Let us here describe the feudal government organized by Yoritomo at Kamakura--the first attempt of like kind in the history of Japan--and observe how different it was from the elaborate system of the centralized government which was first organized in 645 and later transferred to Kyōto. One of the first steps taken by the Minamoto chief to consolidate his power was to establish the relation of lord and vassal between himself and the great local magnates of the eastern provinces who had espoused his cause, and to secure their allegiance by confirming them in the possession of their estates. For the better organization of his military forces he created an office called _samurai-dokoro_, a species of headquarter staff department, which was presided over by Wada Yoshimori in the capacity of _bettō_. Thus all the military men throughout the east were brought completely under his sway. Later he created a department of public archives (_kumonjo_), and made Ōye Hiromoto its minister, and Nakahara Chikayoshi its vice-minister, both of whom were originally civilians at Kyōto. It was owing to Yoritomo's sagacity that they had been induced to enter the service of the military government at Kamakura. By this department the administration of civil affairs was chiefly conducted, as was the administration of military affairs by the staff department (_samurai-dokoro_). A department of justice (_monchū-jo_) was also organized with Miyoshi Yasunobu, another civilian, at its head, its functions being the hearing of all civil suits, and the management of matters relating to civil law.
