Chefs Using KIREAJI: Osamu Nishida
-
For sushi chefs, the knife is far more than a tool — it is an essential part of their craft, shaping flavor, texture, and presentation in every slice.
Among the chefs who embody this philosophy is Osamu Nishida, a master sushi chef and dedicated educator who uses KIREAJI knives to express the true character of his cuisine. -
-
A Career Forged in Excellence
Nishida has served as head sushi chef at some of Japan’s respected establishments, including Futaba Sushi, Tokyo Bay Hotel Tokyu’s Manyo “Mai,” the sushi counter at the Foreign Correspondents’ Club of Japan, and Hotel Metropolitan Edmont’s “Umihiko.”
His experience across luxury hotels and high-end sushi restaurants reflects not only deep technical skill, but also a refined sense of hospitality and craftsmanship — the ability to transform tradition into memorable dining experiences.
-
Philosophy & Way of Life
Nishida’s philosophy centers on the belief that growth comes through dedication, repetition, and continuous effort.
As an official instructor at the Tokyo Sushi Academy, he teaches aspiring chefs not only technical skills, but also the mindset required for lifelong improvement.
For Nishida, sushi-making is not simply about mastering technique. It is also about developing discipline, character, and respect for both ingredients and tools.

Why He Chooses KIREAJI Knives
KIREAJI knives play an important role in Nishida’s daily work because they provide:
- Smooth, precise cutting performance that preserves delicate textures and natural flavor
- Clean cuts that reduce damage to fish fibers, helping maintain clarity of taste and presentation
- Balance and control that support consistency during long hours of preparation
According to Nishida, a knife should work naturally with the chef’s movements and allow ingredients to be treated with precision and care.
For him, KIREAJI knives are trusted partners that support the refinement of his craft.

Where You Train Shapes Who You Become: Choosing the Right Kitchen for Your Career

The Two Paths in Japanese Professional Culinary Training — And How to Know Which One Is Yours
Every serious cook eventually faces a version of the same question: where should I train? Which kitchen, which mentor, which environment will give me what I need to become the cook I want to be?
In Japanese professional culinary culture, this question has a structure that makes it easier to think through clearly. The training environments available to a young cook divide into two broad categories — large establishments and small ones — and each offers a genuinely different version of the professional education. Neither is universally better. But one is almost certainly better for you, based on who you are and where you want to go.
Understanding the difference, honestly and specifically, is the starting point for making a choice you will not regret.

The Large Establishment: Structure, Scale, and the Discipline of Repetition
Large restaurants, hotel kitchens, major ryokan, and restaurant groups — kitchens of a hundred seats or more — operate according to a logic of division and specialization. The kitchen is organized into stations and sections. Each cook has a defined role. The work of the kitchen is distributed across a hierarchy of responsibilities, from the head chef who commands the whole to the young cook who may spend months on a single preparation.
This structure is sometimes described by outsiders as limiting, and in a narrow sense it is. The young cook at a large establishment does not immediately stand next to the head chef and observe everything. They do not rotate through all sections in the first year. They learn one thing at a time, in depth, before moving to the next.
But this is also the structure's greatest strength. The repetition that large-scale cooking demands is one of the most effective training environments that exists for foundational technical skill. A cook who has peeled a hundred small taro roots in a day, every day, for weeks, has developed a physical fluency with that task that cannot be acquired any other way. The hand knows what to do before the mind has processed the decision. The technique is not performed — it is inhabited.
The camaraderie of a large kitchen is another real advantage that deserves honest recognition. When you train alongside other young cooks at the same stage of their development, you have people to learn from, to compete with, and to be encouraged by. The cook who trains in isolation develops differently from the cook who trains in community. Neither development is wrong, but they are different, and the communal pressure of peers who are also pushing themselves is a form of motivation that is difficult to replicate alone.
For the cook who learns best through structured progression, who finds deep satisfaction in mastering one thing completely before moving to the next, and who wants the community of contemporaries who are on the same journey — the large establishment is the right environment.
-
The Small Establishment: Breadth, Proximity, and the Education of the Whole Kitchen
Small restaurants — individually-owned dining establishments, intimate kaiseki restaurants, kappo restaurants run by an owner-chef with a small team — operate according to a completely different logic.
In a kitchen of four or five people, everyone does everything. The young cook works in immediate proximity to the head chef, observing decisions as they are made, receiving instruction that is direct and personal rather than filtered through a hierarchy. Tasks that at a large establishment might take years to reach are assigned early, because there is no one else to assign them to. The education is comprehensive by necessity rather than by design.
This proximity to the head chef is the small establishment's most significant advantage — and it is genuinely significant. To watch a skilled chef work at close range, every day, is an education that no curriculum can replicate. The decisions they make — about seasoning, about timing, about how to read an ingredient, about when a dish is finished — are visible in real time. The young cook who is present for these decisions, who can ask questions and receive answers in the moment, develops a way of seeing the kitchen that builds faster than the structured progression of a large establishment allows.
The small establishment also teaches the business of cooking, which the large establishment rarely does in the early years. A cook who works in a small restaurant learns how a kitchen runs as a business: how orders are placed, how costs are managed, how customers are attracted, how a dining room is operated. For the cook whose ultimate goal is to open their own place, this education is not supplementary — it is the point. The skills that allow a restaurant to exist and sustain itself are distinct from the skills that allow excellent food to be produced, and a cook who has never seen those operational skills practiced has a significant gap in their preparation for independence.
For the cook who is self-motivated, who learns through observation and independent practice rather than through structured instruction, who wants to see the whole picture of a professional kitchen as quickly as possible, and whose goal is eventual independence — the small establishment is the right environment.

