Mikawachi-yaki

Mikawachi-yaki (三川内焼) is a ceramic ware produced in the Mikawachi area of Sasebo City, Nagasaki Prefecture, with origins traceable to 1598, and designated as a Traditional Craft Product by the Minister of Economy, Trade and Industry in 1978 (certification number 14-119). Also known as Hirado-yaki, it is classified among the Hizen ceramics of northern Kyushu and is recognized for its white porcelain body decorated with blue-painted designs.

History

The origins of Mikawachi-yaki are connected to the Korean campaigns launched by Toyotomi Hideyoshi, after which the feudal lord of the Hirado domain, Matsura Shigenobu, brought back Korean potters to his territory. In 1598, a potter named Koseki (also referred to as Kyoseki) naturalized and took the surname Imamura. By order of the domain lord, he fired the first kiln at Nakano-gama in Nakano village on Hirado Island; this Nakano-yaki kiln is regarded as the origin of Mikawachi-yaki.

Around 1622, depletion of clay in Nakano village prompted Koseki and his son Imamura Sannojo to search for new clay sources within the domain. That same year, a Korean potter named Kōraibō moved to the Mikawachi area after marrying into the Nakazato Mozaemon household. In 1637, Koseki finally settled in Mikawachi, and in 1650 the Hirado domain relocated potters from Nakano village to Mikawachi, consolidating production there.

During the early modern period, the ware — known under its alternative name Hirado-yaki — was frequently presented as gifts to the shogunal family, the imperial court, and court nobles. Danish art historian and museum director Emil Hannover (1864–1923) praised Hirado-yaki in his writings, asserting that pieces produced between 1750 and 1830 represented the finest porcelain in Japan, surpassing even Hasami-yaki and other regional traditions in milky whiteness and luster.

A distinctive tradition of eggshell-ware (Rankaku-de) was developed by Ikeda Anjiro and others of Ainouura (Ainoura) origin, in response to a domain order to produce a tea bowl lighter than chopsticks. This ware became popular in Europe under the name "eggshell." Production ceased after World War II but was restored in 2006 by the Hirado Tosho-gama kiln; after restoration, eggshell-ware was presented to the Imperial Household and given to other notable persons. To mark the 400th anniversary of Mikawachi-yaki, a large dish featuring 400 Tang children (Karakoe) figures was produced and can be viewed at the Mikawachi-yaki Museum.

Techniques & Production Process

Mikawachi-yaki uses Ajiro pottery stone from Hario Island and Amakusa pottery stone from Higo to produce its characteristic white porcelain body. Eggshell-ware, however, must exclusively use Ajiro pottery stone from Hario Island, and must be hand-formed and fired using the okoshi-yaki (raised firing) method.

A key decorative technique associated with Mikawachi-yaki is Okiage, a form of relief work perfected in Mikawachi around 1680 during the mid-Edo period. The technique involves placing clay bit by bit on a brush tip to build up relief patterns on the surface. Unlike Okiage work from other regions — where the applied relief often cracks or peels — the raised portion in Mikawachi pieces is integrated with the body. This technique is recognized as a precursor to pâte-sur-pâte, regarded as one of the highest techniques in Western porcelain. Among the wider landscape of Japanese Ceramics, the Okiage method represents a notable contribution from the Hizen tradition to global ceramic practice.

How to Identify Mikawachi-yaki

Mikawachi-yaki is characterized by blue-colored painted decoration applied to a white porcelain body. A signature motif is the Karakoe (Tang children) design, depicting children holding Tang fans and playing under a pine tree, with butterflies flying over peonies. The number of Tang children in a design historically indicated the intended recipient: seven children denoted a presentation piece for the shogunal family or imperial court; five children was the standard for court nobles and daimyo families; and three children was intended for the general public. Pieces from the period 1750 to 1830 are noted in historical criticism for their milky whiteness and luster. Eggshell-ware is distinguished by its extreme thinness, made possible by the exclusive use of Ajiro pottery stone and the okoshi-yaki firing method.

The Craft Today

As of current records, there are 14 kilns (kamamoto) producing Mikawachi-yaki in the Mikawachi area of Sasebo City, Nagasaki Prefecture. The craft continues to be recognized under its 1978 METI designation. Mikawachi-yaki shares the broader Hizen ceramic heritage of Nagasaki with Hasami-yaki, another porcelain tradition from the same prefecture. Regional white porcelain traditions comparable in character include Izushi-yaki from Hyogo and Tobe-yaki from Ehime. The eggshell-ware tradition, revived in 2006, represents an active effort to maintain one of the craft's most technically demanding product lines.

Frequently Asked Questions

What is Mikawachi-yaki?

Mikawachi-yaki is a porcelain ceramic ware produced in the Mikawachi area of Sasebo City, Nagasaki Prefecture. It is also known as Hirado-yaki and is classified among the Hizen ceramics. It was designated a Traditional Craft Product by the Minister of Economy, Trade and Industry in 1978.

What is the Karakoe (Tang children) motif?

The Karakoe motif depicts Tang children holding Tang fans, playing under a pine tree with butterflies flying over peonies. The number of children depicted — seven, five, or three — historically indicated whether a piece was made for the shogunal family and imperial court, for court nobles and daimyo, or for the general public respectively.

What is eggshell-ware (Rankaku-de) in Mikawachi-yaki?

Eggshell-ware is an exceptionally thin type of porcelain developed at Mikawachi in response to a domain order to create a tea bowl lighter than chopsticks. It must use only Ajiro pottery stone from Hario Island and be hand-formed using the okoshi-yaki firing method. Production ceased after World War II but was restored in 2006 by the Hirado Tosho-gama kiln.

What is the Okiage technique?

Okiage is a relief-decoration technique perfected in Mikawachi around 1680. It involves placing small amounts of clay on a brush tip to build up raised patterns on the porcelain surface. The Mikawachi method integrates the relief with the body of the piece, unlike versions from other regions where the applied relief may crack or peel. The technique is recognized as a historical antecedent to the Western pâte-sur-pâte method.
