諸藩のお抱え刀工制度
Throughout the Edo period, the daimyo of the various domains retained skilled smiths as "o-kakae kaji" (domain-retained smiths), maintaining and advancing swordmaking within their territories. Standing alongside the shogunal official-smith system as a pillar of early-modern sword production, this institution—exemplified by Sukehiro's patronage under the Osaka castle warden and Naotane's retention by the Yamagata domain—stabilized the livelihoods of master smiths and sustained regional sword culture.
Description
What the Retained-Smith System Was
During the Edo period, the daimyo of the various domains retained skilled smiths within their territories, granting them stipends as exclusive swordmakers. These were called "o-kakae katanakō" or "o-kakae kaji" (domain-retained smiths). Whereas the shogunate maintained an official-smith system of its own direct smiths, each domain independently secured its own retained smiths to maintain military preparedness and preserve technical standards. For the smith it meant a stable stipend and secure status; for the domain it meant enclosing skilled artisans so they could not be lost to rivals.
Concrete Examples
Examples of retainer patronage are numerous. Tsuda Echizen-no-kami Sukehiro became a retained smith of the Osaka castle warden Aoyama Munetoshi in Manji 1 (1658), supporting the flourishing of Osaka Shintō. In the late Edo period, the Shinshintō master Daikei Naotane was retained by the Akimoto house of the Yamagata domain in Dewa in Bunka 9 (1812). Thus domain patronage continued to serve as a foundation for the work of master smiths from the Shintō period through the Shinshintō period of the bakumatsu.
The Link to the Kyōhō Sword Revival
The eighth shogun Tokugawa Yoshimune ordered daimyo across the provinces to report skilled smiths in their territories, seeking to revitalize the world of swords. This Kyōhō sword-revival policy dovetailed with the domains' efforts to identify and retain able smiths, encouraging the maintenance of regional swordmaking culture. As shogunal policy and domain patronage complemented one another, the tradition of swordmaking was preserved nationwide even in an age of peace.
Sustaining Regional Sword Culture
The retained-smith system became the foundation sustaining the sword traditions of regions such as Kaga, Satsuma, and Hizen. Because domains protected their retained smiths, regional production centers and styles could survive with their own distinctiveness even as sword production tended to concentrate in the centers of Osaka, Edo, and Kyoto. The smiths of each domain produced presentation blades for their lords and gift swords accompanying the sankin-kōtai, carrying out swordmaking bound up with the authority of the domain.
From the Bakumatsu to the Modern Era
In the bakumatsu, demand for retained smiths temporarily rose amid the drive to strengthen domain armaments, but the abolition of the domains (haihan-chiken, 1871) and the Sword Abolition Edict (haitōrei, 1876) after the Meiji Restoration destroyed the institutional basis of domain patronage. Many smiths who lost their patrons were forced to close their forges, yet the regional swordmaking skills they had maintained under domain protection were handed down as a foundation for the sword revival of the modern era and beyond.
Characteristics of This Era
- The o-kakae kaji system, in which daimyo retained skilled smiths on stipend
- Its position as a pillar of early-modern sword production alongside the shogunal official-smith system
- Concrete cases such as Sukehiro under the Osaka castle warden (1658) and Naotane under the Yamagata domain (1812)
- The maintenance of regional swordmaking culture in concert with the Kyōhō sword-revival policy
- The loss of its institutional basis through the abolition of domains and the Sword Abolition Edict, and the transmission of its skills into the modern sword revival
