Goryeo is the former name of Korea. In Japan, Koryo is still used as a nickname for Joseon, and the conquest of Korea by Toyotomi Hideyoshi (1592-8) during the Bunroku and Keicho periods was called “the entry of the Koryo Dynasty”. All of the Koryo tea bowls prized in the tea ceremony came from Korea in the past, but none of them date back to the Koryo period. The classification of Koryo tea bowls among tea masters is as follows. Wells, brush washers, wari-takadai, kotoya koryo, kureki, hanshi, painted koryo, iraho, yellow koryo, persimmon koryo, hakeme, koryo celadon, mishima, kohiki (powder-fired), ameboshi, tamago hand, soft hand, hard hand, kinhai, kumagawa, goshomaru, koryo fukiboku, gohon, fish shop, kakinokaki, white koryo, untsuru, and others. Furthermore, there are various names that further subdivide this category. Not all of the items used in these tea bowls are original tea bowls, but many of them were made to look like tea bowls, such as brush washers, incense burners, kataguchi, vinegars, pickle containers, and ritual vessels.
