Minamoto no Yoritomo Minamoto no Yoritomo was the founder and the first shogun of the Kamakura shogunate and of Japan, ruling from 1192 until 1199, also the first ruling shogun in the history of Japan. He was the husband of Hōjō Masako who acted as regent (shikken) after his death. Yoritomo was the son of Minamoto no Yoshitomo and belonged to Seiwa Genji's prestigious Kawachi Genji family. After successfully maneuvering himself to the position of rightful heir of the Minamoto clan, he led his clan against the Taira from his capital in Kamakura, beginning the Genpei War in 1180. After five years of civil war, the Minamoto clan finally defeated the Taira in the Battle of Dan-no-ura in 1185. Yoritomo established the supremacy of the samurai caste and the first shogunate (bakufu) which was to be centered around Kamakura, thus beginning the feudal age in Japan, which lasted until the 17th century.
