Owari Seki — Mino Swordsmiths Who Migrated to Owari Province

Historical Background

Mino Province (present-day Gifu Prefecture) flourished during the Sengoku period as a major production center for mass-produced swords, and smiths based in Seki supplied blades across Japan. As national unification progressed and wartime demand settled, smiths of Mino began to move their base to the castle towns of powerful daimyo. Migration to Owari began in earnest during the Keicho era (1596–1615), especially in Keicho 15 (1610), when construction of Nagoya Castle began, and around Keicho 17 (1612), when the castle town was laid out.

The castle town that formed around Nagoya Castle became home to the retainers of the Owari Tokugawa family (Owari domain, 620,000 koku), and demand for high-quality swords surged. To meet this demand, skilled smiths gathered from Seki in Mino Province, giving rise to a new sword-producing center, Owari Seki.

Characteristics of the Style

Owari Seki smiths built on the Mino tradition while incorporating elements of the Soshu tradition and the styles of the shinto period, developing a distinctive style. The hamon frequently used forms characteristic of the Mino tradition, such as suguha, gunome, and pointed gunome, and the jigane was mainly itame. From the shinto period, hamon consisting mainly of notare influenced by the Soshu tradition also came to be seen.

Representative Smiths

Masatsune had been signing his blades as Kanetsune while in Mino. In 1567 (Eiroku 10) he moved to Komaki in Owari, and later received the title “Sagami-no-Kami” and changed his name to Masatsune. Ujifusa and Nobutaka are also known as representative smiths of Owari Seki, each supplying favored swords to the warrior class of Owari.

Historical Significance

The existence of Owari Seki is an important example of how the technical lineage of the Mino tradition was passed down and transformed from the late koto period into the Edo shinto era. This swordsmith community formed in response to the specific warrior demand of the Nagoya castle town and concretely illustrates the process by which sword culture took shape in provincial cities. Blades attributed to Owari Seki are still visible today in sword museums and private collections, and serve as indispensable material for studying the regional development of the Mino tradition.
