    流通 | Tosa Knife History: 5 Surprising Ways Tosa Blades Spread Across Japan

    Ishizuchi Kanamono Manufactory

    When I started looking deeper into Tosa knife history, I became curious about something I had never really thought about before.

    We often talk about how Tosa blades were forged, the blacksmiths who made them, and the traditions that survived for hundreds of years. But after researching the history of Tosa knives recently, another simple question came to mind:

    How did these blades actually get from the blacksmiths of Tosa into the hands of people elsewhere in Japan?

    I sell Tosa knives in Australia today, yet I honestly did not know much about how Tosa blades were distributed in the past. So, as with many of the subjects on this blog, I decided to look it up.

    Tosa Knife History Started With More Than Kitchen Knives


    Japanese nata (traditional Japanese forestry blade)

    One thing that becomes clear when researching Tosa knife history is that we should not imagine Tosa as simply a historical kitchen-knife production area.

    Kochi Prefecture, historically known as Tosa Province, has long been closely connected with forestry. Its warm, rainy climate supported extensive forests, and timber became an important resource.

    Working in those forests required cutting tools.

    Axes, hatchets, sickles and saws were essential working tools, and the demand for agricultural and forestry blades helped Tosa’s blacksmithing industry develop. During the early Edo period, policies encouraging forestry and the development of new farmland increased this demand significantly.

    In other words, these blades were not originally objects made to sit beautifully in a display case. They were tools made to work.

    The Forests Helped Tosa Blades Travel

    This was the part I found particularly interesting.

    Tosa’s blade industry developed alongside its timber industry. One example is the Tosa saw. Historical information from the Tosa Cutlery Distribution Center explains that Tosa saw production developed around Kataji, an area along the Monobe River that served as a gathering point for timber.

    So there was a natural relationship between the forests, the workers, the movement of timber and the tools required to work with it.

    As Tosa’s forestry culture developed, its blades gained a reputation as practical working tools.

    Some accounts also describe forestry workers carrying Tosa-made tools when travelling to work in other regions. Other workers saw and used these blades, helping their reputation spread beyond Kochi.

    That is very different from modern marketing.

    There was no Instagram, online advertising or SEO. A tool could build its reputation simply because someone used it every day and trusted it.

    Tosa Knife History and the Growth of Distribution


    A Traditional Tosa Blade Merchant

    By the Meiji period, the distribution story becomes clearer.

    Historical accounts of the Tosa blade industry indicate that around 1887, sales routes had expanded beyond the local area. They later spread throughout Shikoku and into the Chugoku region of western Honshu.

    As this happened, wholesalers dealing in forged blades began to develop, creating a more organised distribution system.

    I found this fascinating because it shows a transition.

    A blade could begin in a small workshop, pass through merchants and wholesalers, and eventually reach users far beyond the place where it had been forged.

    The blacksmith did not necessarily need to travel across Japan himself. A distribution network was beginning to connect regional craftsmanship with a much larger market.

    👉 INTERNAL LINK: Link here to “Handmade Japanese Knives — Why No Two Are Exactly the Same”

    Tosa Knife History Was Built Around Practical Tools

    The more I read about Tosa knife history, the more I feel that practicality is one of the keys to understanding Tosa blades.

    Their reputation was not created only by beautiful craftsmanship.

    These were blades expected to cut wood, clear land, harvest crops and perform demanding everyday work. Kitchen knives later became an important part of the tradition, but they belong to a much broader culture of forged working tools.

    Perhaps that is one reason I personally find Tosa knives so appealing.

    They can be beautiful, but they were never supposed to be beautiful only.

    From Tosa to Australia

    And this is where researching the past made me think about what I am doing today.

    Hundreds of years ago, Tosa blacksmiths made blades for people working in the forests, farms and kitchens of Japan. Over time, those blades travelled farther through workers, merchants and developing distribution networks.

    Today, the distance is much greater.

    I work directly with Ishizuchi Kanamono Seisakusho and bring handcrafted Tosa knives from Japan to Australia.

    Of course, modern shipping and online stores make distribution completely different. But when I look at the bigger picture, perhaps the basic idea has not changed as much as I expected.

    A blacksmith makes a tool.

    Someone believes in that tool.

    And then someone carries it to the next person who will use it.

    I did not know much about this side of Tosa knife history before researching it. Now, every time I unpack a shipment of Tosa knives here in Australia, I think I may be participating in a very small continuation of a journey that began long before me.

  • 土佐 Tosa | The Powerful History of Tosa Knives I Wanted to Know

    土佐 Tosa | The Powerful History of Tosa Knives I Wanted to Know

    When you work with something every day, sometimes you forget to ask where it actually came from.

    I sell Tosa knives in Australia, sourcing handcrafted Japanese knives directly from Shikoku, Japan. I have also spent more than 25 years working as a chef in Japan and Australia. I know how these knives feel in the hand, how they sharpen, and how they perform in a professional kitchen.

    But recently, I realised there was something I wanted to understand better.

    How did Tosa knives actually begin?

    I knew that Tosa had a long history of blacksmithing, but I wanted to look deeper into why this particular part of Japan became known for forged blades. What I found made me appreciate the history behind these knives even more.

    The History of Tosa Knives Goes Back Centuries

    Ishizuchi Kanamono Manufactory

    The story of Tosa knives is closely connected to the geography and working life of Kochi Prefecture, historically known as Tosa Province.

    Kochi is a mountainous region with extensive forests. For generations, forestry was an important part of life there, and people needed strong, dependable tools for cutting trees, clearing land and working in the mountains.

    That naturally created demand for forged tools such as axes, hatchets, sickles and saws.

    The history, however, goes back even further.

    Sword-making techniques are said to have reached Tosa during the Kamakura period. By 1590, the Chōsokabe Land Survey Records documented 399 blacksmiths in Tosa Province.

    That number surprised me.

    It shows that blacksmithing was already deeply established in the region more than 400 years ago.

