Consort of Toyotomi Hideyoshi; mother of Toyotomi Hideyori
"I will not leave this castle. It was my uncle’s, and it will be mine to the end."
Chacha was Oda Nobunaga's niece, the eldest daughter of his sister Oichi and the doomed general Azai Nagamasa, whom Nobunaga had destroyed in battle when she was a small child. She survived Nagamasa's death and, years later, the destruction of her stepfather Shibata Katsuie at Shizugatake in 1583 — where Oichi committed suicide with her husband as their castle burned, and Chacha and her sisters were taken in by the very man, Hideyoshi, who had just defeated their family. She became Hideyoshi's favoured consort and, in 1593, the mother of his only surviving heir, Hideyori — a birth so improbable, given Hideyoshi's age and lack of other children, that rumours of the child's true paternity circulated even at the time, though nothing was ever proven and Hideyoshi treated Hideyori as his own without reservation. After Hideyoshi's death she governed Osaka Castle in her young son's name, styled Yodo-dono, and became the effective political head of the remaining Toyotomi cause against Tokugawa Ieyasu. She refused every opportunity to negotiate her son's survival on Tokugawa terms and pushed for the resistance that produced both Osaka campaigns. When the castle finally fell in June 1615, she and Hideyori committed suicide together inside it as the fortress burned — closing a life that had begun watching Nobunaga destroy her father's clan and ended watching Nobunaga's former ally destroy her son's.

Her father was destroyed by Nobunaga, her stepfather by Hideyoshi at Shizugatake, and her son by Tokugawa Ieyasu at Osaka — three of the unification’s central figures, each responsible for the death of a different man in her life.
November 1614 – January 1615 · 20,000 total casualties
A siege decided by engineering fraud rather than battle. The negotiated truce specified filling in the outer moat; Tokugawa work crews filled in the inner moats as well while Toyotomi negotiators were occupied elsewhere, stripping the castle of the defences that had made the winter assaults so costly. It left Osaka Castle essentially indefensible for the campaign that followed within months.
June 3, 1615 · 100,000 total casualties
The end of the Toyotomi line and, with it, the last serious military resistance to Tokugawa authority. It closes the unification cycle exactly where it began — with the destruction of an entire clan and the killing of its heirs, the method Nobunaga and Hideyoshi had themselves used on the Azai, the Takeda, and the Hōjō, now turned by Ieyasu on Hideyoshi's own son. What followed was two hundred and fifty years without a major civil war, purchased by finishing the Sengoku period's logic all the way to its end.
