Kobo Aizawa: Tools Before Products — Kitchenware from Tsubame Since 1922
The twin cities of Tsubame and Sanjo in Niigata are known across Japan as a center of metalworking — Tsubame alone makes about 95% of the spoons and forks produced in the country. In this town of makers we visited Kobo Aizawa, founded in 1922 and making kitchen tools for generations. We were welcomed by the fifth-generation president, Mr. Aizawa.

In business terms, Kobo Aizawa is a tonya — a producer-wholesaler. Its products are made by partner workshops in the same region, under Kobo Aizawa's planning and standards. Today many brands are launched by the factories themselves, and most of the brands we carry are maker-led. So why does Kobo Aizawa stand out, and why did we want to introduce them? This visit gave us the answer.
Function comes first
Kobo Aizawa's shelves are filled with tools that stay useful whatever the era. Behind each one is the same question: why does this object need to exist? Mr. Aizawa is clear that the first thing to settle when making a product is its function.
"Before it is a product, it is a tool. If you bend the function, it stops being a tool. If you chase good looks or design first, the main reason the tool exists becomes blurred."

That is why development never starts from design or silhouette, and outside designers are generally not brought in. Mr. Aizawa plans every product himself, always starting from why it should be made — from function.

Which material suits the job? How can it be easier to use, easier to hold? Pursuing these questions is what produces the functional, sturdy tools Kobo Aizawa is known for. "Because of that, I don't think the silhouettes are very cool," he says with a laugh.

Yet we are drawn to them precisely because of their functional beauty. What makes something "cool" is hard to define — but to us, Kobo Aizawa's tools are. Perhaps an object with true functional beauty simply becomes beautiful on its own.
Tools that outlast the times
The company was founded in 1922 by Mr. Aizawa's grandfather as a local wholesaler, selling farm tools made in neighboring Sanjo and other everyday goods people needed. Manufacturing began with his uncle, the third generation, who made carpentry tools such as hammers, planes and gimlets. When a customer asked them to make a pot, they began making kitchen tools as well. As power tools took over carpentry, they gradually stopped making carpentry tools and focused on the kitchen.

Tsubame had long been a center of kitchenware, and Kobo Aizawa has now been making cooking tools here for about 50 years. While many shops have disappeared over time, Mr. Aizawa believes they have lasted because they think of their products as tools.
"A tool is a tool in any era. The yukihira pan (a traditional Japanese saucepan with a spout on both sides) has kept the same shape since the Edo period — that shape must simply be the right answer. Since we don't start from design, our tools aren't flashy or colorful. You could call them simple, or plain. Even if you tire of them and chase something cooler, you end up coming back. In the end, these are the ones that are right."

This is Kobo Aizawa at its core. Professionals experiment and hesitate, and arrive back at the same tool — and we get to hold the result of that search in our hands. That alone feels like a luxury.
Never losing sight of the origin
During the pandemic, outdoor activities such as camping boomed, and many makers and trading companies in Tsubame produced outdoor gear. While companies around him rode that wave, Mr. Aizawa chose not to.

"It did look attractive. But then I ask myself: if we do this, what comes next? Why are we doing this at all? If you want to grow the company, there are ways to do it. But I'm happy with our current size — what I really want is to make things I'm satisfied with."
He does not reject following trends, but if you ride one, you have to keep riding. "At least, I don't have that talent," he says. Knowing himself well and never losing sight of the company's purpose — through every rise and fall of fashion — is what keeps Kobo Aizawa making tools that last.

No compromise in any step
Quality is another of Kobo Aizawa's strengths. The world is full of cheap kitchen tools, but they refuse to compromise on making tools they can stand behind.

Even a single spoon involves more than twice as many steps as the six shown in the photo. Steps could be skipped and materials downgraded, but leaving out even one would noticeably lower the quality. "You could skip four or five polishing steps alone if you just wanted to make it cheaply," Mr. Aizawa says. "But the question is how to make it a better tool. It's not about the price."

For cutlery, for example, barrel polishing — tumbling the pieces in a drum with stone-like media — can be done once or many times, and the finish is completely different. You can skip it, but you don't: that is the key. His greatest wish is for his tools to be passed from parent to child and used for a lifetime.
When cheap alternatives are everywhere, why choose this tool? Asking "would I want my children to use this one day?" may be a good way to choose — and behind every tool worth passing on, there is always a dedicated maker.
At the workshop: the craftsman's touch
Tsubame is a town built on division of labor. Kobo Aizawa has no factory of its own; it works with local partner workshops and craftspeople across Japan who share its philosophy. Metal and stainless steel are made in Tsubame, with Kobo Aizawa covering the cost of the molds. Bamboo pieces are made in Beppu, Oita, famous for bamboo craft, and lacquerware in Katayamazu, Ishikawa. Working with the regions that know each material best lets them make a wide range of tools.

We were shown around a Tsubame factory that makes stainless steel pots and tumblers.

Craftspeople work at the machines carefully, by hand. Tasks that look simple rely on a craftsman's fine sense of touch and small tricks of the trade — which is how the quality is maintained.

Take the handle of a pot. Before it is bent by machine, each one is coated with oil by hand, so the metal can be bent without being scratched.


These are the parts that will become lids. The craftsman instantly reads the grain of the metal, invisible to an amateur, and polishes along it to bring out the shine.


This is only the first polish. It already looks beautiful, but a second polish follows, and depending on the metal, even more steps may be added.
Here, the handle is being attached to a kettle, with the body covered to protect it from scratches.

The wish to keep a human hand in machine work has been handed down from Mr. Aizawa's predecessors. It gives Kobo Aizawa's tools their quiet warmth and natural shapes — and it is why they have lasted this long.

After our visit
Working closely with factories in Tsubame and across Japan, Kobo Aizawa keeps making tools that people trust for years. Their products look simple, yet have something that sets them apart. Seeing how they stay true to their origin, refuse to compromise on the details, and build up the small considerations of each maker, we understood why.

Our sincere thanks to Mr. Aizawa, Kobo Aizawa and everyone at the workshop for their cooperation.
