- Hōjō Tokimasa
▪ Japanese warrior and regentborn 1138, Izu Province, Japandied Feb. 6, 1215, IzuJapanese warrior who aided Minamoto Yoritomo in establishing the Kamakura shogunate, the military government by which Yoritomo ruled the country from his base at Kamakura in central Japan, while the emperor continued to rule only symbolically from his residence at Kyōto, to the southwest. After Yoritomo's death, Tokimasa transferred the power of government from Yoritomo's descendants to his own family.Tokimasa's original family name was Taira, but early in his life he changed it to Hōjō, the name of his domain in eastern Japan. In 1160, when the great warrior Taira Kiyomori (1118–81) killed Minamoto Yoshitomo (1123–60) and thereby established his domination over all Japan, Yoshitomo's young son Minamoto Yoritomo was sent under the watchful care of Tokimasa to Izu in eastern Japan.Tokimasa became attached to the boy to whom he gave his own daughter, Masako, in marriage, and in 1181 he assisted him when he rose in revolt against Kiyomori. After Yoritomo's victory, Tokimasa helped Yoritomo establish the shogunate, wielding great power as the shogun's father-in-law.Upon Yoritomo's death (1199), Tokimasa became the head of a council of leading warriors and politicians of the state in a move to check the power of Yoritomo's tempestuous son and successor, Yoriie. In 1204 Tokimasa finally had Yoriie murdered, and the shogunate passed to Yoriie's younger brother, Sanetomo. As Sanetomo was still a minor, Tokimasa was appointed to the newly created post of shikken, or regent, to the shogun.Meanwhile, Tokimasa's second wife urged her husband to depose Sanetomo and place her son-in-law on the throne as the new shogun. In 1205 an attempt was made on the Shogun's life, but he was saved by his mother, Tokimasa's daughter Masako.Masako and her brother Hōjō Yoshitoki then called a council meeting and forced their father to resign. Yoshitoki replaced him as regent, the office thus becoming the property of the Hōjō family. After his replacement, Tokimasa entered the priesthood and lived out the rest of his life in retirement.
