Born in 1138, a local strongman of Izu Province. His life changed when his daughter Masako married Minamoto no Yoritomo, and he fully backed Yoritomo's uprising of 1180. In the early Kamakura Shogunate he held both the mandokoro and samuraidokoro simultaneously. After Yoritomo's death he emerged as the de facto supreme power, orchestrating the destruction of the Hiki clan in 1203 and becoming the first regent. But swayed by his second wife Lady Maki's ambitions, he had the powerful Hatakeyama Shigetada killed in 1205. When he further attempted to replace Shogun Sanetomo with his son-in-law (the Maki Incident), his own son Yoshitoki and daughter Masako acted first and exiled him to Izu. He died at 77. He is the founder of Hojo regent rule.

An ambitious and wily politician. He gained Yoritomo's trust and embedded himself in the shogunate's core, but in his later years his judgment was compromised by his second wife, leading to his downfall.

Founder of Hojo regency rule. He simultaneously held the offices of mandokoro-betto and samuraidokoro-betto in the shogunate's early days, establishing the Hojo power base.
