The 400-Year Appraisal Business of the Honami Family: Official Sword Appraisers to the Shogunate, Authentication Documents, and School Succession

What is the Honami Family——The House System of Japanese Sword Authentication

The Honami Family (Honami-ke) was a clan of official craftspeople in samurai society that specialized in polishing, wiping, and appraising Japanese swords. Rising in the mid-Muromachi period (15th century), they served as official appraisers to the Tokugawa shogunate throughout the Edo period, reigning over the sword world for over 400 years as the "absolute authority that determined the value of Japanese swords."

The Honami family was a collective name for the entire clan, though in reality there were multiple branches including the main house (Honami) and branch families (Koetsu, Motoyanagi, Tokiwa families, etc.). Among them, Koetsu (光悦) is famous as an artist, but behind this was the family business of the Honami family as connoisseurs of Japanese swords.

The Birth of Official Appraisers——From the Muromachi Shogunate to the Tokugawa Shogunate

The Honami family's position as official appraisers is said to have been established during the time of Ashikaga Yoshimitsu, the third shogun of the Muromachi shogunate. At that time, the shogun's family collected and managed many renowned swords, but needed specialists to officially evaluate the authenticity and value of Japanese swords. The Honami family met this demand and functioned as an officially recognized institution responsible for "appraising granted swords," "grading gifts," and "recording and managing renowned blades."

Even after the establishment of Tokugawa rule, the Honami family's position remained unshaken. The Edo shogunate regarded Japanese swords as the soul of samurai and symbols of authority, with renowned blades frequently exchanged as gifts between shoguns and daimyo. The Honami family monopolized the appraisals that were needed at such times: "What is the value of this sword?" and "Who is the maker?"

The compensation paid by the shogunate to the Honami family was called fuchi (扶持), an official stipend, and records remain of the shogunate granting them a feudal income as an official appraisal institution. This means the Honami family was not merely a private appraisal business, but was incorporated as public infrastructure within samurai society.

The System of Shōshin-gaki (Authentication Certificates)——How Appraisals Determined Value

The core of the Honami family's appraisal system lay in a document called a shōshin-gaki (正真書), an authentication certificate. A shōshin-gaki was an official authentication document issued by the Honami family that recorded "who made this sword and what is its value."

The shōshin-gaki recorded the following:

• Maker (swordsmith's name, school, period)
• Appraised value (dai (代): unit of currency)
• Description of shape and inscriptions
• Date of issuance and the Honami family's signature and seal

Particularly important was the notation of the appraised value called dai (代). In Edo-period dealings with renowned swords, "how many dai the Honami family appraised [a sword]" became the standard for pricing. For example, a sword written in a shōshin-gaki as "valued at 300 gold coins" would be traded based on that appraisal when it came to market. This system had the same function as an authoritative appraisal certificate for artworks today, and had the power to effectively control market prices.

The shōshin-gaki was kept and inherited together with the sword, and functioned as evidence of its provenance. The phrase "Honami's orikami (折紙)" persists in modern Japanese as an idiom meaning "reliable guarantee," demonstrating the considerable social influence of Honami appraisals.

Technical Transmission Through the House System——Training to Hone the Appraiser's Eye

The Honami family's technical transmission was carried out through the house system (iemoto-sei). The techniques of appraisal were transmitted from master to apprentice through oral tradition and practical instruction, with strict prohibition against external disclosure.

Those entering apprenticeship with the Honami family began first with polishing (togi). Through the process of polishing swords, they learned to recognize with hands and eyes the qualities of the steel, the characteristics of the jihada, and the patterns of the hamon. Next, they mastered "wiping" (nugui)——removal of oil and surface observation——before finally advancing to "appraisal" (mikiwame).

This training process took from several years to over a decade. Since scientific analytical equipment did not exist at that time, appraisal relied entirely on "the eye to see," "the hand to touch," and "the nose to smell." The ability to determine the school, period, and maker by synthesizing the nuances of the hamon, the color tones of the jihada, the subtle positioning of the shinogi-suji, the color of the rust on the nakago——could only be developed through years of accumulated experience.

Honami Koetsu and Japanese Sword Appraisal

Honami Koetsu (1558–1637) is known as an artist skilled in calligraphy, pottery, lacquerware, and maki-e decoration, but his foundation was as a Japanese sword appraiser for the Honami family. Koetsu received the land of Takagamine in the northern Kyoto area from Tokugawa Ieyasu and built an artist village (Koetsu Village), which also had his background as a sword appraiser. Koetsu's artistic eye was an extension of the connoisseurship needed to discern the "beauty" of Japanese swords.

The Honami Family After the Modern Era and Their Influence on Contemporary Appraisal

When samurai society was dismantled by the Meiji Restoration and the Sword Abolition Edict (1876), the Honami family's official position as court appraisers disappeared. However, the family business continued without decline, and as swords came to be re-evaluated as artworks, the Honami family's appraisal authority remained valid in the private market.

The modern Japanese sword appraisal organization, the "Foundation for the Preservation of Japanese Art Swords (NBTHK)," was established in 1948, and its appraisal philosophy and methodology strongly reflect Honami-school influences. The review systems for designations such as "Important Sword" and "Exceptionally Important Sword" can be said to be the modern continuation of the grading systems established by the Honami family.

Conclusion——The 400-Year History of the Honami Family Told by "Orikami"

As the phrase "orikami-zuki (折紙付き)" is established in modern Japanese, the concept of "appraisal of Japanese swords by an authoritative third-party institution" that the Honami family constructed over 400 years continues to live on as a fundamental value in the contemporary sword market.

The history of the Honami family is not merely a record of a craftsman's clan. It is a 400-year history that embodies the universal truth that for a thing like a Japanese sword to have "value" and circulate in a "market," there must be an authority to evaluate and guarantee it.
