The Complete Guide to Hagi Ware: A Thorough Explanation of Yamaguchi Prefecture’s Traditional Ceramics, History, and Characteristics
Hagi ware, boasting a history of over 400 years centered in Hagi City, Yamaguchi Prefecture, is one of Japan’s representative traditional ceramics. With its simple and warm aesthetic and its unique characteristic of “Hagi’s Seven Transformations” (hagi no nana-bake), where the flavor increases with use, it has been beloved by tea practitioners and many others. This article comprehensively introduces the charm of Hagi ware, from its history and the characteristics of its production region to its techniques and purchasing methods.
What is Hagi Ware: Basic Knowledge of Yamaguchi Prefecture’s Representative Ceramics
Hagi ware (hagiyaki) is pottery produced primarily in Hagi City, Yamaguchi Prefecture. It is said to have begun when ceramic artisans Li Shaoguang (Ri Shakkō) and Li Jing (Ri Kei), brothers invited from the Korean Peninsula, opened a kiln in 1604 (Keichō 9).
Definition and Characteristics of Hagi Ware
Hagi ware is defined as ceramics with the following characteristics:
- Raw Materials: Uses ceramic clay such as daidō clay (daidōtsuchi) and Mishima clay (mishimatsuchi) quarried near Hagi
- Firing Temperature: Fired at relatively low temperatures of approximately 1200–1250 degrees Celsius
- Texture: Possesses a soft, water-absorbent earthen quality
- Color: Features gentle hues such as pale white, light yellow, and pale red
- Glaze: Primarily uses natural glazes such as rice-straw ash glaze (warabaiyū) and wood ash glaze
The greatest characteristic of Hagi ware lies in its water absorbency. Because the soil particles are coarse and fine cracks (crackle or kan’nyū) appear in the base, as the ware is used, tea or sake gradually seeps through, changing the color of the vessel. This phenomenon is called “Hagi’s Seven Transformations” and is a major attraction of Hagi ware.
The Hagi Ware Production Region: History and Geography of Hagi City, Yamaguchi Prefecture
Geographic Characteristics of Hagi City
Hagi City is a castle town in the northern part of Yamaguchi Prefecture, facing the Sea of Japan. During the Edo period, it prospered as the base of the Chōshū Domain (Mōri clan), and today retains much of the atmosphere of a castle town. The Hagi production region as a source of Hagi ware had the following geographic advantages:
- Abundant High-Quality Ceramic Clay: The Hagi vicinity was rich in clay suitable for pottery production, such as daidō clay and Mishima clay
- Abundant Fuel: Firewood necessary for pottery firing could be stably supplied from the surrounding mountains
- Convenient Maritime Transport: Facing the Sea of Japan, it was advantageous for shipping products and procuring raw materials
- Domain Protection: As an official kiln of the Mōri Domain, it received generous protection from the domain
Distribution of Major Kilns
Many kilns are still scattered throughout Hagi City, with the principal production areas as follows:
- Matsumoto District: Said to be the birthplace of Hagi ware, with the oldest kiln remains
- Tsubakihigashi District: An area where many kilns are concentrated
- Mikami District: Traditional kilns scattered throughout
- Central Hagi City: Many galleries and sales shops for tourists
Hagi City has approximately 100 kilns, where ceramics are created while preserving tradition yet incorporating contemporary sensibility.
A 400-Year History of Hagi Ware: From Korean Ceramic Artisans to the Present Day
The Edo Period: Birth and Development of Hagi Ware (1604–1868)
The history of Hagi ware began in 1604 (Keichō 9). During the Toyotomi Hideyoshi’s campaigns in Korea (Bunroku and Keichō Wars), Mōri Terumoto invited Korean ceramic artisans Li Shaoguang and Li Jing to open a kiln in Matsumoto, Hagi. This is considered the origin.
Li Shaoguang took the Japanese name Sakakōraizaemon (坂高麗左衛門), and Li Jing took the name Sakakura Shinbei (坂倉新兵衛), each opening a kiln. The Sakakōraizaemon family in particular continued the name “Kōraizaemon” through successive generations and became a prestigious kiln that continues to the present day.
During the Edo period, Hagi ware developed primarily for the following uses:
- Tea Ceramics: Became highly prized as tea utensils such as tea bowls and tea containers as tea ceremony flourished
- Official Domain Kiln: As an official kiln of the Mōri Domain, produced luxury items for domain lords and the samurai class
- Everyday Wares: Also produced daily dishes for common people
Hagi ware as tea ceramics, in particular, was loved by tea practitioners as, according to the saying “first Raku, second Hagi, third Arita,” a superior tea bowl following Raku ware.
The Meiji Period Onward: Modernization and Preservation of Tradition (1868–Present)
Following the Meiji Restoration, Hagi ware, having lost the domain’s patronage, faced a temporary crisis of decline. However, from the late Meiji period through the Taishō period, it was reassessed under the influence of the folk art movement.
