Sen Sōtan

Sen Sōtan (千宗旦^?) (1578–1658), also known as Genpaku Sōtan 元伯宗旦, was the grandson of the famed figure in Japanese cultural history, Sen Rikyū. He is remembered as Rikyū's third-generation successor in Kyoto through whose efforts and by whose very being, as the blood-descendant of Rikyū, the ideals and style of Japanese tea ceremony proposed by Rikyū were able to be passed forward by the family. He was the son of Sen Shōan and Okame, a daughter of Rikyū, and is counted as the third generation in the three lines of the Sen family known together as the san-Senke (see Schools of Japanese tea ceremony). He helped to popularize tea in Japan. It was in the generation of his children, Sōsa, Sōshitsu and Sōshu, that the three lines of the family—the Omotesenke, Urasenke and Mushakōjisenke—were established, with these three sons, respectively, as their heads of house. They are counted as the fourth generation in the respective lines.

At around the age of ten, he was sent to live at Daitoku-ji temple, through the wish of his grandfather, Rikyū. He lived at the sub-temple Sangen'in, under the supervision of the priest Shun'oku Sōen. During the years following Rikyū's death, when the Sen family was disbanded and Sōtan's father found shelter with the daimyō Gamō Ujisato in distant Aizu Wakamatsu, Sōtan was able to stay safely at Daitoku-ji temple. When his father was at last permitted to return to Kyoto and reestablish the Kyoto Sen family, Sōtan left the priesthood and returned to his family. His father soon left the headship of the family to Sōtan, and moved out.
