Minamoto no Yoritomo, born on May 9, 1147, was a prominent samurai and the first shogun of the Kamakura shogunate, a pivotal figure in Japanese history. He emerged as a leader of the Minamoto clan, successfully claiming his position as the rightful heir and leading his forces against the Taira clan, igniting the Genpei War in 1180.
After five years of intense conflict, Yoritomo's strategic prowess culminated in the decisive victory at the Battle of Dan-no-ura in 1185, which established the Minamoto clan's dominance. This victory not only marked the end of the civil war but also heralded the beginning of the feudal age in Japan, with Yoritomo at the helm of the newly formed shogunate.
As the first shogun to wield de-facto power over Japan, Yoritomo's reign from 1192 until his death in 1199 laid the foundation for the samurai caste's supremacy. His marriage to Hōjō Masako, who would later serve as regent after his passing, further solidified his legacy. Notably, early texts such as the Mutsu Waki describe Yoritomo as an incarnation of Bishamonten, the god of the north, highlighting his revered status.
