Introduction of pottery Zen priests are linked with two very characteristic elements of Japanese culture: the exquisite simplicity of Japanese ceramics; and the polite formalities of the Tea Ceremony for which much of the pottery is designed. In 1223 a Zen monk takes a Japanese potter, Kato Shirozaemon, to China to study the manufacture of ceramics. This is a period, in the Song dynasty, when the Chinese potters have achieved a perfection of simplicity. The Japanese, in the same vein, will evolve their own styles to rival this perfection. The Japanese potter, returning home, establishes himself at Seto. This rapidly becomes a center for the manufacture of pottery, with as many as 200 kilns in the dtrict.

This becomes much in demand with the increasing popularity in the samurai class of the Tea Ceremony, in which a mood of rustic simplicity is required.

This porcelain with polychrome painting was appearing in various styles, such as ko-imari, with its sumptuous brocade style.

With their decorative styles, both artists and their pupils influenced the development of ceramics far beyond the bounds of Kyoto. Many potters from provinces were sent by their feudal loads or by rich merchants to be trained in Kyoto, or the Kyoto masters were invited to the provinces
