Minamoto no Yoritomo was a samurai, daimyo and the founder and the first shogun of the Kamakura shogunate, ruling from 1192 until 1199, also the first shogun in the history of Japan to hold de-facto power over Japan. He was married to Hōjō Masako, who acted as regent (shikken) after his death. The early 11th-century text Mutsu Waki 陸奥話記 says Yoritomo is an incarnation of the god of the north Bishamonten.
