects that surround us.

    If tokimeki is the compass, then the objects we choose to keep close either sharpen that compass or dull it. A kitchen full of objects chosen for price or convenience — objects that ask nothing of you, that could be replaced tomorrow without any sense of loss — is a kitchen that quietly trains you to feel less. To expect less. To settle for function without meaning.

    A knife that was made by hands that spent a lifetime learning what good steel requires — a knife that carries in its geometry the answer to six hundred years of asking what a blade should be — is a different kind of object entirely. It is an object that asks something back. It asks attention. It asks care. It asks the particular quality of presence that comes when you are working with something you know is the product of genuine mastery.

    I am not being romantic about this. I am being precise. The knife I use is not the same as a knife I could replace without thought. The difference is felt in every cut — not only in the performance, but in what the performance asks of me. And what it asks is the same thing that katsuramuki asked: that I show up fully, that I feel what is happening, that I bring my body and attention to the work rather than just my hands.

    Objects that spark something in you are not indulgences. In an AI age, they are the physical anchors of your humanity — the daily reminders that you are a creature who feels things, who cares about things, whose engagement with the world is irreducibly personal.

  • What KIREAJI Is Actually For

    When I moved abroad and began this work — carrying Sakai's knife-making tradition to kitchens around the world — I was not thinking about AI. I was thinking about imitations. About the knives I saw in foreign markets that borrowed the language of Japanese craft without any of its substance. About the customers who were buying those knives and not knowing what they were missing.

    But the deeper I go into this work, the more I understand that these two concerns are the same concern expressed in different registers.

    Imitation knives are produced by the same logic that produces undifferentiated AI output — the logic of replication without origin, of form without the specific human history that made the form meaningful. A knife that looks like a Sakai knife but was produced without the hands of a smith who has spent twelve years at a forge, without the hours of a sharpener who has learned to feel what the whetstone requires — that knife is a statement that the human history doesn't matter. That the origin doesn't matter. That what you hold in your hand is just a product like any other.

    KIREAJI exists to say: it is not just a product. The origin matters. The history matters. The specific people matter — the Traditional Craftsman who forged the blade, the sharpener who brought it to its edge, the handle-maker who understood that how the hand meets the knife shapes everything about what the hand can do.

    And it matters not just as heritage. It matters because an object that was made with full human presence — with decades of accumulated feeling, with the specific spark of a craftsperson who chose this work because it lit something in them — is an object that carries that presence forward into every kitchen it enters.

  • The Compass for What Comes Next

    We are moving into a world where the question "can a machine do this?" will increasingly answer itself with yes. The question that will remain — the one that matters more the further we go — is: "does this spark something in you that you would not want a machine to replace?"

    That question is the compass. The people who have done the work of knowing themselves well enough to answer it honestly — who can identify their tokimeki with clarity and act from it with confidence — will navigate the AI age not as people displaced by a technology, but as people who understand what technology is for and what it is not for.

    Surround yourself with objects that spark something. Not because it is sentimental. Because every object you choose carefully is a small act of resistance against the logic that says function is enough, that optimization is the point, that what cannot be measured cannot matter.

    A knife made in Sakai, by hands that have spent a lifetime learning what good cutting requires, cared for and maintained and sharpened over decades of use — that knife is not merely sharp.

    It is a daily reminder of what human attention, sustained over time, can make. And in an age of artificial intelligence, that reminder is worth more than it has ever been.

How We Decide

The Four Principles of KIREAJI
Everything we do is guided by four clear principles. They define what we stand for—and what we will never compromise.

The Four Principles of KIREAJI
  • Understanding Grows Slowly

    When I first heard that our knives were being shared around the world with the hope of fostering understanding between cultures, I felt both humbled and thoughtful.

    As craftsmen, we do not often speak about large themes such as peace or global tension.
    Our work is quiet.
    We face steel each day, shaping it carefully, patiently.

    A knife is made through repetition — hammering, heating, cooling, sharpening.
    It requires concentration and respect.
    If we rush, the blade will not respond as it should.

    Perhaps understanding between people is not so different.

    It cannot be forced.
    It cannot be hurried.
    It is built slowly, through care and steady effort.

    If a knife forged in Sakai travels to another country and is used with respect,
    that alone is meaningful to us.

    We may not change the world in dramatic ways.
    But we can continue our craft with sincerity.

    And if that sincerity travels with the blade,
    then we are grateful.
