The so-called "Momoyama Period" is generally believed to have begun in 1563 and ended in 1615. Through the efforts of several generations of military generals such as Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, the separatist situation of political power was finally ended during this period and the country was unified. The arrival of a new political era has created favorable conditions for the development of culture and art. On the one hand, although the war against Korea launched by Toyotomi Hideyoshi ended with the defeat of the Japanese army, during the seven-year war, a large number of Korean craftsmen were kidnapped and brought to Japan, among which it is said that there were as many as 800 potters alone. . At that time, the Lee Dynasty of Korea was at the peak of porcelain production and design. The introduction of Korean ceramic craftsmanship experience undoubtedly laid the foundation for the maturity of Japanese ceramic craftsmanship.
