Choosing Japanese Knives | Knowledge and Renowned Regions for Meeting a Lifetime Blade

Japanese knives are respected by chefs and kitchen enthusiasts around the world as the pinnacle of cutting tools. Their history traces back to the forging techniques of Japanese swords, and the craftsmanship honed over centuries lives in every single blade. Abroad, traditional Japanese knives priced over 50,000 yen sell out immediately, but in fact, if you purchase domestically in Japan, you can obtain knives of equivalent quality at far more affordable prices. This article conveys the knowledge you need to find a lifetime blade, from the basics of choosing a knife to characteristics of each region and recommendations based on budget.

The Difference Between Japanese and Western Knives — The World of Single-Bevel and Double-Bevel

The first step to understanding Japanese knives is knowing the difference between "single-bevel" and "double-bevel" designs. Most traditional Japanese knives are single-bevel, with only one side of the blade ground to a sharp edge. This structure produces an extremely beautiful cross-section on food items and enables the delicate cuts essential to Japanese cuisine, such as sashimi and vegetable slicing. Representative single-bevel knives include the yanagiba (blade length 21–33 cm) for drawing sashimi, the deba (blade length 15–21 cm) for filleting fish, and the usuba for cutting vegetables. Western knives, by contrast, are typically double-bevel, exemplified by chef's knives and paring knives. The santoku, most widely used in Japanese households, is a double-bevel all-purpose knife that merges the best of Japanese and Western traditions, handling meat, fish, and vegetables alike. For first-time Japanese knife buyers, starting with a santoku (blade length 16.5–18 cm) is recommended. The typical price range is 5,000 to 30,000 yen.

How Steel Type Affects Sharpness and Maintenance — Carbon Steel or Stainless Steel

The type of steel greatly influences a knife's performance. There are two main categories: "carbon steel" and "stainless steel." Carbon steel, represented by shiromi (white paper steel) and aogami (blue paper steel) from Yasuki steel, is prized for its razor-sharp edge and ease of sharpening. Shiromi No. 2 is easy to sharpen even for beginners, while aogami super maintains a remarkably long-lasting sharpness. However, carbon steel is prone to rust, so after use it must be immediately dried and stored in a dry place. Those who see this maintenance as a "joy of cultivation" will appreciate it. High-end stainless steels like VG10 (V-Gold 10) and SG2 (powdered high-speed steel) resist rust and require minimal maintenance. Recent technological advances have enabled stainless steel to approach the sharpness of carbon steel, making it the wise choice for those uncertain about maintenance. Additionally, "laminated" or "three-layer" construction, where a steel core is sandwiched between stainless steel, offers a practical option combining the best of both worlds.

Knowing the Character of the Three Major Regions — Sakai, Seki, and Echizen

Japanese knife-making centers are scattered throughout the country, but three regions are particularly renowned: Sakai, Osaka Prefecture; Seki, Gifu Prefecture; and Echizen, Fukui Prefecture. With 600 years of history, Sakai is the mecca of Japanese knives, with approximately 90% of professional chefs using Sakai blades. The division-of-labor system—where smithing, edge-grinding, and handle-fitting craftspeople push their skills to the limit—is the defining characteristic. For yanagiba knives, choosing Sakai is rarely a mistake. The professional-grade price range is approximately 20,000 to 100,000 yen. At Sakai's "Tower Knives Osaka" or "Sakai Blade Museum," you can hold and select knives in person. Seki is known as Japan's leading cutlery town, home to many manufacturers including Kai, maker of the globally recognized "Seki Magoroku" brand. The "Blade Festival" held every October in October draws over 200,000 visitors and offers 30–50% discounts off regular prices, making it an ideal opportunity for bulk purchases. Echizen forged blades carry 700 years of tradition, characterized by hand-forged aesthetics and practicality. The cutting edge born from the unique "ni-mai-hiroge" forging method is exceptional, and home-use santoku knives are relatively affordable at 8,000 to 20,000 yen.

Other Notable Regions and How to Choose a Specialty Shop

Beyond the big three regions, several others merit attention. Sanjo and Tsubame in Niigata Prefecture are major metal-processing hubs where brands like Fujitaro (TOJIRO) produce high-value-for-money knives. Santoku knives are available at 3,000 to 10,000-plus yen, making them ideal for a first purchase. Tosa forged blades from Kochi Prefecture are characterized by their unadorned appearance with blacksmith's finish (retaining oxidation patina), popular with those seeking powerful cutting performance for outdoor tools and hunting knives. Along with Tanegashima scissors from Kagoshima, be sure to stop by when visiting the Kagoshima area. When selecting a specialty shop, three points matter most. First, you can actually hold the knives. Second, staff can explain steel types and manufacturing processes in detail. Third, after-sales services like blade resharpening are available. In Tokyo, shops like Kamaasakashoten and Tubaya on Nishi-Asakusa Tool Street are trusted long-established names; in Kyoto, Aritsugu and Kichiichimoji are well-regarded.

Post-Purchase Care and Basic Sharpening

Once you have your lifetime blade, proper care will let you enjoy it for years to come. Most important is washing it with neutral detergent immediately after use and completely drying it. Never use a dishwasher, as it damages the blade. Store it so the edge won't strike anything—use a knife block, magnetic bar, or blade guard. A medium whetstone (around #1000 grit) is sufficient for home use. Maintain a 15–20-degree blade angle, applying pressure on the push stroke and releasing it on the pull—repeating this fundamental motion restores a professional-quality edge. Monthly or bimonthly sharpening is sufficient, but if you lack confidence, using a specialty shop in the region or department store sharpening service (approximately 500 to 2,000 yen per session) is a smart choice. Pay attention to the handle material as well. Magnolia wood is traditional for Japanese knife handles—lightweight and comfortable in hand—while rosewood and ebony offer elegance and durability. Western-style knives typically feature highly water-resistant materials like laminated wood or Micarta. Handle shapes include the oval, said to fit Japanese hands best, but you can choose according to preference, such as chestnut or octagonal shapes. Japanese knives transcend mere tools, existing as works of art. Visiting the region, hearing the craftspeople's stories, and holding and choosing your own blade with your own hands—that experience itself will deepen your affection for your knife many times over.
