Answer:
Minamoto Yoritomo was a Japanese military leader and the founder of the shogunate, which for the next 700 years was mostly the center of power in Japan. The shogun was given the right to appoint regional administrators, the shugo, military governors for the provinces, and the jito, who arranged military taxes for the estates. Their position came alongside that of the existing civil bureaucracy, but became more powerful over time. Indirectly this also made the shogun more powerful, although this decreased again later, because the shugo and jito were able to take an increasingly independent position.