Development in the Showa Period:
- 1957 (Showa 32): Miwa Kyūsetsu (10th generation) designated as a Holder of Important Intangible Cultural Property (Living National Treasure)
- 1983 (Showa 58): Hagi ware designated as Traditional Craftsmanship by the Minister of International Trade and Industry (now Minister of Economy, Trade and Industry)
- 2003 (Heisei 15): Miwa Kyūsetsu (12th generation) designated as a Holder of Important Intangible Cultural Property
Contemporary Hagi Ware:
In the contemporary era, while preserving traditional techniques, younger artists create vessels with contemporary design. Beyond tea utensils, a wide range of works are created, including daily-use tableware, flower containers, and objects.
Hagi Ware Manufacturing Techniques and Characteristics
Clay and Glaze Used
Types of Ceramic Clay:
- Daidō Clay (daidōtsuchi): Quarried in the Daio district of Hagi, it is white-toned clay. Low in iron content, it has a whitish finish after firing
- Mishima Clay (mishimatsuchi): Quarried on Mishima Island off the coast of Hagi, it is reddish-brown clay. High in iron content, it has a reddish tint after firing
- Mitake Clay (mitaketsuchi): Clay quarried near Mount Mitake within Yamaguchi Prefecture
These clays are used singly or in combination. Hagi ware clay has coarse particles and is rich in plasticity, making it suitable for wheel throwing.
Types of Glaze:
- Rice-Straw Ash Glaze (warabaiyū): Glaze with straw ash as its main ingredient. Produces a pale milky-white finish
- Wood Ash Glaze (mokubaiyū): Glaze made from mixed-wood ash. Has a slightly yellowish tone
- Soil Ash Glaze (dobaiyū): Glaze made from a mixture of soil and ash
- White Glaze (shiroyū): A transparent white glaze
Hagi ware glazes are centered on ash glazes from natural materials rather than chemical glazes. This results in natural and warm colors.
Forming Techniques
Hagi ware forming employs primarily the following techniques:
- Wheel Throwing (rokuro seikei): The most common technique. The clay is drawn upward on a rotating wheel to form the shape
- Hand Pinching (tebineri): Forming the clay while pinching it by hand. Allows more individual shapes
- Slab Forming (tatara seikei): Clay stretched into a sheet is formed against a mold
- Carving (sakuri dashi): After wheel throwing, the piece is carved when still leather-hard to refine the shape
In particular, Hagi ware tea bowls are roughly formed on the wheel and then refined by carving the foot (kōdai), with overall balance adjusted. This carving technique is an important element expressing the artist’s individuality.
Firing Method
Types of Kiln:
Traditionally, climbing kilns (noborrigama) have been used, but in the contemporary era the following kilns are employed:
- Climbing Kiln (noborrigama): A traditional kiln built on a slope. Uses firewood as fuel and produces distinctive firing colors
- Pit Kiln (anagama): A kiln created by digging into the ground. Primitive but produces powerful fired results
- Gas Kiln: Allows easy temperature control and stable firing
- Electric Kiln: Offers the easiest temperature control and is usable even by small-scale kilns
Firing Temperature and Time:
Hagi ware is fired at relatively low temperatures of approximately 1200–1250 degrees Celsius. This temperature is lower than porcelain (1300 degrees or higher), and as the soil particles do not become completely vitrified, a soft, water-absorbent texture is created.
Firing time varies depending on the kiln type and work size, but in climbing kilns, it typically takes 2–3 days of slow firing.
“Hagi’s Seven Transformations”: The Charm of Change with Use
The greatest characteristic of Hagi ware, “Hagi’s Seven Transformations” (hagi no nana-bake), is explained in detail.
The Mechanism of the Seven Transformations
Because Hagi ware is fired at relatively low temperatures, fine gaps remain between soil particles. Additionally, due to the different shrinkage rates of glaze and base, fine cracks called “crackle” (kan’nyū) appear on the surface.
Through these cracks and soil gaps, liquids such as tea or sake gradually seep in during use. As a result:
- Color Change: The originally whitish vessel gradually changes to brown, beige, or sometimes greenish tones
- Appearance of Patterns: Tea stains seep along the cracks, creating unique patterns
- Change in Texture: With use, the surface becomes smoother and develops a sheen
These changes are called “scenery” (keshiki) and display different appearances depending on the user. Even vessels fired in the same kiln show completely different transformations depending on how they are used and what beverage is consumed in them.
How to Enjoy the Seven Transformations
Points for maximizing enjoyment of the seven transformations:
- Pre-Use Preparation: Before use, new Hagi ware can be soaked overnight in rice-rinsing water or water to prevent dirt from seeping in
- Regular Use: Frequent use creates uniform and beautiful transformations
- Post-Use Care: It is important to wash immediately after use and allow it to dry thoroughly
- Storage Method: Store in a location with low humidity to prevent mold growth
In the case of tea bowls, drinking the same type of tea daily creates beautiful scenery over 5–10 years. This “joy of cultivation” is a major attraction of Hagi ware.
Types and Uses of Hagi Ware
Tea Utensils
As Hagi ware developed as tea ceramics, tea utensils are its most representative products:
- Tea Bowl (chawan): A representative masterpiece of Hagi ware. Called a superior work as “first Raku, second Hagi, third Arita”
