Sword Appraisal Culture in the Bunka-Bunsei Era (1804-1829): How the Art of Judging Blades Spread from Samurai to Townspeople

Sword Society in the Bunka-Bunsei Period—The End of the "Era of Peace" and a New Gaze Upon Swords

The Bunka period (1804–1818) and Bunsei period (1818–1830) of the late Edo era represented an age positioned at the tail end of political stability, yet marked by the beginning of major economic and cultural shifts. The tightening brought about by Matsudaira Sadanobu's Kansei Reforms (1787–1793) had reached a conclusion, and the chōnin culture known as "Kasei culture" flourished.

The sword world too encountered an important turning point in this period. On one hand, the revivalist movement of shinshintō (new swords), which traced its origins to Suishinshi Masahide, accelerated, bringing forth successive swordsmiths who sought to reproduce the beauty of kotō theoretically and practically. On the other hand, the act of "viewing" swords—that is, the culture of authentication and appreciation—ceased to be the exclusive domain of the warrior class and began to spread among wealthy merchants and literati.

These two currents stood in a mutually complementary relationship. High-quality examples of shinshintō cultivated the eyes of sword enthusiasts, while the existence of sword enthusiasts elevated the creative drive of swordsmiths.

The Honami Household and the Commercialization of Authentication Certificates—The Marketization of Authority as "Honigaki"

During the Edo period, the supreme authority in sword authentication was the Honami household. Positioned as official appraisers to the Tokugawa shōguns and the various han domains, the Honami issued documents known as "honigaki" (true signatures) inscribed on folded papers (origami) or on the sheaths (saya-gaki) of blades. These functioned as official documents guaranteeing the authenticity and quality of swords.

During the Bunka-Bunsei period, demand for the Honami household's authentication certificates expanded sharply. Not only warriors but also merchants and wealthy farmers began to own swords as family treasures, seeking authentication certificates as proof of value. The Honami household expanded its appraisal operations in response, and "origami-certified" swords became established as a distinct market category.

That the phrase "origami-certified" persists in modern Japanese as meaning "approval for trustworthiness" reflects the historical fact that the Honami household's authentication certificates became widely embedded in society during this era.

However, this commercialization also generated criticism. In some quarters, disparities in the quality of authentication certificates became problematic, and cynical remarks such as "if you pay, you get an origami certificate" were heard. The "credibility problem of authentication certificates" that recurs in the modern appraisal industry had already begun to sprout during this period.

The Proliferation of Sword Literature—The Democratization of Knowledge and the Birth of "Toshinkai"

Another hallmark of the Bunka-Bunsei period was the mass publication of books and illustrated works on swords. Thanks to mature woodblock printing technology and rising literacy rates, numerous sword commentary works were published at price points accessible to commoners.

Representative examples include works that systematized warrior sword knowledge, and illustrated guides to sword characteristics organized by school and region, known as "tōkō meikan" (swordsmith signature catalogues). These works appeared from sword dealers' storefronts to lending libraries, read not only by warriors but also by curious townspeople.

A distinguishing feature of publications from this period was the abundance of visually descriptive content with illustrations explaining the characteristics of jihada, hamon, and tangi. Rather than mere lists of swordsmiths, practical authentication knowledge was conveyed, such as "works by this smith have these particular characteristics."

The proliferation of such works gave rise to a new social category: the "toshinkai" (sword enthusiast). These were individuals who collected and appreciated swords as a hobby—neither swordsmiths nor sword dealers. While such figures had long existed in warrior culture, during the Bunka-Bunsei period they spread to merchant classes, becoming the direct prototype of today's collector culture.

Toshinkai Salons and "Appreciation Gatherings"—Swords as Cultural Spaces Connecting People

During the Bunka-Bunsei period, sword appreciation gatherings were regularly held in Edo, Osaka, and Kyoto. Unlike what would later be called "sword exhibitions," these were cultural meetings aimed at sharing knowledge and taste rather than commerce.

Participants were a mix of warriors, wealthy merchants, and literati who displayed their brought swords and critiqued one another's collections. Leading swordsmiths like Suishinshi Masahide sometimes participated, and venues where appraisers, swordsmiths, and sword enthusiasts sat together and debated came to function as a form of literati salon.

Such gatherings fostered direct exchange between shinshintō swordsmiths and sword enthusiasts. Swordsmiths did not merely forge swords to commission, but articulated their own aesthetic sensibilities and creative philosophies, thereby cultivating the aesthetic judgment of enthusiasts. Meanwhile, feedback from enthusiasts influenced the swordsmiths' production in a virtuous cycle.

Suishinshi Masahide and Bunka-Bunsei Sword Theory—"Come to Know the Beauty of Kotō"

The figure who epitomized this period was Suishinshi Masahide (1750–1825). While he excelled as a swordsmith in practical execution, his influence as a sword theorist on posterity was even greater.

Masahide's works, such as "Tōken Jitsuyō-ron" and "Kenma Yosetsu," were pioneering achievements that analyzed the beauty of kotō scientifically and theoretically. These treatises, which systematically discussed the organization of jihada, the principles governing the formation of hamon, and the properties of whetstones, were widely read during the Bunka-Bunsei period and provided a common knowledge foundation for swordsmiths, polishers, and sword enthusiasts alike.

The social significance of Masahide's sword theory lay in the connection between "the technique of forging swords" and "the knowledge of appreciating swords" as a common language. Through this connection, sword authentication transformed from pure craftsman's intuition into something that could be, to a considerable degree, verbalized and logicized. This directly connects to the foundation of modern sword authentication education.

What the Bunka-Bunsei Period Left Behind—Continuity with Modernity

Much of what the Bunka-Bunsei period's sword culture bequeathed to the modern age remains. Certificate culture, the tradition of toshinkai salons, the literarization of sword theory—all of these stand as the direct ancestors of the modern Japanese sword industry, appraisal profession, and collector culture.

The examination system of the modern NBTHK (Society for Preservation of Japanese Art Swords) can be seen as the contemporary continuation of the Honami household's origami system. Moreover, the culture of "sword appreciation societies" where sword enthusiasts gather regularly to share information is in direct continuity with the salon culture of the Bunka-Bunsei period.

From a historical perspective, rather than disappearing with the dissolution of warrior society, the sword culture of this period—which acquired new practitioners in merchants, traders, and literati—represents the first turning point in the transformation of the Japanese sword from a "weapon" into a "cultural property."
