Taishu ware is porcelain from the Tsushima Tachikame region (currently Izuharamachi of Tsushima City in Nagasaki Prefecture), and has been in production since at least before the Kaei era (1848-54), but the period it officially began and when it was abandoned are unknown. From the works that still exist, most is porcelain known as blue and white porcelain or white porcelain with a blue and white inscription of ‘Junsei Tachikame in a double circle’. The kilns are seen as drawing upon the style of Imari. Also, it is said that there were potters known as Juntaro and Uhe, but little of their work still exists and there are many things that are unknown.
Tsushu ware is also called Tsushima ware, which sometimes includes the work of the Busan kilns in Korea, so in this case it refers to the Korean style pottery.
