Although the Japanese invasions of the Korean peninsula in 1592-1598 are sometimes known as the Pottery Wars or Teabowl Wars and are acknowledged as a turning point in the history of Japanese ceramics, they have not yet been the subject of an exhaustive study that draws on both Korean and Japanese sources. This article attempts to synthesize the data available in scattered Japanese sources in order to give an overview of present knowledge concerning the total scope of relocation of Korean potters to Japan in the aftermath of the Teabowl Wars. The transfer of Korean potters by the western Japanese warriors participating in the Teabowl Wars represents the climax of a longstanding Japanese awareness of advanced Korean technologies, including ceramics. Korean teabowls are listed in the earliest extant records of the tea ceremony (1530s). It seems probable that small numbers of Korean potters were already active in northern Kyushu and in Kyoto before the Teabowl Wars. The mass arrival of Korean potters in Japan in the 1590s, however, made possible the establishment of new ceramic workshops within numerous fiefs throughout western Japan. The Korean craftsmen introduced advanced kiln technology that provided the basis for widespread production of glazed and decorated ceramics. Potters from remote areas of Korea not previously connected to Japan through trade brought hitherto- unknown ceramic types. Through the efforts of Korean potters, porcelain was manufactured for the first time in Japan. Not all new ceramic workshops succeeded, however, and the failures resulted in large part from changes in clan economies arising from shifts in political power. At the same time, as the products of the new kilns assimilated the rapid changes in taste and style within the tea ceremony, sixteenth-century Korean shapes were quickly replaced by distinctly Japanese forms. By the mid-seventeenth century, Kyoto was established as the trend-setting center of ceramic production, and the provincial kilns founded by Korean potters followed the lead of the capital. In retrospect it becomes clear that the major effect of the Teabowl Wars was to introduce a large body of trained ceramic craftsmen to Japan; the skills of those craftsmen were directed toward stylistic innovation rather than toward replication of the once-coveted Korean tea wares.