    How Tosa Knives Grew With Forestry and Agriculture


    From Agricultural Tools to Tosa Knives

    The major development of Tosa forged blades came during the early Edo period.

    In 1621, reforms by the Tosa Domain encouraged the development of forestry and new agricultural land. As forestry and farming expanded, so did the need for reliable cutting tools.

    Blacksmiths responded to that demand.

    Over time, production increased and techniques improved. What began as tools essential for daily work gradually developed into what we now recognise as the tradition of Tosa Uchihamono, or Tosa forged blades.

    This is one thing I find particularly interesting about Tosa.

    The tradition was not created simply to make beautiful objects.

    These were working tools.

    They had to cut. They had to survive hard use. And they had to be practical enough for people who depended on them for their livelihood.

    Tosa Knives and the Tradition of Free Forging


    Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    Another characteristic that caught my attention while researching Tosa knives was something known as jiyū tanzō, or “free forging.”

    Rather than relying entirely on fixed moulds, Tosa blacksmiths traditionally forged different shapes and sizes according to their intended purpose.

    That flexibility made sense in a region where people needed many different kinds of blades for forestry, agriculture and everyday life.

    Even today, you can see something of that character in handcrafted Japanese knives.

    Small differences in hammer marks, blade shape and finish are not necessarily imperfections. To me, they are reminders that a knife was made by human hands rather than simply coming from an automated production line.

    From Traditional Tosa Blades to Modern Kitchen Knives

    Today, Tosa knives are known far beyond Kochi.

    In 1998, Tosa Uchihamono was officially designated as a Traditional Craft of Japan. The tradition includes not only kitchen knives but also axes, sickles, hatchets, saws and other working blades.

    Modern Japanese kitchen knives have naturally evolved as well.

    Today we can find traditional carbon steels such as Aogami alongside stainless steels and modern powder metallurgy steels. Handles, finishes and blade styles have changed to suit contemporary cooks, but the connection between Japanese knife making and traditional forging remains.

    👉 INTERNAL LINK: Learn more about Aogami and Shirogami steels

    👉 INTERNAL LINK: Read my guide to Ginsan steel and why I like it for kitchen knives

    For me, that combination is what makes the history of Tosa so interesting.

    It is not simply a tradition frozen in the past.

    It has continued to evolve.

    Why the History of Tosa Knives Matters to Me


    Wooden Box for Traditional Knives

    After looking into this history, I see the knives I work with a little differently.

    I started Asaoya Yaichi because I wanted to bring genuine handcrafted Japanese knives from Shikoku to Australia. As a chef, my first concern will always be practical: does the knife actually work well in a kitchen?

    But there is another side to it.

    Learning about Tosa knives reminded me that Japanese blades did not develop only as kitchen tools. Their history is connected to forestry, agriculture, sword-making knowledge and generations of blacksmiths adapting their skills to what people actually needed.

    That history does not automatically make every knife perfect.

    But I think understanding where these traditions came from gives us a better appreciation of why Japanese forged knives are the way they are today.

    Perhaps that is what I like most about the history of Tosa.

    These blades were never meant to exist only behind glass.

    They were made to be used.

    And more than 400 years later, that practical spirit can still be found in the Japanese forging traditions that continue across Shikoku today.

    一目惚れ Hitomebore | 7 Powerful Reasons to Fall in Love With a Japanese Knife


    Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    I sell Japanese knives for a living. The problem is, sometimes I don’t want to sell them.

    Right now, there is one Japanese knife in the Asaoya Yaichi collection that I keep looking at and thinking, “Maybe I should keep this one for myself.”

    It is an Aogami #2 knife with a polished blade, a green Micarta handle and a beautiful turquoise accent.

    I originally selected it to sell.

    That was the plan, anyway.

    A Japanese Knife Is More Than Its Specifications


    180mm Santoku SG2 Rosewood Octagonal Handle

    After more than 25 years working as a professional chef in Japan and Australia, I have used many Japanese knives. But honestly, I have never chosen a knife by specifications alone.

    Of course, steel matters. Hardness matters. Blade shape, handle, balance and craftsmanship matter too.

    Over the years, I have developed my own preferences. I personally like Aogami steels, for example. From my experience, I find them relatively easy to sharpen and enjoyable to use.

    But there is another side to choosing a Japanese knife that is much harder to put into numbers.

    Sometimes, you simply see a knife and think:

    “That’s the one.”

    The Japanese Knife That Caught My Eye


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    That is exactly what happened with this Aogami #2 knife.

    I like the polished blade because it does not immediately have the rustic appearance many people associate with carbon steel. Underneath that clean finish, however, is Aogami #2 — a steel I already know and like.

    Then there is the handle.

    Samurai Century

    The green Micarta gives it a modern appearance, while the turquoise band adds something completely different.

    To my eyes, there is even a little Wabi-Sabi in that turquoise detail. It is unusual without being too flashy, and it gives the knife its own character.

    I have plenty of knives around me.

    But I keep looking at this one.

    That probably says something.

    Choosing Japanese Knives for Asaoya Yaichi

    Ishizuchi Kanamono Manufactory

    There is also a reason this story matters to me as the person behind Asaoya Yaichi.

    When you buy a Japanese knife online, you cannot physically pick up every knife before making your decision.

    I understand that.

    That is why I believe the selection before a knife appears in the store is important.

    I have spent more than 25 years using knives in professional kitchens. When selecting knives for Asaoya Yaichi, I want to actually see them, hold them and look closely at their quality, construction and overall feel.

    I do not choose knives simply because a specification sheet looks impressive.

    I want to offer knives that I would be happy to own myself.

    👉 INTERNAL LINK: 均衡 Kinkō | 7 Powerful Reasons Japanese Knife Balance Matters More Than You Think

    Quality Still Matters

    Love at first sight is not enough by itself.

    A Japanese knife is still a working tool.

    I do not believe an expensive knife is automatically perfect for everyone, but I do believe good materials, skilled craftsmanship and careful finishing have real value.

    Very cheap knives can do a job, but there are usually compromises somewhere.

