This article deals with the institution of the retired emperor from the mid-17th century on and its organizational characteristics. The author first focuses on the rotation of aristocrats attending the emperor at his retirement palace at Sakuramachi-Dono, examining the cases of Emperor Go-Mizuno and Reigen, tracing the division and integration of the duties involved and finally the formation of a system for communications, household administration and staffing. The most significant development in this process occurred in 1687 upon the retirement of Emperor Reigen, when the duties of the post of imperial secretary (giso 議奏), who up until that time had served both the enthroned and retired emperors, was divided into a giso serving the former and an indenso 院伝奏 for the latter. The author then examines Ret. Empress Meisho from the standpoint of staff salaries, concluding that the fact that the Empress was kin to the Tokugawa Shogunate led to her denso having special privileges, which were incorporated into the system organized under Reigen and thus applied to all denso from that time on. Next, the incorporation of organization aspects of Reigen's household into the emperor's palace operations is discussed in order to clarify the presence of assistants to the denso, called yoninshu 四人衆 in the Reigen household, posts that were not made a permanent part of the retired emperor's operations thereafter and whose duties remained undefined. The author concludes that although the retired emperor's household administration system did incorporate some of the aspects of the Gomizuno and Meisho retirements, the Reigen household was organized independently of the reigning emperor. While the retired emperor exerted a great deal of influence in late premodern Japanease court, with the revival of enthronement of a successor before the previous emperors death, the way in which the retired emperor's household was managed did not resemble the "Insei" 院政 institutions set up during the late eleventh century.
