Tokoname-yaki

Tokoname-yaki (常滑焼) is stoneware produced in and around Tokoname City, Aichi Prefecture, on the Chita Peninsula. It is one of Japan's Six Ancient Kilns (Nihon Rokkoyō), a group that also includes Seto-yaki, Echizen-yaki, Tamba-tachikui-yaki, Bizen ware, and Shigaraki-yaki. On April 29, 2017, Tokoname-yaki was designated as a Japan Heritage site as part of the Six Ancient Kilns designation.

History

Tokoname-yaki originated in the first half of the 12th century (late Heian period) through the southward migration of ash-glazed pottery kilns from the southern Sanage kiln area. Medieval kiln sites in the region number over 1,000 and possibly several thousand, with one scholarly estimate reaching as high as 10,000. Products from the late Heian period have been found at Buddhist sites such as sutra mounds (kyōzuka) and in large quantities at the Ōshū Hiraizumi ruins. Excavations at the Kusado Sengen-chō ruins in Fukuyama City, Hiroshima, also yielded many Tokoname wares from the Kamakura period.

During the Muromachi period, kiln structures transitioned from underground anagama to semi-above-ground ōgama (large kilns), also known as teppō-gama. There is a theory that Oda Nobunaga issued a kiln prohibition order (kin'yō-rei) in Tenshō 2 to protect Seto pottery production, which may have temporarily affected Tokoname production; however, in 1983, Akabane Ichirō argued in his book Tokoname that this order did not affect Tokoname production.

During the Edo period, the term "Tokoname ware" referred collectively to ceramics fired in three villages: Tokoname village, Segi village, and Hōjō village. A Genroku-era kiln inspection recorded two kilns each in Tokoname and Segi villages and eight in Hōjō village; Hōjō village subsequently had ten kilns in the Kyōhō era, eight in the Tenmei era, and eleven in the Tenpō era. Edo-period output was divided into two categories: mayake (high-temperature vitrified ware) and akamono (lightly fired red ware).

During the Bunsei era, Inaba Takamichi (Shōzaemon) obtained an ancient manuscript at Enshū Akiha-san and produced the first kyūsu (teapot) in Tokoname based on its contents. In Ansei 1, Sugie Jumondō (Yasuhei), guided by physician and kyūsu collector Hirano Tadashi, succeeded in creating shudei (red clay) similar to the material used in Chinese teapots. The renbōshiki noborigama (climbing kiln) was introduced to Tokoname during the Tenpō era by Koie Kosaburō (Hōkyū) of Segi village, with assistance from his son Isaburō (Hōju).

In Meiji 11, Koie Hōju invited Jin Shikō, a Chinese literati knowledgeable about Yixing kiln tea ware techniques, to instruct Tokoname potters. Modern ceramic pipe (dokan) production began in Meiji 5 with an order from Richard Brunton for sewage works at a newly reclaimed site in Yokohama. Architectural ceramic (tile) production began around the end of the Meiji era; scratch tiles and terracotta for Frank Lloyd Wright's Imperial Hotel were produced in Tokoname, contributing to rapid growth in architectural ceramic output. The Great Kantō Earthquake struck on September 1, Taishō 12, during the celebration of the Imperial Hotel's opening. The Tokoname Pottery Industry Cooperative, formed in Meiji 33, succeeded in testing a downdraft coal kiln in Meiji 34, leading to the rapid spread of coal kilns; from around the time of the revised Air Pollution Control Act in Shōwa 45, these coal kilns switched to heavy oil fuel.

Shudei ryūmaki (red clay dragon-coil ware) was test-produced in the Meiji 10s and fully exported from the Meiji 20s and 30s, primarily to the North American market. A drainage facility discovered at the outer moat of Kōriyama Castle in Yamato Kōriyama City, estimated to have been built in the early 17th century, is thought to incorporate Tokoname ware pipe and was found to have been in use for approximately 170 years; this was reported in 2020. In 2001, a Tokoname ware exhibition sold ceramics decorated with Arimatsu-Narumi shibori patterns, attracting wider attention. A historical precedent for combining stoneware with shibori patterns exists in "Narumi Oribe" from the early Edo period.

