About Shitoro Ware | A Representative Ceramic Producing Area of Shizuoka Prefecture
Shitoro ware (shitoroyaki) is traditional pottery fired in the Kanaya region of Shimada City, Shizuoka Prefecture. With a long history spanning from the Muromachi period, it is known as a renowned kiln that was beloved by tea master Kobori Enshu and counted as one of the “Seven Kilns of Enshu” (Enshu Shichiyou). It is characterized by deep brown and dark brown hues and rustic, powerful aesthetics, and is designated as a Shizuoka Prefecture local craft.
The Kanaya region of present-day Shimada City was once called “Shitoro-go,” and this place name became the origin of the pottery’s name. Located on the west bank of the Oi River, this region has long been blessed with high-quality ceramic clay and possessed an environment well-suited to pottery making.
History of Shitoro Ware | From the Muromachi Period to Modern Times
Origins and Establishment
There are multiple theories regarding the origins of Shitoro ware. The most plausible theory is the “Old Seto-style glazed pottery” origin theory, which states that pottery craftsmen from Seto migrated to the area and began firing during the Daiei era (1521-1528) in the late Muromachi period. During this time, under the rule of the Ashikaga clan, Seto techniques spread throughout various regions, and it is believed that full-scale ceramic production began in the Shitoro area.
However, there are traces of pottery-making in the Kanaya area from before the Muromachi period, and many ancient kiln sites have been discovered. These archaeological remains reveal that the tradition of ceramics was rooted in this region before Shitoro ware was established.
Kobori Enshu and the Seven Kilns of Enshu
Shitoro ware became nationally known in the early Edo period. Tea master Kobori Enshu (1579-1647), who served as the tea ceremony instructor to the third shogun Tokugawa Iemitsu, took notice of Shitoro ware and provided instruction in tea utensil production.
Kobori Enshu possessed a unique aesthetic sense called “kireisabi” (refined simplicity), and instructed kiln owners throughout various regions to create ideal tea utensils. Shitoro ware was counted among his “Seven Kilns of Enshu,” alongside Mesho ware (Shiga Prefecture), Takatori ware (Fukuoka Prefecture), Ueno ware (Fukuoka Prefecture), Akahada ware (Nara Prefecture), Kosobe ware (Osaka Prefecture), and Asahi ware (Kyoto Prefecture), earning high evaluation as tea ceramics favored by Enshu.
Enshu’s fondness for Shitoro ware stemmed from its rustic, powerful aesthetics and the subtle beauty that embodied the spirituality of tea ceremony. Particularly in tea utensils such as tea containers, tea caddies, and water vessels, Shitoro ware demonstrated a unique presence.
Development During the Edo Period
Throughout the Edo period, Shitoro ware continued to develop as a tea ceramic. Its location near Kanaya Station, which flourished as a post station on the Tokaido road, contributed to the distribution and increased recognition of Shitoro ware. Travelers and merchants spread the reputation of Shitoro ware throughout the country, and demand increased.
During this period, Shitoro ware was not limited to tea utensils; daily tableware was also produced. Many practical vessels supporting the lives of local people were created, and the industry developed as a regional pottery with strong community roots.
Changes in Modern Times and Beyond
With the modernization of society in the Meiji era, traditional pottery-producing areas underwent a major period of transition. Shitoro ware was no exception, facing a temporary crisis of decline. However, through the efforts of craftspeople committed to preserving tradition, the kiln fires were kept burning and passed down.
During the Showa period, influenced by the mingei (folk art) movement, the rustic beauty of Shitoro ware was reevaluated. While maintaining traditional techniques, craftspeople explored work suitable for modern lifestyles, and diverse pieces beyond just tea utensils—such as flower containers and tableware—were created.
Today, Shitoro ware is designated as a Shizuoka Prefecture local craft, and its techniques and spirit are being passed on to future generations through kiln owners and ceramicists committed to preserving the tradition.
Characteristics of Shitoro Ware | Materials and Techniques
Properties of the Ceramic Clay
The greatest characteristic of Shitoro ware lies in the use of locally produced ceramic clay rich in iron content. This soil uses “niishi” (ferrous stone), a local stone as its raw material, and when fired, reveals a unique tea-brown or dark brown unglazed surface.
Ceramic clay rich in iron content becomes extremely hard when fired at high temperatures. This property made Shitoro ware ideal for tea containers, and during the Edo period it was highly valued as a vessel for storing tea leaves. The durable unglazed surface could appropriately regulate moisture and preserve the quality of tea leaves over long periods.
Interestingly, some modern kiln owners use soil from the tea fields that are a specialty of Shizuoka Prefecture. This circular approach of using tea field soil to make tea utensils—an idea unique to a tea-producing region—demonstrates new possibilities for Shitoro ware.
Glazes and Color Tones
Another element characteristic of Shitoro ware is its unique glazes. Representative examples include the following:
Black Glaze (Kokuyu)
A glaze that exhibits a deep black color and is one of Shitoro ware’s representative color tones. Reduction firing of glaze containing abundant iron produces a black approaching lacquer-black in depth. This black is not merely a dark color but a black with depth that subtly shifts in expression depending on the play of light.
Amber Glaze (Ameyu)
A glaze called amber-colored tea-brown. With a warm color tone, it emphasizes rustic aesthetics. The color’s depth changes with firing conditions, and even identical glaze can create different expressions in each piece.
Shitoro Glaze
A glaze unique to Shitoro ware that exhibits deep green. Using copper as its principal ingredient, this glaze is characterized by deep green coloring. In tea utensils, this color tone harmonizes with the aesthetic of wabi-sabi and has been beloved by tea practitioners.
These glazes, combined with the iron-rich unglazed surface, create Shitoro ware’s distinctive “ancient-colored ambiance possessing both subtlety and depth.” Though unpretentious, the pieces gain deeper appreciation through use—truly embodying Japanese aesthetic sensibility.
Manufacturing Methods and Techniques
The manufacturing method of Shitoro ware is fundamentally centered on traditional handwork. Forms are created through wheel-throwing or hand-building, and after drying, pieces undergo bisque firing. Subsequently, glaze is applied and pieces undergo the final firing.
However, the process includes delicate work requiring long years of experience and technical skill. In particular, glaze mixing and the management of firing temperature and atmosphere are crucial points where the ceramicist’s technique is tested.
Firing is conducted in climbing kilns, electric kilns, gas kilns, and other types. In traditional climbing kilns, wood is used as fuel, and unique kiln effects (kiln variations) emerge from the flow of flames and temperature changes. In modern practice, electric and gas kilns that allow more stable firing are also used, though some kiln owners continue to preserve climbing kiln techniques.
Many Shitoro ware pieces are simple and undecorated. This reflects an attitude prioritizing “the beauty of the unglazed surface”—emphasizing the beauty of the material itself. The traditional Japanese ceramic aesthetic of enjoying the flow of glaze and natural changes from firing as scenery is reflected in the work.
