Feudal Japan: What is the difference between an emperor and a shogun, and who had more power?

What is the difference between an emperor and a shogun, and who had more power? Well, emperors have reigned over Japan for more than 1,500 years, and that they have all descended from the same imperial family, and are thought to be very powerful. A Japanese shogun is a person of military rank and historical title for in most cases hereditary military dictator of Japan. It may look like an emperor has more power but in fact a shogun has more power. The emperor was just a de jure figurehead ruling position. The shogun defiantly had more power than the emperor.
