Shoudai-yaki (小代焼) is a ceramic ware produced in the northern part of Kumamoto Prefecture, including Arao City, Nankan Town, and Kumamoto City, with origins dating to 1632. The craft is also written as 小岱焼, and both spellings are considered correct. Shoudai-yaki was designated as a Traditional Craft Product by the Minister of Economy, Trade and Industry on March 17, 2003. As part of the broader tradition of Japanese ceramics, it represents one of Kyushu's enduring folk pottery lineages.
History
Shoudai-yaki originated in 1632 (Kan'ei 9) when Hosokawa Tadatoshi, who had been transferred from Buzen, brought potters from the Meikoji family — first-generation Genshichi — and the Katsuragi family — first-generation Hachizaemon — and had them fire ceramics by order of the domain lord. The ware became known for its practical qualities and was historically referred to as Gotoku-yaki (Five-virtue ware) because it was said to possess five virtues: it does not spoil, does not transfer raw smells, does not attract moisture, neutralizes poison, and promotes longevity.
Following the Meiji Restoration, Shoudai-yaki experienced a period of decline due to competition from established porcelain-producing regions such as Seto and Arita. The tradition was subsequently revived during the Showa era through the efforts of Chikashige Jitaro and Shojima Heijiro. After World War II, several kilns were established at the foot of Mt. Kodai (Kodaisan), consolidating the craft's regional identity in Kumamoto Prefecture.
Techniques & Production Process
Shoudai-yaki is characterized by deep-colored glazes and dynamic surface patterns created through a traditional technique known as nagashi-gake (pouring glaze). In this method, glaze is poured or trailed over the ceramic surface, producing fluid, expressive patterns that vary with each firing. This approach gives individual pieces a distinctive, unrepeatable character associated with Japanese folk pottery traditions. Related Kyushu folk pottery traditions employing comparable rustic sensibilities include Koishiwara-yaki from Fukuoka and Agano-yaki, also from Fukuoka.
How to Identify Shoudai-yaki
Shoudai-yaki can be identified by its deep-colored glazes and the fluid, dynamic patterns produced by the nagashi-gake (pouring glaze) technique. Historical examples include tokkuri (sake flasks) dating from the late 17th to early 18th century, which demonstrate the characteristic glaze movement associated with the tradition. The overall aesthetic reflects the utilitarian origins of the ware as domain-commissioned folk pottery. Collectors and enthusiasts may also encounter pieces under the alternate spelling 小岱焼, which denotes the same ceramic tradition.
The Craft Today
Shoudai-yaki holds the status of a nationally designated Traditional Craft Product, a recognition conferred on March 17, 2003. Production continues in the northern Kumamoto region, centered on Arao City, Nankan Town, and Kumamoto City, with kilns established at the foot of Mt. Kodai. The craft exists alongside other Kumamoto ceramic traditions, including Amakusa Toujiki, another designated traditional craft from the prefecture. Shoudai-yaki items are among those represented at Densan Aoyama Square, the Tokyo showroom operated by the General Foundation for the Promotion of Traditional Craft Industries, located at 8-1-22 Akasaka, Minato-ku, Tokyo, and open from 11:00 to 19:00 throughout the year except during the New Year holiday period.
