Sen Dōan

Sen no Dōan (千道安) (1546–1607) was a Japanese tea ceremony master. He was the eldest son, hence the blood descendant and natural heir, of Sen no Rikyū, born between Rikyū and Rikyū's first wife, known as Hōshin Myōju. His brother-in-law was Sen Shōan, and one of the reasons for the complexity of the family lineage after Rikyū is that Shōan, rather than Dōan, became the Sen family successor.
