Imari-yaki is a general term for porcelain from the Arita region of Saga Prefecture. Imari-yaki does not include the well known Kakiemon and Nabeshima kilns, which are archrivals. Imari porcelain was first potted at Arita Sarayama in the 1610s. In Japanese, Sarayama refers to "the original," or "ancient site" where porcelains or potteries were made. The name Imari comes from the nearby port from which this porcelain was shipped to China, Europe and other areas of Japan. Porcelain was a relatively unknown commodity in seventeenth-century France.
The word, Ko-Imari, means old Imari in Japanese although some collectors of Japan prefer to name Kinrande also called Nishikide porcelain as Ko-Imari style to distinguish from the Nabeshima and the Kakiemon. In its general sense, Ko Imari should cover all the Imari porcelain products which were produced in the Hizen province before the Meiji-era in Japan.
Susudake is bamboo that is taken from old straw-thatched house ceilings where it has changed to an auburn color by absorbing the smoke of the 'irori' hearth ... The rich color of this bamboo, called susudake—"soot bamboo"— darkened by years of exposure to the smoke of the hearth, is highly valued and expensive, and sometimes 2-300 years old.