    A quality knife can also change the way you treat it. When you own something you genuinely value, you tend to clean it carefully, sharpen it properly and want to keep it for many years.

    Sometimes a Japanese Knife Just Speaks to You

    We can talk about steel, hardness and blade geometry all day.

    Those things are important, and I think anyone buying a Japanese knife should understand the basics.

    👉 INTERNAL LINK: 切味 Kireaji | 7 Truths About What Makes a Japanese Knife Feel Sharp

    But I also think it is perfectly fine to choose a knife because something about it simply catches your eye.

    For me, it is this one.

    I like the Aogami #2 steel.

    I like the polished blade.

    And I love that turquoise detail.

    I selected this knife for Asaoya Yaichi because I thought it was something worth offering to our customers.

    The only problem is that I may have selected it a little too well.

    Now I want it for myself.

    Maybe that is Hitomebore — love at first sight.

    And sometimes, that is all it takes for a Japanese knife to become special.

  • 祭 Matsuri | 100kg of Bluefin Tuna and the Hidden Reality Behind the James St Festival

    祭 Matsuri | 100kg of Bluefin Tuna and the Hidden Reality Behind the James St Festival

    James St Festival

    James St Festival Part 2 continues my behind-the-scenes journey through one of Brisbane’s biggest food festivals. After the tuna cutting show ends, the real work begins as nearly 100kg of bluefin tuna sashimi is prepared using handcrafted Japanese knives.

    When people visit the James St Festival, they remember the atmosphere, the incredible food, and the famous tuna cutting show.

    As a sushi chef working behind the scenes, my memories are very different.

    For me, the real challenge began the moment the applause ended.

    This is Part 2 of my behind-the-scenes journey through one of Brisbane’s biggest food festivals—a day filled with preparation, teamwork, and the Japanese knives I rely on every day.

    James St Festival Tuna Cutting Show Begins

    Blue fin Tuna is

    By late morning, hundreds of visitors had gathered around the stage for one of the festival’s biggest attractions—the bluefin tuna cutting show.

    Two enormous whole bluefin tuna were carefully carried onto the stage. Each fish was so heavy that it took four people to lift it safely.

    Seeing the crowd’s excitement was incredible. For many people, it was probably the first time they had ever seen a whole bluefin tuna up close.

    Ironically, I didn’t get to enjoy the show myself.

    While everyone else watched the demonstration, I had already been assigned to help another section of the kitchen prepare for what would happen next.

    In a professional kitchen, someone always has to stay behind the scenes to keep everything moving.

    James St Festival Gets Even Busier After the Show

    The moment the demonstration finished, large sections of freshly cut bluefin tuna began arriving back in the kitchen.

    From that point on, nobody stopped moving.

    Every chef returned to their station.

    Cut.

    Trim.

    Slice.

    Pack.

    Restock.

    Repeat.

    That rhythm continued for hours.

    Every tray of sashimi that left the kitchen had to be replaced immediately.

    Customers kept lining up, and the bluefin tuna disappeared almost as quickly as we could prepare it.

    There was no time to slow down.

    Every slice had to be clean, consistent, and ready to serve.

    ➡ Internal Link: Sujihiki Knives

    James St Festival Served Nearly 100kg of Bluefin Tuna

    Ishizuchi Sujihiki Knife

    Throughout the day, we prepared and sold nearly 100 kilograms of bluefin tuna as sashimi.

    Watching that amount of premium fish disappear throughout the day was something I’ll never forget.

    Preparing sashimi at that volume requires more than speed.

    It demands consistency, concentration, and respect for every piece of fish.

    Every cut matters.

    Even after hours of continuous slicing, every piece must look as good as the very first one.

    That’s one of the biggest differences between cooking professionally and cooking at home.

    ➡ Internal Link: Beginner’s Guide to Japanese Kitchen Knives

    James St Festival Depends on Japanese Knives

    Ishizuchi Kanamono Manufactory

    Days like this remind me why I trust handcrafted Japanese knives.

    When you’re slicing fish continuously for hours, a knife becomes much more than a tool.

    It becomes an extension of your hands.

    A well-balanced knife reduces fatigue.

    A razor-sharp edge produces cleaner slices.

    Most of the knives I used that day were handcrafted by Ishizuchi Metalworks in Kochi, Japan.

    Among them was one knife that has been with my family for over 40 years—a Kiya Yanagiba originally passed down from my mother.

    Even after decades of professional use, it continues to perform beautifully.

    To me, that’s what makes a truly great Japanese knife.

    It’s not something you simply own.

    It’s something you can pass on to the next generation.

    ➡ Internal Link: Carbon Steel vs Stainless Steel

    ➡ Internal Link: Why Do Japanese Knives Rust So Easily?

    James St Festival Is Built on Teamwork

    Visitors usually remember the chef standing behind the counter.

    What they rarely see is the entire team working together behind the scenes.

    While one chef slices tuna, another prepares the display, another packs fresh sashimi, while others replenish stock, clean equipment, and keep every station organised.

    Nobody could manage an event like this alone.

    The smooth service that customers experience is only possible because every member of the team works together toward the same goal.

    That is one of the greatest lessons I take away from every major food festival.

    ➡ Internal Link: James St Festival Part 1 – Before the Crowd Arrived

    James St Festival Ends Quietly

    As the afternoon came to an end, the crowds slowly disappeared.

    Inside the kitchen, we cleaned our knives, washed every workstation, packed away equipment, and finally had a chance to take a breath.

    Only then did the exhaustion begin to sink in.

    For visitors, the James St Festival lasts only a few enjoyable hours.

    For the chefs behind the scenes, those few hours represent an entire day of preparation, concentration, teamwork, and hard work.

    After more than 25 years as a professional chef, experiences like this still remind me why I love this profession.

    Creating memorable experiences for people is always worth the effort.

    Final Thoughts

    This two-part series has been a little different from my usual articles about Japanese knives.

    Instead of focusing only on steel, blade shapes, or craftsmanship, I wanted to share what life really looks like behind the scenes of one of Brisbane’s biggest food festivals.