Techniques & Production Process

Medieval Tokoname kilns were underground anagama kilns (chika-shiki anagama) dug into the hillside slopes of the Chita Peninsula. During the Muromachi period, kiln construction transitioned to semi-above-ground ōgama, also called teppō-gama. The climbing kiln (renbōshiki noborigama) was subsequently introduced during the Tenpō era.

A distinctive technique associated with Tokoname is the mogake (fire-color firing) method, developed by the second-generation Ina Chōsan, who discovered a white clay called itayama-tsuchi and wrapped dried seaweed around the clay body before firing to produce characteristic surface patterns. Shudei (red clay) teapots became a defining product category following Sugie Jumondō's successful development of red clay material in Ansei 1. Shudei ryūmaki export wares were decorated with thin relief dragon motifs formed using plaster molds and attached to the surface; finished pieces were sent to Kobe for additional lacquer and gold leaf processing. Knowledge of Yixing kiln techniques was introduced directly from China when Jin Shikō was invited to Tokoname in Meiji 11 to teach local potters. Architectural ceramics, including tiles and terracotta, also became a significant part of Tokoname's production repertoire from the late Meiji era onward.

How to Identify Tokoname-yaki

Tokoname-yaki encompasses a range of forms, most notably kyūsu (teapots) made from shudei (red clay), which distinguishes them from lighter-bodied or glazed wares. Pieces produced using the mogake technique display surface markings caused by seaweed wrapped around the clay prior to firing, resulting in characteristic fire-color patterns on a white clay body. Export-period shudei ryūmaki pieces feature applied dragon reliefs in thin clay, often with subsequent lacquer and gold leaf decoration applied in Kobe. The ware category also includes high-temperature vitrified pieces (mayake) and lightly fired red wares (akamono), reflecting the broad range of firing conditions historically employed at Tokoname kilns.

The Craft Today

Tokoname-yaki continues to be produced in and around Tokoname City on the Chita Peninsula in Aichi Prefecture. The craft's designation as part of the Japan Heritage Six Ancient Kilns group in 2017 has provided institutional recognition for its historical significance within Japanese ceramics. In 2001, the introduction of Arimatsu-Narumi shibori-decorated Tokoname ware at exhibition attracted attention, indicating continued interest in combining the tradition with other regional craft techniques. The General Incorporated Foundation for the Promotion of Traditional Craft Industries (一般財団法人伝統的工芸品産業振興協会) operates Densan Aoyama Square, a venue in Tokyo's Minato-ku that presents and promotes Tokoname-yaki alongside other designated traditional crafts.

Frequently Asked Questions

What are Japan's Six Ancient Kilns, and is Tokoname-yaki one of them?

Japan's Six Ancient Kilns (Nihon Rokkoyō) are Tokoname ware, Seto ware, Echizen ware, Tamba-Tachikui ware, Bizen ware, and Shigaraki ware. Tokoname-yaki is counted among them and was designated as a Japan Heritage site as part of this group on April 29, 2017.

When did Tokoname-yaki originate?

Tokoname-yaki originated in the first half of the 12th century (late Heian period), developing from the southward migration of ash-glazed pottery kilns in the southern Sanage kiln area.

What is shudei, and why is it significant to Tokoname-yaki?

Shudei is a red clay material similar to that used in Chinese Yixing teapots. In Ansei 1, Tokoname potter Sugie Jumondō (Yasuhei) succeeded in developing shudei, guided by physician and kyūsu collector Hirano Tadashi. This material became central to Tokoname's identity as a teapot-producing region.

What is the mogake technique?

The mogake technique involves wrapping dried seaweed around clay before firing. It was developed by the second-generation Ina Chōsan, who also discovered a white clay called itayama-tsuchi. The seaweed creates characteristic fire-color surface patterns on the finished piece.

What types of products has Tokoname produced beyond teapots?

In addition to teapots and tablewares, Tokoname has produced ceramic pipes (dokan) for civil engineering purposes since Meiji 5, when an order from Richard Brunton initiated their production for Yokohama sewage works. Architectural ceramics including tiles and terracotta were also manufactured from the end of the Meiji era, and scratch tiles and terracotta for Frank Lloyd Wright's Imperial Hotel were notably produced in Tokoname.
