Seto-yaki is a general term for the ceramics produced around Seto City in Aichi Prefecture, and together with Tokoname-yaki it is counted among Japan's Six Ancient Kilns. Its origins trace back to the late 5th century, to the production of sue ware at the Sanage kilns in what is now the Higashiyama hills of Nagoya City, and by the end of the 12th century Seto had begun producing 'Old Seto' ware - the only Japanese region to continue firing glazed pottery throughout the medieval period. In the Bunka era of the late Edo period (1804-1818), Kato Tamikichi introduced porcelain-making techniques from Hizen Arita, and sometsuke porcelain, painted with cobalt pigment, developed from there; from then on, traditional 'hongyo-yaki' pottery and 'sometsuke-yaki' porcelain were produced side by side. Blessed with high-quality kibushi and gairome clays, Seto-yaki is known for its white, low-iron body, and its products range from everyday tableware to fine art pieces. It is also the origin of 'setomono,' the word used across Japan to mean pottery in general, and was certified as a Japan Heritage site in 2017. Nationally designated Traditional Crafts include Akazu-yaki (1977) and Seto Sometsuke-yaki (1997).
Origin
The origins of Seto-yaki are said to trace back to the late 5th century, to the production of sue ware at the Sanage kilns in what is now the Higashiyama hills of Nagoya City. By the end of the 12th century, the Seto area had begun producing its own glazed pottery, developing into the only region in medieval Japan to continue firing glazed wares. Products of this era, known as 'Old Seto,' were distributed across the country as Buddhist ritual objects and everyday items, including four-eared jars and heishi bottles.
History
During the Kamakura and Muromachi periods, in addition to mass-produced yamajawan bowls, wares with iron glazes and decorative patterns spread throughout Japan. In the Bunka era of the late Edo period (1804-1818), Kato Tamikichi studied porcelain-making techniques in Hizen Arita and brought them back to Seto, and full-scale production of sometsuke porcelain using cobalt pigment began. From then on, traditional pottery was called 'hongyo-yaki' and porcelain 'sometsuke-yaki,' with Akazu-yaki designated a national Traditional Craft in 1977 and Seto Sometsuke-yaki in 1997.
Features
Seto is blessed with high-quality kibushi and gairome clays that contain almost no iron, and its products make the most of their beautiful white body. Akazu-yaki is known for its versatility, using seven kinds of glaze - including ash, iron, and Oribe glazes - together with twelve decorative techniques, while Seto Sometsuke-yaki is distinguished by its delicate cobalt-blue painted patterns. The nationwide use of 'setomono' to mean pottery reflects just how widely Seto's wares once circulated as a major production center.