The Real Trade-Offs
Honesty requires acknowledging what each path costs, not just what it offers.
The large establishment, for all its advantages in repetition and community, moves slowly. A cook who trains there will spend considerable time far from the head chef, learning sections of the kitchen that feel remote from the cooking they came to do. The patience required is real, and not every cook has it. The cook who is impatient with structure and repetition, who wants breadth immediately, will find the large establishment frustrating in ways that may outweigh its advantages.
The small establishment, for all its advantages in proximity and breadth, can be isolating. There is no cohort of contemporaries. There is no one at the same stage of development to learn alongside, to commiserate with, or to be pushed by. The motivation must come entirely from within. And the volume of ingredients worked — fewer covers means less product — means that the raw repetition of technical tasks that a large establishment provides automatically must be sought out in personal practice outside working hours. The cook who does not practice independently at a small establishment will develop more slowly than the cook who works the line at a large one.
Neither path is easy. They are differently difficult.
-
A Framework for Deciding
Before choosing, consider these questions honestly — not as you wish you were, but as you actually are.
What is your ultimate goal? If you want to be promoted within an organization, to eventually lead a section or command a kitchen within a structure that already exists, the large establishment aligns with that trajectory. If you want to build your own thing — your own restaurant, your own concept, your own way of cooking — the small establishment teaches the skills that independence requires.
How do you learn best? Some cooks thrive with a clear role and the depth that mastering it provides. Others feel confined by a role and learn fastest when they can see and do everything. Neither is a better way to learn. They are different ways to learn, and knowing which one you are is more valuable than any external recommendation.
What motivates you? If the presence of peers who are pushing themselves makes you push yourself harder, the large establishment gives you that community. If you are more motivated by a personal goal that you pursue regardless of what anyone around you is doing, the isolation of a small establishment will not diminish your development.
What are you willing to trade? Every environment asks for something in return for what it offers. The large establishment asks for patience and acceptance of slow progression. The small establishment asks for self-direction and independent practice. Know which cost you can genuinely pay before you commit.
-
The Mindset That Makes Either Path Work
Here is something that the choice of establishment cannot provide, and that no environment can substitute for: the willingness to seek out learning rather than wait for it to arrive.
In a large establishment, the cook who stands at their station and waits for instruction will develop more slowly than the cook who asks questions, volunteers for extra tasks, and pays attention to what is happening in every corner of the kitchen. The structure of the large kitchen provides opportunities. It does not guarantee that those opportunities will be taken.
In a small establishment, the cook who performs their assigned tasks and goes home will develop more slowly than the cook who practices after hours, who asks the head chef to explain every decision, who treats every working day as a source of information to be extracted as completely as possible.
The path you choose matters. But the approach you bring to whichever path you choose matters more. The cook who approaches training with genuine curiosity, who misses no opportunity to observe and to practice, who asks the questions that need to be asked — that cook will develop in any environment.
The right kitchen gives you the best conditions. What you do with those conditions is always up to you.
