Imari ware (伊万里焼 Imari-yaki?) is a type of Arita ware (有田焼 Arita-yaki?) traditionally made in the town of Arita, in the former Hizen Province, northwestern Kyūshū. They were exported to Europe extensively from the port of Imari, Saga, between the second half of the 17th century and the first half of the 18th century. The name therefore derives from the port of export. Imari ware has been continuously produced up through the present day.
"Imari" was simply the trans-shipment port for Arita wares. It was the kilns at Arita which formed the heart of the Japanese porcelain industry.
Arita's kilns were set up in the 17th century, when kaolin was discovered in 1616. A popular legend attributes the discovery to an immigrant Korean potter, Yi Sam-pyeong (1579–1655), although most historians consider it doubtful. After the discovery some kilns began to produce revised Korean-style blue and white porcelains, known as "Shoki-Imari".
In the mid-17th century there were also a lot of Chinese refugees in Northern Kyushu due to the turmoil on Chinese continent, and it is said one of them brought coloring technique to Arita. Thus Shoki-Imari developed into Ko-Kutani Imari. Ko-Kutani was produced around 1650 for both export and domestic market. Kutani ware is characterized by vivid green, blue, purple, yellow and red colors in bold designs of landscapes and nature. Blue and white porcelain pieces continued to be produced and they are called Ai-Kutani. Ko-Kutani Imari for the export market usually adopted Chinese design structure such as kraak style, whereas Ai-Kutani for the domestic market were highly unique in design and are accordingly valued very much among collectors.
