Karatsu-yaki

Karatsu-yaki (唐津焼) is a ceramic tradition produced in the eastern part of present-day Saga Prefecture and the northern part of Nagasaki Prefecture since the 1580s. Karatsu ware covers a wide range of vessel types, from everyday utensils to tea utensils, with diverse styles and techniques. Together with its branch Takeo-Ko-Karatsu ware, it is designated as a Traditional Craft of Japan. For broader context on Japanese ceramic traditions, see Japanese Ceramics: The Complete Guide.

History

Based on kiln site investigations and ceramic shard finds at consumption sites such as Sakai, the start of Karatsu ware production is believed to have begun in the 1580s, slightly before the Bunroku-Keichō campaigns. The name "Karatsu ware" is said to derive from the fact that products were shipped from the port of Karatsu, though this etymology is not certain. Early kilns developed under the patronage of Hata Chikashi and are scattered at the foot of Kishidake mountain, in areas corresponding to the former Kitahata Village and Ōchi Town of present-day Karatsu City. The Kishidake Ko-Karatsu kiln group is divided into two lineages: the Handōgame-gama system and the Hobashira-gama system, the latter producing Madara-Karatsu using straw ash glaze.

Sen no Rikyū, who died in Tenshō 19 (1591), is known to have owned an Oku-Kōrai tea bowl of Karatsu ware called "Nenoko-mochi." The oldest surviving Karatsu ware piece with an inscription is a black-glazed four-eared jar bearing a Tenshō 20 (1592) inscription, held at Shōmo-gū shrine in Iki City, Nagasaki Prefecture. The earliest written record of Karatsu ware appears in the Keichō 8 (1603) tea ceremony records of Furuta Oribe, which mention a "Karatsu ash-glazed water jar" and a "Karatsu striped water jar." By the time of the haiku treatise Kefukigusa by Matsue Shigeyori, completed in Kan'ei 15 (1638), Karatsu had become a general term for earthenware, distinguished from Imari porcelain.

After the Bunroku-Keichō campaigns, Hizen pottery production areas expanded and came to be classified by kiln location: Matsuura-type, Takeo-type, and Hirado-type Ko-Karatsu. The Nabeshima domain subsequently consolidated kilns, concentrating production in Arita, which caused considerable disruption to Karatsu. However, kilns continued to operate as official kilns (goyō-gama) producing tea ceramics. Following the Meiji Restoration, Karatsu ware declined rapidly due to the loss of domain patronage, and many kilns were closed. The later Living National Treasure Nakazato Muan revived traditional Ko-Karatsu techniques such as tataki-zukuri (paddle construction) and successfully re-established the craft. The 2005 municipal merger consolidated the area containing early Ko-Karatsu kiln sites in the former Kitahata Village and former Ōchi Town into present-day Karatsu City.

Techniques & Production Process

Karatsu ware employs techniques said to have originated in Yi Dynasty Korea, or possibly southern China, including the kick-wheel (keri-rokuro) and paddle construction (tataki-zukuri). The kilns used were Korean-style split-bamboo shaped climbing kilns (warichiku-gata nobori-gama). Ware is fired in a large connected-chamber climbing kiln (renbo-shiki nobori-gama) at a high temperature of 1,300 degrees in a single firing.

Several distinct decorative styles define the tradition. E-Karatsu is made by drawing designs of flowers, birds, and plants on vessels using an iron solution called "oni-ita," then applying a transparent glaze such as gray glaze before firing. Chōsen-Karatsu (Korean Karatsu) involves applying iron glaze from the top for black coloring and straw ash glaze from the bottom for white, with the two glazes intersecting to create landscape-like patterns; the Fujinokawachi Kayanotani kiln site in Matsura Town, Imari City is known for producing much Chōsen-Karatsu ware. Madara-Karatsu is produced by mixing feldspar with straw ash and firing, causing the iron content in the clay to form blue or black spots. Kobiki (powder-drawing) Karatsu uses brownish clay over which white slip (keshotsuchi) is applied to the entire surface while still half-dry, followed by glaze after drying. Ao-Karatsu (blue Karatsu) is made by applying wood ash glaze and firing, which produces blue-celadon-like coloring through heating, with pieces from the Handōgame upper and lower kiln sites considered representative examples.

Mishima-Karatsu inherits the technique of Korean Mishima-de ceramics and involves impressing designs such as cloud-crane or flower patterns on half-dried vessels, applying white slip, finishing, then applying feldspar or charcoal glaze before firing. Nishiki-Karatsu (two-color Karatsu) uses iron glaze, which fires to brown, and copper glaze, which fires to green, to draw patterns such as pine, landscape, and arabesque designs; this style was widely used from the latter half of the 17th century.

How to Identify Karatsu-yaki

Tea bowls from Karatsu are historically ranked by the saying "first Raku, second Hagi, third Karatsu" (一楽二萩三唐津), reflecting their longstanding status among tea ceremony wares. Each of the major styles carries distinct visual markers: E-Karatsu is identifiable by iron-painted designs of flowers, birds, and plants under transparent glaze; Chōsen-Karatsu by its two-tone glazing where black iron glaze and white straw ash glaze intersect; Madara-Karatsu by irregular blue or black spotting caused by iron content in the clay reacting with straw ash and feldspar glaze; Kobiki Karatsu by a visible white slip layer over brownish clay; Ao-Karatsu by a blue-celadon coloring from wood ash glaze; Mishima-Karatsu by impressed decorative motifs filled with white slip; and Nishiki-Karatsu by the combination of brown and green patterned glazes. Karatsu ware in general spans both rustic stoneware sensibilities and refined tea wares.

The Craft Today

Currently there are approximately 50 kiln workshops (kamamoto) operating in Karatsu. Ancient kiln sites are distributed across a wide area including Karatsu City, Takeo City, Imari City, and Arita Town in Saga Prefecture, as well as Sasebo City and Hirado City in Nagasaki Prefecture, reflecting the historical breadth of the tradition. The Handōgame-shita kiln site, where part of the kiln floor and walls remain, is designated a Saga Prefecture historic site. Karatsu ware, together with its branch Takeo-Ko-Karatsu ware, continues to hold official designation as a Traditional Craft of Japan. Visitors to Tokyo can view designated traditional crafts, including Karatsu ware, at Dentou Kogei Aoyama Square (8-1-22 Akasaka, Minato-ku, Tokyo), which is open from 11:00 to 19:00 year-round except for year-end and New Year holidays, and is operated by the General Foundation for the Promotion of Traditional Craft Industries.
