Toyotomi Hideyoshi's Sword Hunt of 1588 and the Separation of Samurai and Farmer: How Social Revolution Transformed Sword Distribution, Production, and Craftsmen

What Was the Katanagari Edict — The Precise Content of the 1588 Law

On July 8, 1588 (the 16th year of Tensho), Toyotomi Hideyoshi issued the "Katanagari Edict." While textbooks often describe it simply as "confiscating swords from farmers," the actual content of the decree was more complex and limited in scope.

The decree's main provisions can be summarized in three points.

1. Farmers (peasants) were prohibited from possessing weapons such as katana, wakizashi, bows, spears, and firearms.
2. Hideyoshi declared that the confiscated weapons would be used as casting materials for the Daibutsu (Great Buddha) at Hokoji Temple, which he was planning to construct (under the guise of saving farmers through the merit of Buddha).
3. The decree emphasized that farmers would prosper, and their descendants would prosper, by devoting themselves exclusively to agriculture.

Notably, the decree was not intended to eliminate swords throughout the nation. Samurai warriors were still permitted to wear katana, and what was prohibited was the possession of weapons by farmers, monks, townspeople, and other non-samurai classes. The Katanagari Edict was about the status-based monopolization of sword ownership—determining "who could possess swords"—rather than reducing the total number of swords in existence.

The Institutionalization of Soldier-Farmer Separation — The Social Transformation Completed by the Katanagari Edict

The Katanagari Edict did not emerge in isolation but was part of a series of social order-building policies coordinated with the "Sotabujierei" (Decree for Universal Peace) of 1585 and the "Kaizoku Teishi Rei" (Decree Stopping Piracy) of 1588.

Before this, during the Sengoku period, peasants would arm themselves and repeatedly stage collective uprisings such as "dochikki," "kunichikki," and "Ikko-ikki," with the social boundaries between samurai and peasants remaining fluid. There were cases, such as the Kaga Ikko-ikki (1488–1580), where peasants and monks maintained armed regimes for nearly 100 years.

The Katanagari Edict established a legal dichotomy: "samurai = permitted to wear katana; farmers = prohibited from wearing katana." This distinction became the foundation of the Edo period's shi-no-ko-sho (samurai-farmer-artisan-merchant) hierarchy. Katana-wearing as a marker of status—the cultural practice of samurai visibly displaying their status by wearing katana—acquired systematic significance after the Katanagari Edict.

Impact on Sword Production — The Reorganization of Market Structure

What changes did the Katanagari Edict bring to the production and distribution structure of Japanese swords?

During the Sengoku period, demand for swords was driven not only by samurai but also significantly by local magnates, wealthy farmers, and rural samurai in farming villages. For rural communities to arm themselves with katana, spears, and bows for self-defense was a normal "village defense cost."

After the Katanagari Edict, this rural demand for armed weaponry rapidly disappeared. In particular, the distribution channels for uchigatatana and wakizashi to rural areas were severed, and the market for low-priced "kazuuchimono" (mass-produced inexpensive swords) shrank. The sword market rapidly transformed into an exclusive market directed at the samurai class.

On the other hand, the prestige and artistic value of katana as symbols of samurai status became increasingly emphasized, and demand grew for high-quality swords intended for appreciation and ceremonial use. As the Toyotomi and Tokugawa governments consolidated their authority, the "goyou-toukou" (official swordsmith) system was established, where shoguns, daimyo, and hatamoto commissioned master swordsmiths to create katana, raising the social status of swordsmiths.

The Fate of Confiscated Swords — The Reality of the Great Buddha Casting Theory

The Katanagari Edict explicitly stated that confiscated weapons would be used for "nails and clamps for the Daibutsu at Hokoji Temple." However, historical evidence for whether the swords actually collected from peasants across the country were directly used in casting the Great Buddha is limited.

Records remain of reports submitted by local magistrates regarding the implementation of the confiscations, but primary sources detailing the quantities confiscated, their quality, or subsequent handling are sparse. According to research by medieval historians, the actual implementation of the sword confiscation varied by region: it was thorough in areas under direct daimyo control, but in mountainous regions and remote islands, implementation was often merely formal.

Many of the swords possessed by farmers were crude articles as "extensions of practical agricultural tools" and likely included items of different quality than the "Japanese swords" circulated as products by the sword industry.

Impact on Swordsmith Management — Changes in Demand Structure

Shortly after the Katanagari Edict, during the Bunroku and Keicho periods (1590s to early 1600s), large-scale military demand from the Korean campaigns (the Bunroku and Keicho campaigns of 1592–1598) coincided with a temporary surge in sword demand. Military mobilization reached 150,000 to 160,000 troops, and weapons procurement demand reached unprecedented levels.

However, when warfare ended with the Battle of Sekigahara in 1600 and the Summer Campaign of Osaka in 1615, military demand declined sharply. Swordsmiths were forced to shift the focus of their production from "swords for warfare" to "swords as symbols of peaceful samurai society."

This transformation was also a factor in creating the conceptual distinction between "shintou (swords made after Keicho)" and "koutou (swords made before Keicho)." The shift in sword evaluation from "reliability in actual combat" to "aesthetic quality of the jihada and hamon, and the swordsmith's reputation" is inseparable from the series of pacification processes: the Katanagari Edict → soldier-farmer separation → the Genwa Edict (1615).

Impact on Distributors — Specialization of Sword Merchants and Market Narrowing

During the Sengoku period, sword distribution was a multilayered market with peddlers, markets (ichi), and sword shops coexisting. Farmers, merchants, and temples also participated in sword transactions, but after the Katanagari Edict, buyers were limited to the samurai class.

This "narrowing of customers" was a double-edged sword for sword distributors. While the number of customers declined dramatically, the remaining customers (samurai) began to demand high-quality, high-priced swords, and the transaction value per deal increased. This period saw the professionalization and upscaling of sword merchants, and sword shops began to concentrate in major cities like Kyoto, Edo, and Osaka.

The Legacy of the Katanagari Edict — Continuity with Modern Sword Regulation

The Katanagari Edict was the first comprehensive legal regulation regarding the social positioning of Japanese swords. The idea that the state determines "who can possess swords" is the origin of "legal regulation of swords," which extends from the Meiji Sword Abolition Edict (1876) to the modern Swords and Firearms Possession Control Law (Gun and Sword Law).

In modern Japan, possessing and selling Japanese swords requires registration with the education board, and possession of unregistered swords is illegal. The starting point of the concept that "owning a sword requires a legitimate reason and proper procedures" lies in the social norm established by the 1588 Katanagari Edict that "only specific social classes can possess swords."

For the sword industry, the Katanagari Edict was not merely a historical event but a systemic transformation that became the distant cause of the modern market structure (demand limited to martial arts, artistic, and collecting purposes). The disappearance of the rural low-price sword market at that time is positioned at the origin of today's brand image of "Japanese swords = special possessions."