    Every handcrafted Japanese knife has a story.

    Every chef has a story.

    And every unforgettable meal begins long before the first customer arrives.

    If you enjoyed following my journey through the James St Festival, I invite you to explore more stories about traditional Tosa knives, Japanese craftsmanship, and the tools I trust every day as a professional sushi chef.

    Whether you’re looking for your first Japanese knife or simply want to learn more about the people and traditions behind them, you’ll find plenty of guides, stories, and handcrafted knives at Asaoya Yaichi.

  • 祭 Matsuri | 12 Hours Behind the James St Festival Before the Crowd Arrived

    祭 Matsuri | 12 Hours Behind the James St Festival Before the Crowd Arrived

    This time, I’d like to share something a little different.

    Instead of talking about Japanese knives, steel, or traditional craftsmanship, I’m taking you behind the scenes of one of Brisbane’s biggest food events.

    As a professional sushi chef with more than 25 years of experience, I thought it would be interesting to show what happens before the crowds arrive at the James St Festival.

    This is the first chapter of that story.

    The James St Festival

    The James St Festival is one of Brisbane’s most popular annual events, attracting thousands of visitors who come to enjoy incredible food, live music, local businesses, and the unique atmosphere that fills James Street every winter.

    Most people only see the finished experience—the beautifully presented food, the smiling chefs, and the lively streets packed with visitors.

    Very few people ever see what happens before the festival opens.

    Long before the first customer walks through the gates, chefs, kitchen staff, and event teams are already working at full speed behind the scenes.

    As a professional sushi chef with more than 25 years of experience, I thought it would be interesting to share a different side of the James St Festival—one that most visitors never have the chance to witness.

    This is the first chapter of that story.

    James St Festival Begins Before Sunrise

    Sunrise

    My alarm rang at 6:00 a.m.

    Thirty minutes later, I climbed onto my beloved e-scooter and headed toward the train station.

    Although Brisbane’s winters are relatively mild, riding an e-scooter before sunrise is another story entirely.

    The freezing air rushed past my face, and the cold wind against my ears was almost painful.

    For a moment I questioned why anyone would willingly leave a warm bed this early on a Sunday morning.

    Still, festival day had arrived.

    There was work to do.

    I reached the station just in time for the 6:55 a.m. train.

    As I stood on the platform, the first light of the morning slowly appeared across the horizon.

    The sunrise always feels special to me.

    No matter how busy life becomes, watching the beginning of a new day reminds me why I love working as a chef.

    It represents another opportunity to improve, create, and challenge myself.

    The train was almost empty.

    Only a handful of passengers sat quietly as we travelled toward the city.

    Every time the doors opened, another wave of icy air entered the carriage, making everyone pull their jackets a little tighter.

    At 7:39 a.m., I stepped off the train, climbed back onto my e-scooter, and made the short journey to work.

    James St Festival Was Already Coming to Life

    As I approached James Street, I immediately realised this wasn’t an ordinary Sunday.

    Roads had been closed.

    Temporary barriers lined the streets.

    Festival tents stretched along the footpaths.

    Large speakers had been installed.

    Staff members hurried between stalls carrying equipment and supplies.

    The James Street I see almost every week had transformed overnight into something completely different.

    Although visitors had not yet arrived, there was already a sense of excitement in the air.

    Everyone knew that within only a couple of hours these quiet streets would become one of Brisbane’s busiest destinations.

    Seeing the transformation before the crowds arrive is something most people never experience.

    For those of us working behind the scenes, however, this is where the James St Festival truly begins.

    James St Festival Morning Timeline


    Behind the Scenes 

    Before the festival officially opened, my morning looked like this.

    Time

    Activity

    6:00 a.m.

    Woke up

    6:30 a.m.

    Left home on my e-scooter

    6:55 a.m.

    Boarded the train

    7:39 a.m.

    Arrived at the station

    8:00 a.m.

    Arrived at work

    8:15 a.m.

    Began preparing sashimi

    10:00 a.m.

    James St Festival officially opened

    By the time most people were deciding where to have breakfast, our kitchen had already been working for nearly two hours.

    James St Festival Preparation Starts with Japanese Knives

    Ishizuchi Kanamono Manufactory

    After arriving at work, there was no time to relax.

    I changed into my uniform, washed my hands, organised my workstation, and immediately began preparing sashimi.

    For the entire day, my primary responsibility would be tuna.

    That meant slicing, portioning, trimming, and preparing an enormous amount of fish before the lunch rush began.

    Unlike a normal restaurant service, a major event like the James St Festival requires multiple knives ready for continuous work.

    When one knife begins to lose its razor-sharp edge, another immediately takes its place.

    Efficiency matters.

    Precision matters even more.

    Most of the knives laid out in front of me were handcrafted by Ishizuchi Metalworks, the same workshop that supplies the handcrafted Japanese knives available through Asaoya Yaichi.

    These knives are not displayed simply because they look beautiful.

    They are the knives I genuinely trust in a professional kitchen.

    Among them sits one knife that always reminds me why Japanese craftsmanship deserves such respect.

    A Kiya knife passed down from my mother.

    It is now more than 40 years old, yet it still performs remarkably well in professional service.

    Every time I use it, I am reminded that a truly well-made Japanese knife is not something you replace every few years.

    It becomes part of your story.

    With proper care, it can serve not only one chef, but an entire family across generations.

    That is the beauty of traditional Japanese craftsmanship.

    James St Festival Preparation Never Stops

    Slicing Tuna

    Preparation began with tuna that had already been partially prepared the previous day.

    Cut.

    Trim.

    Slice.

    Repeat.

    Once enough tuna had been portioned, it all needed to be packed carefully into trays.

    Wasabi

    Then came fresh wasabi.

    Pickled ginger.

    Containers.

    Labels.

    Cleaning.

    Restocking.

    Every small task had to be completed before customers arrived.

    Professional kitchens never focus on just one job at a time.

    Everything happens simultaneously.

    While slicing tuna, someone else prepares garnishes.

