or (1569 – June 4, 1615) was a prominently placed figure in the late-Sengoku period. She was the daughter of Oichi and sister of Ohatsu and Oeyo. She was a concubine and second wife of Toyotomi Hideyoshi, who was then the most powerful man in Japan. She also became the mother of his son and successor, Hideyori. Her time period being that of large turmoil and overhaul, Yodo-dono had an interest toward both politics and administration. She actively acted in the restoration of the Toyotomi clan after the fall of the Council of Five Elders, as Hideyori's guardian. Alongside her son, Yodo-dono led the last anti-Tokugawa shogunate resistance in the siege of Osaka. When her two younger sisters became prominent members linked to the Tokugawa clan, Oichi's three daughters were vital to maintaining a diplomatic relationship between the two most powerful clans of the time, Toyotomi and Tokugawa. Her sister, Oeyo, was the wife of the second shogun, Tokugawa Hidetada, and matriarch of the successive shoguns' lineage, thus receiving the political title Omidaidokoro. The relationship of Tokugawa and Toyotomi has been falling steadily since Hideyoshi's death, so it led both clans to the Battle of Sekigahara and later to the siege of Osaka. Due to the attempt to exalt the Tokugawa Shogunate, Yodo-dono was frequently portrayed as a "wicked and wanton" woman who planned the Toyotomis' death. She was also known as Lady Chacha (茶々). After the death of Hideyoshi, she took the tonsure, becoming a Buddhist nun and taking the name Daikōin (大広院). She was the founder of the temple Yogen-in (養源院). The great wealth and changing fortunes of her family affected Yodo-dono's life as well. Surviving record books from luxury goods merchants provide insight into patterns of patronage and taste amongst the privileged class of women like Yodo-dono and her sisters. Genealogy Yodo-dono, also called in her youth, was the eldest of three daughters of the Sengoku period daimyō Azai Nagamasa. Her mother, Oichi was the younger sister of Oda Nobunaga. After Nagamasa's death, Toyotomi Hideyoshi became the adoptive father and protector of Chacha. Her status changed once when she became his concubine, and once again when she became the mother of his heir. Lady Okurakyo no tsubone (Ono Harunaga's mother), Lady Aeba no tsubone (the second daughter of her grandaunt, Kaitsu-dono), and Otsubone (a wife of Sawaki Yoshiyuki and brother of Maeda Toshiie) were Chacha's wet nurses
