Yamato no Kami Yoshimichi

Yamato no Kami Yoshimichi, Innovator of Ōsaka Shintō

Yamato no Kami Yoshimichi was a swordsmith active in Ōsaka, Settsu Province (present-day Ōsaka Prefecture), from the mid to late 17th century in the early Edo period. He is renowned as one of the master smiths who represent Ōsaka shintō. The Yoshimichi family began with the first Tanba no Kami Yoshimichi of Kyoto, whose second son moved to Ōsaka and established the “Ōsaka Yoshimichi.” Yamato no Kami Yoshimichi is said to have been the second son of this first Tanba no Kami Yoshimichi of Ōsaka. The distinctive hamon known as “sudare-ba” was originated by the first Tanba no Kami Yoshimichi of Kyoto, and the Yamato no Kami Yoshimichi line was also known for mastering it. This became the greatest hallmark of the Yoshimichi school. The name Yamato no Kami Yoshimichi was inherited over several generations, and the first and second generations are listed as wazamono in the Kaihō Kenshaku.

In the early Edo period, Ōsaka was the “kitchen of the realm” (tenka no daidokoro), a center of commerce and the economy. As a sword-producing region it developed into a major center rivaling Edo and Kyoto. Ōsaka smiths met the practical demand of the warrior class as well as the demand for swords as art objects and crafts, which was backed by a rich townsman culture, and they developed flamboyant and individual styles as if competing with one another. The sudare-ba born in Kyoto was inherited by the Ōsaka Yoshimichi family. It was an innovative hamon developed within this cultural environment of Ōsaka, and it is still highly regarded today as one of the most impressive inventions in Edo-period sword art.

Sudare-ba—The Greatest Invention of Edo Shintō

The greatest factor that made Yoshimichi’s name immortal is the creation of the distinctive hamon called “sudare-ba.” Sudare-ba is a hamon in which sunagashi appear in the blade as vertically continuous lines, like a hanging takesudare (bamboo blind), and it has a regular yet varied appearance. From a distance this hamon has a magnificent beauty. On close observation, a more complex and rich internal structure becomes apparent.

The technical characteristic of sudare-ba is that the clay application during quenching must be controlled with great precision and complexity, and it cannot possibly be realized without advanced skill. Making the elements of the hamon (the height, width, and inclination angle of gunome) vary while maintaining a certain regularity, and finishing the whole so that it forms a visually unified beautiful pattern, is a feat impossible for an ordinary smith. That Yamato no Kami Yoshimichi perfectly realized this difficult technique, refined and evolved it further, and passed it down to later generations can be said to be an epoch-making event in the history of Japanese swordsmithing technique.

The nie used in the hamon is large-grained, and “large-grained nie” appears distinctively. This nie shines splendidly when light falls on it, and together with the complex pattern of sudare-ba it produces an extremely visual effect. The nioi is deep, and its activity within the blade is abundant. The closer one observes, the more one can confirm a meticulous finish down to the details.

Jigane and Shape Characteristics

Yoshimichi’s jigane is mainly itame-hada, with ji-nie on well-forged, uniform jigane. It has the clear, bright jigane texture common to Ōsaka shintō, and it is characterized by a bright ground tone that brings out the splendor of sudare-ba. Chikei and ji-nie appear abundantly, and the contrast with the blade where nie is present is vivid.

As for blade shape, many have the typical shape of early Edo-period swords: wide mihaba, a full koshimoto, a small difference between moto and saki width, and chū-kissaki. Some have the shape peculiar to Ōsaka swords of the Keichō and Kan’ei periods, faithfully showing the development of sword styles in Ōsaka at that time. Yoshimichi’s characteristics are also displayed in wakizashi and tantō, which show a high degree of completion across various forms.

Historical Significance of Yoshimichi in Ōsaka Shintō

Ōsaka shintō is known as a production center that produced Inoue Shinkai and Tsuda Echizen no Kami Sukehiro, and it achieved a unique height in the art of the sword in the Edo period. Among them, Yoshimichi’s sudare-ba stands out as the most individual and innovative contribution. It won him a nationwide fame beyond that of a mere provincial smith.

Sudare-ba influenced later smiths. In the late Edo and bakumatsu periods, some shinshintō smiths also attempted hamon in the style of sudare-ba, which confirms that Yoshimichi’s creations had a long-term influence on the history of Japanese swords. Even today, modern smiths continue the challenge of reproducing sudare-ba, showing that the technical difficulty and aesthetic appeal of this hamon live on.

Yamato no Kami Yoshimichi at Tōken-za

Tōken-za presents Yamato no Kami Yoshimichi as the most innovative sword artist that Ōsaka produced in the Edo period. Yoshimichi’s contribution, which greatly expanded the aesthetic possibilities of Japanese swords through his unique sudare-ba, shows that the Japanese sword is both a thing that keeps its forms and a thing that renews its forms. For modern enthusiasts too, the visual beauty of sudare-ba is immediately understandable, and Yoshimichi’s swords have the power to strongly impress the artistry of the Japanese sword even on people seeing one for the first time.

Yoshimichi’s Signature and Identification by Generation

The signature of Yamato no Kami Yoshimichi reads “Yamato no Kami Yoshimichi,” and the same name was used over several generations. Works of each generation are appraised by subtle differences in the composition of the hamon, the quality of the jigane, the shape, and so on. By comparing and appraising works of each generation, one can trace the trajectory of the technical development of the Yoshimichi school, which is itself an interesting theme in Japanese sword research. The large-grained nie and complex sudare-ba pattern characteristic of Yoshimichi’s swords are important criteria for judging whether a piece is a shinsaku (authentic work). Because they demand precise observational discernment from researchers and enthusiasts, Yoshimichi’s works embody the high expertise of Japanese sword appraisal. The swords and wakizashi of several generations of Yoshimichi remain indispensable in discussing the achievements of Edo-period sword art.