    Another person organises packaging.

    Someone checks stock levels.

    Another cleans benches and equipment before the next task begins.

    The smooth experience customers enjoy is only possible because dozens of small jobs happen together behind the scenes.

    Packing

    By 10:00 a.m., the James St Festival officially opened.

    Almost instantly, the atmosphere outside changed.

    Music echoed through James Street.

    Families and friends filled the walkways.

    Queues quickly formed outside popular food stalls.

    Laughter spread throughout the precinct.

    From inside the kitchen, we could hear the excitement building with every passing minute.

    Although we rarely had time to look outside, we knew exactly what was happening beyond the kitchen doors.

    The festival had finally begun.

    The Biggest Moment of the Day Was About to Begin

    As more visitors arrived, the anticipation inside the kitchen continued to grow.

    Waiting backstage were two whole bluefin tuna, ready for one of the festival’s biggest attractions—the live tuna cutting demonstration.

    For the visitors outside, it would be an exciting show.

    For those of us inside the kitchen, it marked the beginning of an entirely different challenge.

    What happened after those tuna returned to the kitchen would become the busiest and most intense part of the entire day.

    That story continues in Part 2, where I’ll take you behind the scenes of the live tuna cutting demonstration, the incredible rush that followed, and how nearly 100 kilograms of tuna sold out during one unforgettable James St Festival.

  • The True Value of Japanese Knives | 7 Reasons They Are Worth the Investment

    The True Value of Japanese Knives | 7 Reasons They Are Worth the Investment

    Why are Japanese knives so expensive?

    .

    Why are Japanese knives so expensive?
    It is one of the first questions many people ask when they begin looking for a high-quality Japanese kitchen knife. The answer is not simply branding or appearance. The price often reflects the quality of the steel, the skill of the craftsman, the time required to make the knife, and the performance it can provide over many years.

    Some Japanese kitchen knives can be purchased for a relatively affordable price, while others may cost several hundred dollars or even more. Custom-made knives created by highly skilled craftsmen can reach prices that surprise people who are used to buying mass-produced kitchen knives.

    However, the price of a Japanese knife is not simply based on appearance, branding, or popularity.

    In many cases, the price reflects the quality of the steel, the skill of the craftsman, the time required to make the knife, and the performance it can provide over many years.

    That does not mean everyone needs an expensive knife.

    The real question is not whether a Japanese knife is expensive. The real question is whether the knife offers enough value for the person using it.

    Why Are Japanese Knives So Expensive?

    Ishizuchi Kanamono Manufactory

    Japanese knives are often made very differently from standard factory-produced kitchen knives.

    Many ordinary knives are manufactured in large factories using automated machinery. This allows thousands of similar knives to be produced quickly and sold at a lower price.

    Handcrafted Japanese knives are commonly made in smaller workshops, sometimes by individual blacksmiths, sharpeners, handle makers, and finishers.

    Each stage requires experience, time, and attention.

    The price is therefore not only for the physical knife. It also reflects generations of accumulated knowledge and craftsmanship.

    1. Japanese Knives Use High-Quality Steel

    Asaoya Yaichi

    One major reason Japanese knives are expensive is the quality of the steel.

    Japanese knife makers use steels such as Aogami, Shirogami, Ginsan, VG10, and SG2. Each steel has different characteristics, including sharpness, edge retention, ease of sharpening, corrosion resistance, and toughness.

    Premium steel is more expensive to purchase and can also be more difficult to work with.

    The steel must be heated, forged, shaped, hardened, tempered, ground, and sharpened correctly. A small mistake during heat treatment can reduce the performance of the finished blade.

    A well-made knife is therefore not only about using good steel. It is about understanding how to bring out the best qualities of that steel.

    2. Skilled Craftsmen Make Many Japanese Knives by Hand

    A handmade Japanese knife requires a level of skill that usually takes many years to develop.

    Forging a blade, controlling its thickness, creating the correct profile, and producing a fine cutting edge cannot be mastered quickly.

    Even two knives made from the same steel can perform differently depending on the skill of the maker.

    An experienced craftsman understands how the steel responds to heat, pressure, grinding, and sharpening. Much of this knowledge is developed through years of practical experience rather than simply following written instructions.

    When you purchase a handcrafted Japanese knife, part of the price supports the skill and time of the people who made it.

    ➡️Read more: Mass-Produced vs Hand-Forged Japanese Knives – What’s the Difference?

    3. Japanese Knives Are Often Produced in Small Quantities

    Many Japanese knife workshops do not produce huge quantities of knives.

    Some workshops make only a limited number of blades each week or month. Others may produce a particular design only when the right steel, handle material, or craftsman is available.

    Small-batch production makes it difficult to reduce costs in the same way as large-scale factories.

    However, it also allows more attention to be given to each knife.

    Small variations in the finish, hammer marks, blade shape, or handle are often part of the character of a handmade knife rather than signs of poor quality.

    This individuality is one reason many people are attracted to traditional Japanese knives.

    4. Heat Treatment Requires Time and Precision

    Heat treatment is one of the most important stages in knife making.

    The blade must be heated to a carefully controlled temperature and then cooled correctly. It is later tempered to balance hardness with durability.

    If a blade is too soft, it may lose its sharp edge quickly. If it is too hard, it may become more vulnerable to chipping.

    High-performance Japanese knives are often hardened more than typical Western-style kitchen knives. This allows them to take a very fine edge and maintain sharpness for longer.

    Achieving this balance requires experience and precision.

    The customer may not be able to see the quality of the heat treatment, but it has a major effect on how the knife performs.

    5. Sharpening and Finishing Require Considerable Labour

    A Japanese knife may appear simple, but the final stages require a great deal of work.

    The blade must be ground to the correct thickness, the bevels must be shaped, and the cutting edge must be sharpened evenly.

    Some knives also receive additional finishes such as kurouchi, nashiji, tsuchime, Damascus patterns, mirror polishing, or hand engraving.

    The handle must also be fitted correctly.

