The History of Japanese Sword Dealer Guilds: From Edo-Period Kabunakama to Modern Industry Self-Regulation

Sword Shops and the Beginning of Commerce in the Edo Period

Japanese swords have been bought and sold since ancient times, but it was during the Edo period that "katanaya" (sword merchants) became established as a clear profession in society. In the peaceful world of the Edo period, swords were no longer purely combat tools, but came to hold multifaceted value as status symbols for samurai, tools of etiquette, works of art, and investment objects. This diversification in demand facilitated the establishment of the sword merchant profession.

Edo-period sword merchants could be roughly divided into two types. One type was the "goyou katanaya" (official sword merchants) who procured swords within specific master-servant relationships as purveyors to the shogunate and daimyo houses. The other type was "machi katanaya" (town sword merchants) who served samurai and wealthy merchants in the city. Numerous sword merchants lined the streets of Edo, Osaka, and Kyoto, with sword merchant quarters forming particularly around the Nihonbashi area of Edo and the Sakaishin area of Osaka.

The business of sword merchants went beyond simple buying and selling. They also handled polishing, production of fittings (koshirae), repair of scabbards (saya), and trade-ins, functioning as comprehensive service centers for all matters related to swords. For samurai and wealthy merchants who were customers, building ongoing business relationships with trustworthy sword merchants was important in avoiding the risk of acquiring counterfeits and gaining the assurance of being able to sell or trade for new swords when needed.

Formation of Trade Guilds—The "Kabunakaima" System

One of the important institutions in the economic policy of the Edo shogunate was the "kabunakaima" (guild or trade association). A kabunakaima was a merchant association formed by members of the same trade under the approval of the shogunate, and members who joined the kabunakaima paid a certain fee (tax) to the shogunate in exchange for the recognition of their exclusive right to conduct business in a specific trade.

Sword merchants also became the subject of this kabunakaima system, and sword merchants in Edo organized the "sword merchant kabunakaima." The main functions of the kabunakaima were as follows.

• Price control: Setting upper and lower price limits for sword purchases and sales to prevent excessive price falls and excessive profits
• Quality control: Mutual surveillance to prevent the circulation of false signatures and counterfeits, and the obligation to report to wholesalers
• Regulation of new entrants: Excluding businesses without guild membership from engaging in business and protecting the profits of existing members
• Dispute resolution: Resolving troubles between members internally, thereby reducing litigation before the magistrate's office

The functions of the kabunakaima were not merely for protecting the vested interests of existing merchants, but also functioned as a mechanism to prevent buyers from being unfairly disadvantaged in an industry dealing in swords, a product for which distinguishing genuine from fake is difficult. Guild membership was also evidence of earning the trust of fellow members of the industry, and it is believed that guild merchants gained more customer trust than unaffiliated merchants.

The Honami Family and Their Relationship with the Sword Industry

The greatest authority in the sword industry was the "Honami family," which reigned as the head house of appraisers and polishers. The Honami family was granted the authority by the shogun's house to issue appraisal certificates (orisashi), and wielded tremendous influence in determining the authenticity and value assessment of swords.

The sword merchant kabunakaima valued their relationship with the Honami family and made it customary to attach a Honami orisashi certificate to any major sword sale. The presence or absence of an orisashi certificate significantly affected sword prices, and it was not uncommon for swords with certificates to command prices more than double the usual price. This practice became the prototype of the modern "NBTHK (Nippon Bijutsu Touken Hozon Kyokai, or Society for the Preservation of Japanese Art Swords) certificate of examination" system.

The appraisals of the Honami family were based on experience and transmitted knowledge passed down through generations, and were the most authoritative evaluation standard of the time. For sword merchants, maintaining good relations with the Honami family was an indispensable element in demonstrating to customers the trustworthiness of the swords they handled. This structure shares the modern approach of ensuring trust through the involvement of a third-party expert appraisal in transactions.

