Chaa no Tsubone

Lady Chaa was a Japanese noble woman and concubine of Tokugawa Ieyasu, the founder of the Tokugawa shogunate in Japan. She lived in Tōtōmi Province. She is said to be the daughter of a foundryman. When the daikan had her husband killed, she appealed to Ieyasu, who was then the lord of Hamamatsu Castle; as a result, he punished the daikan. Lady Chaa subsequently became a concubine of Ieyasu. She was also the mother of Matsudaira Tadateru and Matsudaira Matsuchiyo. An account cited that Lady Chaa was part of Osaka Castle's Genji circle and received a copy of Genji monogatari no okori from her aunt, Keifukuin Kaoku Gyokuei.