    Traditional Japanese handles may use magnolia, walnut, rosewood, ebony, buffalo horn, micarta, or other materials. The quality of the handle, spacer, ferrule, and installation can all influence the final cost.

    These details may not change the basic function of the knife, but they can improve comfort, balance, durability, and appearance.

    6. A Good Japanese Knife Can Last for Many Years


    A Kiya Yanagiba Knife Passed Down from My Mother, Over 40 Years Old

    A well-maintained Japanese knife is not a disposable product.

    With proper sharpening, cleaning, drying, and storage, it can be used for many years. Some knives are passed from one generation to the next.

    This changes the way the price should be considered.

    A cheap knife that is replaced repeatedly may eventually cost more than one high-quality knife that is maintained correctly.

    However, long life is not automatic.

    Even an expensive Japanese knife can rust, chip, crack, or become damaged if it is used incorrectly. Carbon steel knives must be kept clean and dry, and thin blades should not be used to cut frozen food, hard bones, or other unsuitable materials.

    The value of a good knife comes from both its construction and the care given by its owner.

    7. Japanese Knives Can Improve the Experience of Cooking

    A high-quality knife does more than cut food.

    It can improve control, precision, efficiency, and enjoyment.

    A sharp knife requires less pressure, which can make delicate cutting easier. It can also help produce cleaner slices of fish, meat, vegetables, herbs, and fruit.

    For professional chefs, these differences can be important because a knife is used for many hours every week.

    For home cooks, the benefit may simply be that food preparation becomes more enjoyable.

    This is difficult to measure with money, but it is one of the main reasons people are willing to invest in quality tools.

    A Chef I Work with Ordered a ¥250,000 Knife

    One of the chefs I work with ordered a custom-made knife when he returned to Japan.

    The knife cost approximately ¥250,000.

    To some people, that may sound far too expensive for a kitchen knife.

    However, for him, the knife was worth the price.

    It was not simply a decorative object or an expensive possession. It was a professional tool that he expected to use regularly. It reflected his preferences, his working style, and the kind of performance he wanted from his equipment.

    He understood what he was buying and believed the knife would provide enough value to justify the cost.

    That does not mean everyone should spend ¥250,000 on a knife.

    Most people do not need to.

    The important lesson is that value is personal.

    One person may be completely satisfied with an affordable stainless steel knife. Another person may prefer to invest in a handmade carbon steel knife. A professional chef may be willing to pay much more for a custom blade that matches a particular cutting style.

    None of these choices is automatically right or wrong.

    Are Expensive Japanese Knives Always Better?


    210mm Sujihiki Aogami #2 Kurouchi Magnolia Handle
    A$270.00

    No.

    A higher price does not always guarantee that a knife is better for every user.

    Some knives are expensive because of rare materials, complex polishing, decorative finishes, limited production, famous makers, or custom specifications.

    These features may be valuable to collectors or experienced chefs, but they may not be necessary for a beginner.

    The best knife depends on what you cook, how often you use it, how comfortable you are with maintenance, and how much you are willing to spend.

    A person who does not want to worry about rust may be happier with Ginsan, VG10, or SG2 stainless steel.

    A person who enjoys sharpening and values traditional character may prefer Aogami or Shirogami carbon steel.

    The most expensive knife is not automatically the best choice.

    How to Decide Whether a Japanese Knife Is Worth the Price

    Before purchasing a Japanese knife, consider how you will use it.

    ➡️ New to Japanese knives? Read our: Beginner’s Guide to Japanese Kitchen Knives

    Think about the type of food you prepare, the knife shape you need, the steel you can maintain, and the size that feels comfortable.

    It is also important to buy from a seller who clearly explains the steel, blade construction, handle, maintenance requirements, and intended use.

    A good knife should suit the user rather than simply impress them.

    At Asaoya Yaichi, the goal is not to convince every customer to purchase the most expensive knife.

    The goal is to help people understand what they are buying and choose a knife that offers genuine value for their needs.

    Final Thoughts: Why Are Japanese Knives So Expensive?

    Japanese knives can be expensive because they combine high-quality steel, skilled craftsmanship, careful heat treatment, detailed sharpening, small-batch production, and traditional knowledge.

    These qualities require time and cannot always be reproduced cheaply.

    However, price alone does not determine value.

    For one person, an affordable knife may be the perfect choice. For another, a handcrafted knife may be worth several hundred dollars. For a professional chef, even a ¥250,000 custom knife may represent a reasonable investment.

    The best knife is not necessarily the most expensive knife.

    It is the knife that suits your work, your cooking, your preferences, and your idea of value.

    A good Japanese knife should not be purchased simply because it is expensive.

    It should be purchased because, for the person using it, it is worth owning.

  • A Knife That Earned My Respect

    A Knife That Earned My Respect

    Part 2 – A Knife That Grows With You

    Knife Care

    The more I used traditional Tosa knives, the more I realised something.

    The blacksmith’s work doesn’t end when the knife leaves the forge.

    In many ways, that’s where the next chapter begins.

    A handcrafted knife is not meant to remain exactly as it was on the day it was made.

    It is meant to grow alongside the person who uses it.

    That may sound unusual at first.

    But after spending more than twenty-five years working as a chef, I have come to believe it is true.

    A Knife That Learns Your Hands


    A Knife That Learns Your Hands

    Every chef works differently.

    Some prefer a finer edge for delicate slicing.

    Others leave a little more strength behind the edge for heavier work.

    Some sharpen frequently.

    Others wait until the knife tells them it is time.

    None of these approaches are necessarily right or wrong.

    Over time, every sharpening subtly changes the knife.

    Every service leaves another memory.

    Every meal adds another chapter.

    Eventually, something remarkable happens.

    The knife no longer feels like a tool made by someone else.

    It feels like your knife.

    That is why I often say a great knife isn’t finished by the blacksmith alone.

    The blacksmith begins the story.

    The owner completes it.

    Beauty Beyond Perfection


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handl

    When many people imagine a premium Japanese knife, they picture a flawless mirror finish.

