In this study, article, the author investigates the meaning that commands issued by the Ashikaga Shoguns had for the daimyo during the Warring States period from two perspectives: the relationship between them out of "utilization and restriction", and the mutual relationship of confrontation among daimyo focusing primarily on those of Western Japan as well as the nature of the effect that trends in such commands had on the behavior. In other words, (1) even during this period, daimyo required a stable relationship with the Shogun due to various circumstances such as the need to obtain legitimacy and to keep hostile forces in check and there was a tendency for them to take advantage of the shogun. (2) While they took advantage of this relationship with the Shogun, however, daimyo were also subjected to various restrictions such as the need to honor the commands of the Shogun (or, the need to honor the wishes of third parties through such commands). This made the commands of the Shogun an important tool in diplomatic relations with daimyo as confrontations between them broadened in scale and increased in complexity during the period. (3) In addition, Daimyo in the Kinki area (Kinai) gained the ability to control these commands by cooperating in the existence of the Shogun and, thereby, promoted collaboration with various other daimyo through the commands, which had become an important tool in the diplomatic relations between daimyo or secured opportunities for them to exercise influence over other daimyo. Various factors such as (1)? (3) above acted to further draw many more daimyo to the side of the Shogun, even after the advent of the Warring States, becoming a factor in the maintenance of a certain degree of influence by the Shogun over the daimyo. This influence of the Shogun on the Daimyo was extremely useful for the daimyo in their diplomatic strategies and was an authority unique to the Shogun on a dimension completely different from the control of the daimyo over their territories. It was therefore not easy for the daimyo to acquire such authority. However, by backing the Shogun, Oda Nobunaga succeeded in gaining the influence 'that the Shogun had over the daimyo and, while gradually exercising that influence, he moved ahead with the task of unifying the nation.
