The power of the He family was thus completely broken, and that of the Gen or Minnamoto firmly established, mainly through the prowess and generalship of Yoshitzune. Yoritomo began to be jealous of his brother on account of the credit and reputation he had gained by his success. He picked a quarrel with him on the ground of his having married a daughter of the enemy of the house, Kio mori, and sent forces against him, demanding of the Emperor that his father-in-law, Hojio, should be appointed generalissimo, by this means filling the places of command with his own creatures. Yoshitzune left the capital and retired to Oshiu to his old friend Hide Hira, governor of the province. Yoritomo was enraged at an asylum being given to his brother in the north, and sent orders to have him put to death. Yasu hira, the son of his old friend, attacked him, and Yoshitzune, being unprepared and seeing no way of escape, destroyed himself, after first killing his wife and children. Yoritomo, angry with the man for doing what he himself had ordered, marched against Yasu hira with a large army, and finally destroyed him. Yoritomo built a palace for himself in Miako, but appears generally to have lived at Kamakura. At this latter place are to be seen to this day the remains of his work in the roads cut through rocks which confined the space of ground set apart for his residence. In 1190 he went to Miako, where he had built a palace, and in great state visited the Emperor; but after a month’s residence in the capital he returned to Kamakura. In 1192 the old Emperor Go zira kawa died at the age of sixty-seven. He had lived, after his abdication, during parts of the reigns of five emperors, his sons and grandsons. He had during forty years taken a very active part in the working of the government, and had passed through the most exciting time in the history of his country. His last years were spent in tranquillity. Yoritomo was appointed Sei dai Shiogoon. Suspecting his brother Nori Yori of plotting against him, he banished him to Idzu, where he was soon after put to death. He again visited the capital for four months in 1195, but returned to Kamakura, from which place he virtually ruled the empire. He fell from his horse toward the end of 1198, and died shortly after, in 1199, at the age of fifty-three. He is generally regarded as the greatest hero in Japanese history. But his treatment of his brother has been a great blot upon his character, and lowered him very much in the regard of his countrymen. Yoshitzune is looked upon as the mirror of chivalry, and his conduct is held up to the youth of the country for imitation, rather than the calculating, bloody, though brilliant career of Yoritomo.