    I used to think the same way.

    Today, I see beauty differently.

    A softened Kurouchi finish.

    A natural patina on carbon steel.

    Small marks left behind after years of careful sharpening.

    These are not imperfections.

    They are evidence of a knife that has been trusted.

    To me, that is a far more meaningful kind of beauty.

    It reminds me of the Japanese philosophy often described as Wabi-Sabi—finding beauty in authenticity, simplicity and the passage of time.

    The character of a handcrafted knife is not frozen on the day it is forged.

    It continues to evolve with every meal it helps create.

    Different Regions, Different Traditions


    150mm Kiritsuke Thick Deba Aogami #2 Kurouchi Walnut Octagonal Handle

    Japan is home to many extraordinary knife-making regions.

    Sakai is renowned for its precision and refined finishing.

    Kyoto is admired for its elegance and long tradition of craftsmanship.

    I have enormous respect for both.

    Tosa simply tells a different story.

    Its blacksmiths were shaped by a region where tools were expected to work hard every single day.

    Generations of craftsmen forged tools for farming, forestry and fishing long before they became known for kitchen knives.

    That heritage is still visible today.

    A Tosa knife doesn’t try to hide where it came from.

    Its forged texture, Kurouchi finish and practical design proudly reflect its working roots.

    That is exactly what many people come to appreciate.

    Some collectors are captivated by the refined elegance of Sakai or Kyoto.

    Others are drawn to the rugged honesty of Tosa.

    Many enjoy collecting knives from different regions because each one tells a different story about Japan’s remarkable craft traditions.

    It isn’t about deciding which is better.

    It is about appreciating the unique character each tradition offers.

    Why Asaoya Yaichi Exists

    Ishizuchi Kanamono Manufactory

    People sometimes ask why I decided to start Asaoya Yaichi.

    The answer is simple.

    I wanted to introduce Australians to authentic handcrafted Tosa knives.

    Not because they are fashionable.

    Not because they are the most expensive.

    But because I believe they deserve to be recognised for what they truly are.

    For too long, I have seen mass-produced knives marketed as “Japanese knives” without representing the traditions that made Japanese craftsmanship respected around the world.

    That isn’t what I wanted to share.

    I wanted to introduce knives with a genuine story.

    Knives made by skilled blacksmiths whose techniques have been handed down through generations.

    Knives that improve with care instead of losing their value.

    Knives that can still be used decades from now—just like the Yanagiba my mother used for around twenty years before passing it on to me, and that I’ve continued using for another twenty.

    That knife reminds me that a truly great knife isn’t measured by how it looks on the first day.

    It’s measured by how faithfully it serves over a lifetime.

    More Than Selling Knives

    Working with Ishizuchi Kanamono Seisakusho has strengthened that belief.

    For more than a century, they have remained committed to supporting authentic craftsmanship and the people behind it.

    That philosophy reflects exactly what I hope Asaoya Yaichi can become.

    Not simply a shop.

    But a bridge.

    A bridge between the traditional blacksmiths of Tosa and the people who will use their work every day here in Australia.

    Every knife carries the skill of the craftsman who forged it.

    But its future belongs to the person who chooses to use it.

    That relationship is what makes handcrafted knives so special.

    A Final Thought

    If there is one lesson I have learned after more than twenty-five years as a chef, it is this:

    The best knife is not always the one that impresses you on the first day.

    Sometimes, the best knife is the one that quietly earns your respect over many years.

    That is exactly what happened to me.

    I didn’t fall in love with Tosa knives the moment I first picked one up.

    I fell in love with them after cooking with them.

    After sharpening them.

    After trusting them.

    That journey changed the way I looked at knives forever.

    It is also the reason Asaoya Yaichi exists today.

    If you’ve always believed traditional Japanese knives are difficult to maintain, you may be surprised.

    With a little knowledge and regular care, a handcrafted knife can stay with you for decades.

    In future articles, I’ll be sharing practical knife care, sharpening techniques, and maintenance tips to help you get the very best from your knife—whether you’re a professional chef or cooking at home.

    If this article encourages even one person to look beyond appearances and discover the craftsmanship, history and spirit behind a traditional Tosa knife, then I believe I have achieved something meaningful.

    Because we are not simply preserving knives.

    We are helping preserve the people, the skills and the traditions that continue to shape them.

  • A Knife That Earned My Respect

    A Knife That Earned My Respect

    Why I Chose Tosa Knives


    165mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    I’ll be honest.

    The first time I held a traditional Tosa knife, I wasn’t impressed.

    At that stage of my career, I believed the best Japanese knives had to look a certain way.

    Mirror-polished.

    Beautifully finished.

    Elegant.

    To me, that was what a premium knife looked like.

    Then I picked up a traditional Kurouchi Tosa knife.

    It felt different.

    It looked different.

    If I’m being completely honest, I didn’t really like it.

    It seemed rough.

    Almost unfinished.

    I couldn’t understand why so many people respected it

    Looking back now, I realise the knife wasn’t the problem.

    I simply hadn’t lived with it long enough.

    Twenty-Five Years Behind the Knife

    @Asaoya_yaichi

    For more than twenty-five years, I worked as a chef in both Japan and Australia.

    Except for my days off, I spent almost every day with a knife in my hand.

    Preparing fish.

    Breaking down ingredients.

    Serving customers who expected consistency every single service.

    A professional kitchen teaches you something that catalogues and advertisements never can.

    A knife isn’t judged by how beautiful it looks when it’s new.

    It’s judged by how it performs after years of work.

    After thousands of sharpenings.

    After countless services.

    After becoming part of your own hands.

    The Knife That Taught Me This Lesson


    A 40-Year-Old Yanagiba Knife My Mother Passed Down to Me

    The most valuable knife I own isn’t the newest.

    It isn’t the most expensive.

    It’s a Yanagiba that belonged to my mother.

    She loved cooking, and she cared for that knife for decades.

    Today, around forty years after it first entered our family, I still use it.

    Every time I sharpen it, I’m reminded that a great knife isn’t something you simply buy.

