Tsurugaoka Hachiman-gū
Yoriyoshi accompanied his father Minamoto no Yorinobu on his own missions to defend the Empire, quelling rebellions and disturbances. Thus he gained much of his knowledge of tactics and strategy. He fought in the Zenkunen War for twelve years starting in 1051, including the Battle of Kawasaki. In 1063, Yoriyoshi founded Tsurugaoka Hachiman-gū in Kamakura which was to become, roughly a century later, the primary shrine of the Minamoto clan when they began the Kamakura shogunate.
