Emperor Toba
Hōjō Masako was born in 1156, eldest child of Hōjō Tokimasa, leader of the influential Hōjō clan of Izu province, and his wife, Hōjō no Maki. Masako's parents were still in their teens, so she was raised by many ladies-in-waiting and nannies. Masako was born into a world of war and strife. In Kyoto, the capital of Japan, the Hōgen Rebellion was in full swing. Cloistered Emperor Toba and Emperor Sutoku warred over who would be the next emperor. The Hōjō clan wisely chose to stay out of the rebellion, even though the Hōjō family was descended from the Taira clan and thus was related to the imperial family.
