Onishi Toki
Sake Ware with Golden Patterns Born from Triple Firing
While most pottery undergoes two firings—biscuit firing followed by main firing—this unique piece with golden kiln effects is created through a rare third firing. The clay, rich in iron content and sourced from Ōtani, undergoes a special firing process during the third stage that triggers a chemical reaction, naturally revealing golden patterns on the surface. Because these patterns emerge through natural transformation, no two pieces are ever the same.
Ōnishi Tōki: A Kiln with Over a Century of Heritage
Ōnishi Tōki was founded in 1919 by Yonekichi Ōnishi, who began producing both large-scale ceramics and tableware. The pottery, made from locally sourced red clay high in iron content, is characterized by a rough texture and a faint luster. The climbing kiln once used for firing large ceramic vessels was said to be one of the largest in Japan, attracting potters from across the country who came to witness its scale and techniques.
The current head of the kiln, Naoki Ōnishi, represents the sixth generation of the family and was officially recognized in 2024 as a nationally designated Traditional Craftsperson. Moving beyond the traditional color palette of Ōtani ware—typically black and brown—he has developed new glazes in bright blue and Japan Blue (a deep indigo), ushering in a new era for Ōtani ware with contemporary expressions.
Ōtani Ware: A 240-Year Tradition from Tokushima
Ōtani ware is a traditional craft with a history spanning over 240 years, representing the rich cultural heritage of Tokushima Prefecture. It is produced in the Ōtani area of Naruto City, known for its iron-rich clay deposits. Originating in the late Edo period, Ōtani ware flourished with the production of large ceramic vessels such as aigame (indigo jars) and mizugame (water jars), which were essential tools in Tokushima’s thriving indigo industry.
A hallmark of Ōtani ware is the unique "ne-rokuro" technique, in which one craftsman lies horizontally to spin the wheel with his feet, while another shapes the clay—an ingenious method developed specifically for making large-scale ceramics.
