As the northernmost traditional kiln in Japan, it is called the “Northern Limit Folk Kiln,” and its warm vessels made from local clay and simple glazes were highly praised by Soetsu Yanagi of the Folk Craft Movement. This article provides a detailed explanation of Kokujiyaki’s history, current efforts, and its appeal.
What is Kokujiyaki | Basic Information on the Northern Limit Folk Kiln
Kokujiyaki (こくじやき) is a ceramic fired in Kokuji Town, Kuji City in the northeastern part of Iwate Prefecture. As the northernmost traditional kiln in Japan, it bears the alternate name “Northern Limit Folk Kiln” and is known as a ceramic ware deeply rooted in the region’s culture and daily life.
Geographic Location and Land Characteristics
Kuji City is located in the northeastern part of Iwate Prefecture, facing the Pacific Ocean, and high-quality clay is abundantly available in the coastal areas. The clay mined in this region becomes the basic material for Kokujiyaki, and together with glaze made from local iron sand and rice husk ash, it becomes an important element in creating a distinctive appearance.
Characteristics of Kokujiyaki
The greatest characteristic of Kokujiyaki lies in its simplicity and practicality. The slightly thick vessels are suited for everyday use, and the distinctive astringency and warmth created by glazes utilizing local materials are appealing. Warm white glaze made from straw ash and candy glaze made from iron sand are representative glazes, both of which have been inherited as glazes unique to Kokujiyaki.
History of Kokujiyaki | From the Edo Period to Present
Origins of the Business (1813)
The history of Kokujiyaki began in the 10th year of the Bunka era (1813). It is said to have originated when the first generation, Kumagai Jinemon, invited a ceramicist named Kashizo from Soma, Fukushima Prefecture, to learn ceramic techniques. According to another account, the ceramicist Kashizo from Soma, with the help of Rokuro Amatanal from Kokuji, built a kiln in Mikakucho, and multiple oral traditions remain.
The first generation, Kumagai Jinemon, studied under ceramicist Kashizo who came from Soma and acquired his techniques. Regarding glaze, he created glazes unique to Kokujiyaki based on locally available clay, and this technique has been handed down to the present day.
Relationship with the Hachinohe Domain
In its early days, Kokujiyaki functioned as the official kiln of the Hachinohe Domain. Flower bowls, plates, and jars were fired and used as official commemorative items of the domain. This relationship with the Hachinohe Domain greatly contributed to the improvement of Kokujiyaki’s quality and techniques, becoming an important factor in establishing its position as a kiln.
Development as Everyday Tableware for Common People
While serving as the official kiln of the Hachinohe Domain, Kokujiyaki also devoted efforts to firing everyday tableware for common people. Using clay abundantly available along the coastal areas, it manufactured tableware and household items used in local homes, becoming deeply rooted in the region’s culture and lifestyle.
Encounter with the Folk Craft Movement
In the 20th century, Kokujiyaki attracted the attention of Soetsu Yanagi, founder of the Folk Craft Movement. In particular, the simple one-spouted vessel with its elongated mouth was highly evaluated for its simplicity and beauty, and recognized as a vessel embodying the ideals of folk crafts. Through this evaluation, Kokujiyaki became known nationwide.
Modernization and Maintenance of Tradition
As times changed and lifestyles transformed, the environment surrounding ceramics also changed dramatically. There was once a period when the number of kilns decreased, but through continuous efforts to preserve tradition, the techniques and spirit of Kokujiyaki are still inherited today.
Manufacturing Technique of Kokujiyaki | Traditional Hand-Making Process
Commitment to Local Clay
The manufacturing of Kokujiyaki begins with using clay from Kuji. The clay mined locally serves as the foundation for creating Kokujiyaki’s distinctive appearance and has been used unchanged since 200 years ago. Understanding the characteristics of this clay and handling it appropriately is the first step in producing high-quality vessels.
Forming with the Potter’s Wheel
Kokujiyaki still inherits old techniques and uses the potter’s wheel to finish each vessel by hand. Even in modern times when mechanization has progressed, commitment to hand-wheel forming by craftsmen creates subtle adjustments in thickness and individuality in shape. By finishing with a slightly thicker form, practicality for everyday use and heat retention are realized.
Glaze Mixing and Glaze Application
Kokujiyaki’s glaze is made from iron sand and rice husk ash. White glaze made from straw ash produces a warm color, while candy glaze made from iron sand creates distinctive astringency. These glazes are unique to Kokujiyaki, and traditional mixing methods utilizing local materials are preserved.
Firing Technique
In the firing process, temperature control and time distribution are important. Kokujiyaki kilns optimize the glaze color development and vessel strength through firing techniques based on long years of experience. Through this process, the simple yet beautiful vessels of Kokujiyaki are completed.

Charm of Kokujiyaki | Why It Continues to Be Loved
Commitment to Local Materials
The greatest appeal of Kokujiyaki is its continued commitment to local clay mined in Kuji and glaze made from iron sand and rice husk ash. By utilizing materials unique to this region, a distinctive appearance that cannot be imitated elsewhere is created.
Reconciliation of Practicality and Beauty
Kokujiyaki is made with practicality as the first priority, yet its simple beauty aligns with the ideals of folk crafts. The thickness and form designed for ease of everyday use, and the simple design that enhances dishes, are vessels that grow more endearing with use.
Warmth of Handwork

Inheritance of History and Culture

How to Use and Care for Kokujiyaki
Tips for Everyday Use
Kokujiyaki is made with everyday use in mind, so no special handling is required. However, soaking the piece in water once before initial use prevents dirt from sticking. Regarding microwave and dishwasher use, it varies by product, so confirmation at time of purchase is recommended.
Care for Long-Term Use
Washing promptly after use and thorough drying are important. Ceramic absorbs moisture easily, so storage in humid locations should be avoided. Regular sun-drying prevents mold growth and maintains the piece in good condition for years to come.
Enjoying Aging and Weathering
Kokujiyaki gains depth with continued use. Glaze expression may change, or crazing (fine cracks on the surface) may appear, but this is characteristic aging and weathering of ceramics. As a vessel that grows with daily life, these changes can be enjoyed.
