Nagamasa Azai
served: Oda

Oichi was known primarily as the mother of three daughters who married well -- Yodo, Ohashi and Oeyo. She was married to Katsuie Shibata and Nagamasa Azai.


Still young Oichi married the Oda retainer Katsuie Shibata.

Following Nobunaga's conquest of Mino in 1567, in an effort to cement an alliance between Nobunaga and Nagamasa Azai, 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 named Manjumaru and three daughters who were Yodo, 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 Hideyoshi Toyotomi, 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 was killed by Nobunaga. When she returned to the Oda she again became the wife of Katsuie Shibata.

After Nobunaga's deathEdit

Oichi and her daughters remained in the Oda family's care for the next decade. After Nobunaga was assassinated in 1582, his sons and vassals broke into two major factions, led by two of Nobunaga's favored generals, Katsuie and Hideyoshi. Nobunaga's third son, Nobutaka, belonged to the former group, and arranged for his aunt Oichi to marry Katsuie in order to ensure his loyalty to the Oda clan. But in 1583, Katsuie was defeated by Hideyoshi in the Battle of Shizugatake, forcing him to retreat to his home at Kitanosho Castle. As Hideyoshi's army lay siege to the castle.


Katsuie implored Oichi to flee with her daughters and seek Hideyoshi's protection. Oichi refused, insisting on dying with her husband after their daughters were sent away. The couple reportedly died in the castle's flames.
