Oichi

Oichi (お市^?, 1547–1583) was a female historical figure in the late Sengoku period. She is known primarily as the mother of three daughters who married well – Yodo-dono,Ohatsu and Oeyo.

Oichi was the younger sister of Oda Nobunaga; and she was the sister-in-law of Nōhime, the daughter of Saitō Dōsan. Oichi was equally renowned for her beauty and her resolve. She was descended from the Taira and Fujiwara clans.

Following Nobunaga's conquest of Mino in 1567, in an effort to cement an alliance between Nobunaga and rival warlord Azai Nagamasa, Nobunaga arranged for Oichi, then twenty years old, to marry Nagamasa. Their marriage was through political means, ensuring an alliance between the Oda and the Azai clans. She bore Nagamasa one son (Manjumaru) and three daughters – Yodo-dono, Ohatsu and Oeyo.

In the summer of 1570, Nagamasa betrayed his alliance with Nobunaga and went to war with him on behalf of the Asakura family. A story relates that Oichi sent her brother a sack of beans tied at both ends, ostensibly as a good-luck charm but in reality a warning that he was about to be attacked from both front and rear by the Asakura and Azai clans. According to the story, Nobunaga understood the message and retreated from his brother-in-law's assault in time.

The fighting continued for three years until the Asakura and other anti-Oda forces were destroyed or weakened. Oichi remained with her husband at Odani Castle throughout the conflict, even after Toyotomi Hideyoshi, a trusted vassal of Nobunaga at the time, began laying siege to the castle. When Odani was surrounded, Nobunaga requested that his sister be returned to him before the final attack. Nagamasa agreed, sending out Oichi and her three daughters. Nagamasa had no hope of winning, and chose to commit seppuku.
