Born in 1178 as the eldest daughter of Yoritomo and Masako. Around 1182, as part of a political accommodation between her father and Kiso Yoshinaka, Yoshinaka's young son Yoshitaka was sent to Kamakura as a hostage and treated as Ohime's betrothed. The two children grew up together in Kamakura with genuine fondness. But when Yoshinaka was killed at Awazu in 1184, Yoritomo ordered Yoshitaka's execution to remove a political threat. Ohime was only 6 years old. The loss of Yoshitaka wounded her deeply, and she never truly recovered. As she grew older, she reportedly lost her appetite and spent her days in grief. Her father Yoritomo repeatedly plotted to marry her into the Imperial family to extend his influence, but Ohime refused every such scheme. She died of illness in 1197 at age 20. Masako reportedly mourned her deeply. Ohime's tragedy has endured as a story embodying the cold cruelty of Kamakura-era political power.

Sensitive and pure-hearted. Her love for young Yoshitaka never faded, and she refused all political marriages. The depth of her grief moved all who knew her.

A symbol of tragic love in the Kamakura period. Her childhood romance, sacrificed to politics, has been depicted in numerous literary works, illustrating the cruelty of warrior society.
