Yodo-dono or Yodogimi (1569 - 1615) was a prominently-placed figure in the late-Sengoku period. 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. She was also known as Lady Chacha. In 1594; the family moved to Fushimi Castle; but tragedy befell them when Hideyoshi died in 1598 and the Toyotomi clan lost much of its influence and importance. Yodo-dono moved to Osaka Castle with her son Hideyori and plotted the restoration of the Toyotomi clan. Tokugawa Ieyasu; who seized control from Hideyori after the death of his father; now viewed Hideyori as an obstacle to his unification of Japan. He laid siege to Osaka Castle in 1614; but the attack fell through; and subsequently he signed a truce with Hideyori. However; in 1615; Ieyasu broke the truce and once again attacked Osaka Castle; and this time he succeeded. Yodo-dono and her son Hideyori committed suicide; thus ending the Toyotomi legacy.
