Commissioning a Custom Japanese Sword: The Full Process from Client Consultation to Delivery

What Is Chuumonuchi? — Custom-Made Japanese Swords

Chuumonuchi (注文打ち) or chuumon-katana (注文刀) refers to a swordmaking style in which a tosshi (swordsmith) individually crafts a blade according to a client's specific requirements. Unlike purchasing mass-produced blades available in the market, with chuumonuchi the customer specifies the sword's specifications, and the tosshi forges an individual blade accordingly.

Modern sword sales follow two main paths. One involves tosshi freely creating blades and selling them through sword dealers; the other is chuumonuchi, where the tosshi works directly on commission from clients. The capacity to accept chuumonuchi commissions varies by tosshi, and for renowned tosshi, waiting periods of several years are not uncommon.

The First Consultation — What Should the Customer Decide?

When commissioning a chuumonuchi, the customer must communicate several basic specifications to the tosshi in advance.

Sword Type and Dimensions

The first decision concerns the type of sword. You must specify the blade type—tachi, katana, tanto, wakizashi, naginata, and so forth—along with desired measurements: blade length (hacho), curvature (sori), width at the base (motohaba), width at the point (sakihaba), and weight.

Some tosshi will propose dimensions after listening to customers who say "I'll leave it to your judgment," asking about their build, intended use, and preferences. Particularly for blades intended for actual use—such as in iaido—matching the dimensions to the user's arm length, physique, and their school's standard specifications is essential.

With or Without Koshirae (Mountings)

Decide whether to commission only the blade or the complete koshirae (mountings and fittings) as well. Koshirae includes the saya (scabbard), tsuka (grip), tsuba (hand guard), menuki (ornamental grip pegs), fuchi and kashira (collar and pommel), and habaki (blade collar), typically handled by specialized craftspeople (koshirae-shi, saya-shi, menuki-shi, etc.).

Including koshirae significantly increases costs, so budget planning must be clear from the start. Sometimes the tosshi handles only blade creation and refers you to craftspeople for the koshirae; other times the tosshi coordinates the entire project.

Hamon (Blade Pattern) Preferences

Discuss hamon style in advance as well. Communicate your preferences for classic hamon patterns: suguha (straight), gunome (wavy), choji (clove-shaped), notare (flowing), or hitatsuura (full-coverage), among others.

However, hamon is a natural result of the hardening process and does not emerge exactly as designed. The tosshi can indicate direction—"I aim for a hamon in the ○○ style"—but the finished blade's hamon may present an entirely different appearance. Customers must understand this variability when commissioning.

Material Selection

Choose whether to use tamahagane (traditional high-carbon steel), blend in foreign steel, or use entirely modern steel—material choice affects both price and quality. Some customers prefer "modern blades made exclusively with tamahagane," while others, considering budget, accept substitute materials in part of the construction.

Specification Documents and Contracts

The consultation details are typically formalized as a specification or swordmaking commission document. This records blade length, curvature, width, hamon direction, materials, koshirae details, estimated delivery timeframe, price, and advance payment (deposit) terms.

Paying a deposit (advance payment) is standard practice in chuumonuchi. Typically, 20–50% of the total price is paid before work begins to cover material costs (tamahagane) and initial labor. The remainder is settled upon delivery.

Production Timeline — How Long Will It Take?

Production timelines for chuumonuchi vary depending on the tosshi's workload, blade type, and koshirae complexity. General guidelines follow:

• Blade only (tanto, wakizashi): 3–6 months
• Blade only (katana, tachi): 6–12 months
• Complete with koshirae: 12–24 months or longer

For renowned tosshi or heavily commissioned craftspeople, waiting lists can extend several years. Additionally, production may take longer than scheduled due to material condition, hardening issues, or sori correction problems. When a tosshi requests more time, customers must remain patient and respect that judgment.

Witnessing Completion and Taking Delivery

After the blade is completed, the customer typically visits the tosshi's forge to receive it directly. At this time, the tosshi often explains the creative intent, the blade's hamon characteristics, and aspects of the work the tosshi particularly values.

The customer inspects the finished blade and consults with the tosshi if there are significant deviations from expectations. However, cases of "I dislike it, make it completely again" are rare; most often, customers trust the tosshi's judgment and accept the blade. This reflects a fundamental industry belief: "A sword is a collaborative work between tosshi and customer."

The True Value of Chuumonuchi — Dialogue with the Craftsperson

The greatest value of chuumonuchi lies in "dialogue." It offers communication with the craftsperson that mass-produced blade purchases cannot provide. By asking the tosshi to incorporate your commemorative dates, family crests, the sword's lineage, or life milestones, a truly unique blade is created.

Many customers deepen their understanding of Japanese sword-making processes and strengthen their appreciation for sword culture through the chuumonuchi experience. Chuumonuchi stands as the pinnacle of sword collecting, supported by enthusiasts both in Japan and internationally.