The Tenpo Reforms and the Dissolution and Reorganization of Guilds

In the later Edo period, during the Tenpo Reforms (1841–1843), Chief Councillor Mizuno Tadakuni blamed guild organizations as a cause of soaring prices and issued an order for the dissolution of kabunakaima. The sword merchant kabunakaima was forced to dissolve temporarily, but the results of free competition did not necessarily bring about lower prices. Rather, it led to market confusion and the proliferation of fake and low-quality swords.

In 1851 (Kaei 4), the shogunate approved the revival of the kabunakaima, and sword merchants reorganized their guild. This turn of events was an important occurrence that established in the shogunate the recognition that industry self-regulation (trade associations) was essential for quality control and the maintenance of market order.

This series of events demonstrates that in the case of products like swords, for which it is difficult to judge authenticity and value without expert knowledge, voluntary agreements and mutual surveillance among merchants played a certain role in protecting the interests of both buyers and sellers. The lesson that the mere introduction of simple free competition could instead lead to the spread of shoddy products and fraudulent transactions is thought to have influenced later approaches to industry organizations.

Transitions in Industry Organizations After the Meiji Era

The Meiji Restoration (1868) and the Sword Abolition Edict (1876) dealt a devastating blow to the sword industry. Demand declined sharply, and many sword merchants went out of business. However, demand for swords as works of art and antiques remained, and surviving sword merchants made a fresh start as "art sword merchants."

From the late Meiji period through the Taisho period, sword merchants in various regions began reorganizing themselves as voluntary trade associations. During the Showa period, organizations that would become the predecessors of the "All Japan Sword Merchants Business Cooperative Association" were put in place, and as the postwar sword revival progressed, association activities became more active.

The current "All Japan Sword Merchants Business Cooperative Association (Zen Tosho)" carries out the following activities as the representative organization of the industry.

• Guidance and promotion regarding the appropriate distribution of registration certificates
• Sponsorship and organization of sword markets and exhibitions
• Establishment of guidelines for responses to foreign buyers
• Cooperation with the Agency for Cultural Affairs and the National Police Agency in measures against counterfeit and smuggled goods

What these activities have in common is the stance of supporting, through the framework of the industry as a whole, tasks that cannot be adequately handled by the efforts of individual sword merchants alone—such as distinguishing genuine from fake, compliance with relevant laws and regulations, and communication with overseas customers. Sword merchants who are members of the association are in a position to access information and training opportunities that would be difficult to obtain independently through such a shared foundation.

Modern Significance of Industry Self-Regulation

An especially important contemporary issue for which industry self-regulation of the sword trade has come to the fore is the management of distribution on the Internet. The buying and selling of unregistered swords through second-hand marketplaces and auction sites, inappropriate sales to foreigners, and the circulation of false signatures and false appraisal certificates are becoming problematic issues, and strengthened capacity for response by the association has become urgent.

As of 2026, the expansion of cross-border e-commerce has led to an increasing trend in online sales of Japanese swords to overseas buyers. The role of industry organizations that support legitimate online sword transactions carried out through proper procedures will only become more important in the future.

The function of "market order maintenance" that the Edo-period kabunakaima fulfilled remains the most important role that industry organizations should play today. For the buying and selling of Japanese swords, a special cultural asset, to be conducted appropriately, both legal regulation and industry self-regulation are essential.

Things to Check When Purchasing Swords

Swords are products that require specialized knowledge, so for readers considering a purchase, verifying what backing the transaction partner has can provide assurance.

• Membership status in industry organizations: Whether a sword merchant is a member of industry organizations such as the All Japan Sword Merchants Business Cooperative Association is one indication
• Presence or absence of an appraisal certificate: Check whether an appraisal certificate issued by an examination body such as the NBTHK (Nippon Bijutsu Touken Hozon Kyokai) is attached
• Verification of registration certificate: Swords normally come with a registration certificate, and verify that the details in the registration certificate match the actual sword
• Explanation and consultation system: Check whether you can receive specific explanations from staff regarding provenance and condition, and whether there is a consultation window available after purchase

These verification procedures can be said to be a substitution of the role of "guaranteeing trustworthy transactions" that Edo-period kabunakaima fulfilled for the work that modern consumers themselves must proactively undertake. Industry self-regulation and information provision by industry organizations aims to serve as an aid in providing such judgment materials.
