Otani-yaki (大谷焼) is a stoneware (炻器) produced in Otani, Oasa-cho, Naruto City, Tokushima Prefecture, with origins dating to around 1780. It was designated as a Traditional Craft by the Minister of Economy, Trade and Industry in September 2003. The tradition is particularly associated with the production of large jars used in indigo dyeing, a specialty of the Awa region, and is notable for a distinctive wheel-throwing technique requiring two practitioners working in coordination.
History
The origin of Otani-yaki dates to around 1780 (Anei 9). According to the Kuro Yakimono Yurai-ki, designated as a cultural property, the craft was founded by a potter named Bunemon from Bungo Province (present-day Oita Prefecture). Historical accounts describe how Noda Bunemon, a potter on pilgrimage to the Shikoku 88 sacred sites, arrived in Otani village with his family of five, demonstrated wheel-throwing, and prompted the village headman Mori Zeisuke to construct a bisque kiln. The initial pottery was made using red clay from Kani-ga-tani. However, research by Otaniyaki researcher Toyoda Susumu determined that the grave at Torinji in Naruto City, long venerated as Bunemon's grave, is in fact the grave of a man named Manshichi, suggesting that the true founder of Otaniyaki may be Manshichi rather than Bunemon.
Otaniyaki originally fired染付 (sometsuke) porcelain, but the domain kiln closed after only three years due to financial difficulties. In 1784 (Tenmei 4), the kiln was revived by indigo merchant Kaya Bungorō and others. With the cooperation of potters from Shigaraki in Shiga Prefecture, Otaniyaki began producing large jars to meet the growing demand associated with indigo dyeing in the Awa region. After the Meiji period, the development of synthetic dyes and changes in lifestyle caused a sharp decline in demand for these indigo jars. Despite this contraction, the craft continued, and in September 2003 Otaniyaki was designated a Traditional Craft by the Minister of Economy, Trade and Industry.
In 2015, a collaboration work between Otaniyaki and the anime Fate/stay night was produced and exhibited at AnimeJapan 2015 held at Tokyo Big Sight, selling out within one hour of opening. Also at the end of 2015, a collaboration work themed on the key visual of THE iDOLM@STER Cinderella Girls 2nd Season was produced and sold by ANIPLEX as a limited-time, made-to-order product.
Techniques & Production Process
Otaniyaki is most closely identified with its large jars (大甕), which are formed using a distinctive wheel known as the ne-rokuro (reclining wheel). This apparatus is operated by one person lying down and rotating the wheel with their feet while shaping the clay. Because of the scale and physical demands of forming large jars, the process fundamentally requires two people working in coordinated synchrony — one operating the ne-rokuro and the other shaping the vessel. This two-person throwing method is a defining characteristic of the Otaniyaki production tradition and distinguishes it from most other Japanese ceramic traditions. The early wares were made from red clay sourced from Kani-ga-tani, and the craft later incorporated the techniques of potters who came from Shigaraki, Shiga Prefecture.
How to Identify Otani-yaki
Otaniyaki is most readily identified by the scale of its characteristic large jars (大甕), which were designed to function as indigo dyeing vessels known as ai-game (indigo jars). These vessels are a practical requirement of the Awa region's indigo dyeing industry and represent the functional core of the tradition. The stoneware classification (炻器) indicates a dense, fired body distinct from earthenware or porcelain, consistent with the durability needed for use as dye vats.
The Craft Today
Otaniyaki continues to be produced in the Otani district of Oasa-cho, Naruto City, Tokushima Prefecture. The craft holds official recognition as a Traditional Craft designated by the Minister of Economy, Trade and Industry, a status it has held since September 2003. In recent years, producers have engaged with contemporary popular culture through collaboration products, including limited-edition works produced in partnership with anime franchises in 2015, demonstrating efforts to introduce the craft to new audiences. Otaniyaki and other Japanese ceramics traditions are promoted through institutions such as Aoyama Square (伝統工芸 青山スクエア), operated by the General Foundation for the Promotion of Traditional Craft Industries, located at 8-1-22 Akasaka, Minato-ku, Tokyo.