    It’s something you build a relationship with.

    Every sharpening changes it.

    Every meal leaves a memory.

    Every year gives it more character.

    The knife I use today is no longer exactly the knife my mother once held.

    It has become part of both our stories.

    That is something money cannot buy.

    Discovering Tosa Again


    120mm Petty Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    Years later, something unexpected happened.

    My brother-in-law had a close relationship with Ishizuchi Kanamono Seisakusho.

    Through that connection, I received several sample knives.

    At first, I didn’t expect much.

    After all, my first impression of traditional Tosa knives had never been particularly strong.

    But I decided to use them.

    Not for a day.

    Not for a week.

    I used them in the way a chef truly tests a knife.

    Day after day.

    Service after service.

    Sharpening them.

    Maintaining them.

    Learning them.

    Slowly, my opinion began to change.

    What I had once mistaken for roughness turned out to be honesty.

    What I had once considered simple became incredibly practical.

    The knife wasn’t trying to impress me on the first day.

    It was asking me to discover it over time.

    That is when I truly began to understand Tosa knives.

    More Than a Supplier

    Ishizuchi Kanamono Manufactory

    As I learned more about Ishizuchi Kanamono Seisakusho, I realised that their story reflected the very philosophy I had begun to appreciate.

    Their history dates back more than one hundred years to the early Taisho era, when the company began as Ishizuchi Agricultural Machinery.

    Its purpose was simple: to provide dependable tools for people whose livelihoods depended on them.

    Farmers.

    Foresters.

    Fishermen.

    People who worked with their hands every day.

    As Japan changed, so did the company.

    Today, Ishizuchi Kanamono Seisakusho works alongside traditional Tosa blacksmiths, helping preserve generations of craftsmanship while introducing authentic Tosa knives to people around the world.

    That story resonated deeply with me.

    These knives were never created simply to impress someone in a showroom.

    They were created to be used.

    Maintained.

    Sharpened.

    Trusted.

    Perhaps that is why my opinion changed so dramatically.

    I had been judging these knives by how they looked.

    Instead, I should have judged them by how they lived.

    That simple realisation changed the way I looked at Tosa knives forever.

    It is also the reason Asaoya Yaichi exists today.

    Not simply to sell handcrafted knives.

    But to introduce the people, traditions and craftsmanship behind every blade, ensuring that the remarkable spirit of Tosa continues to be appreciated by future generations.

    Asaoya Yaichi – Authentic Tosa Knives

    Thank you for taking the time to read my story.

    In Part 2 – A Knife That Grows With You, I’ll share why I believe the finest handcrafted knives are never truly finished when they leave the blacksmith, but continue to grow alongside the people who use them.

    The blacksmith begins the story.

    The owner completes it.

  • Why I Started Asaoya Yaichi | Authentic Tosa Knives in Australia

    Why I Started Asaoya Yaichi | Authentic Tosa Knives in Australia

    When people hear the words Japanese knife, they often think of exceptional craftsmanship, outstanding performance, and a tradition that has been passed down through generations.

    Authentic Tosa knives represent that tradition through centuries of craftsmanship, combining the skills of experienced Japanese blacksmiths with techniques that continue to be handed down today.

    Unfortunately, not every knife marketed as a “Japanese knife” today truly reflects that heritage.

    After working as a chef in both Japan and Australia for more than 25 years, I came to appreciate how much difference a well-crafted knife can make. A great knife is far more than just a kitchen tool—it becomes an extension of the chef’s hand, making every cut more precise, enjoyable, and effortless.

    Along the way, I also became aware of another reality.

    Japan is home to many highly skilled blacksmiths who continue to forge exceptional knives using techniques that have been refined and handed down over generations. Yet much of their work remains relatively unknown outside Japan.

    At the same time, many products sold internationally as “Japanese knives” are mass-produced and have little connection to the craftsmen, traditions, and regional heritage that made Japanese blades respected around the world.

    I believed there should be a way to change that.

    That belief became Asaoya Yaichi.

    Our mission is simple:

    To bring authentic handcrafted Tosa knives from Japan to chefs, home cooks, and collectors throughout Australia.

    Every knife we offer is carefully selected through trusted relationships in Tosa, one of Japan’s most respected knife-making regions. Rather than focusing on quantity, we focus on authenticity, quality, and the people behind each blade.

    For us, every knife tells a story.

    Every hammer strike, every sharpened edge, and every finished blade represents years—often generations—of dedication, experience, patience, and pride.

    Our goal is not simply to sell knives.

    We want to help preserve Japan’s traditional blacksmithing culture by connecting Australian customers with the craftsmen behind these remarkable blades.

    By choosing an authentic Japanese knife, you are not only investing in a tool of exceptional quality—you are also helping support a tradition that deserves to be appreciated and carried into the future.

    Looking ahead, our vision goes even further.

    We hope to see Japanese blacksmiths receive the recognition they truly deserve—not only for the quality of their work, but for the generations of skill, dedication, and craftsmanship behind every blade.

    Our dream is to help create a future where handmade Japanese knives are appreciated around the world in the same way people admire fine Swiss watches, luxury leather goods, or handcrafted works of art. When the true value of craftsmanship is recognised, we believe more young people will be inspired to become blacksmiths, helping preserve this remarkable tradition for future generations.

    In this blog, we will gradually share stories and information about:

    • The history and appeal of Tosa knives
    • The knife-making culture of Shikoku and Tosa
    • The features of the knives we personally select and offer
    • The differences between knife steels
    • How to choose the right Japanese knife
    • Knife care and maintenance
    • The enjoyment of using authentic Japanese knives in Australia

    We hope to share the appeal of Tosa knives and the spirit of the craftsmen behind them as carefully and honestly as possible, while valuing each connection, each meeting, and each lesson we learn along the way.

    Whether you are a professional chef, a passionate home cook, or someone who simply appreciates genuine craftsmanship, we warmly welcome you to join us on this journey.

    Thank you for visiting Asaoya Yaichi.
