She married Nagamasa Asai, Lord of Omi (Shiga Prefecture). Gave birth to three daughters.
After Nobunaga destroyed the Asais, Otani married Katsuie Shibata, Lord of Echizen (Fukui Prefecture), taking her three daughters with her.
Upon Hideyoshi's forces besieging Katsuie at Kitanosho (1583), she made her three daughters escape to Ichijo-ga-tani, exchanged cups of wine with her husband and the couple, singing together, set their castle on fire and killed themselves. Her third daughter was Yodogimi, the famous mistress of Hideyoshi.
