The Joseontonsinsa in the late Joseon period brought a letter of state from the King of Joseon to the Tokugawa Shogun, along with an annex containing a list of courtesies to the Shogun, his successor, and Ogosyo (Retired Shogun), including ramie cloth, ginseng, tiger skin, hawks, and horses. Of these, the hawk and horse were considered symbols of authority, and it is thought that they became courtesies in combination with the Shogun's preferences. Therefore, it can be assumed that the negotiation of the hawk and horse by the Tsushima domain is a matter related to the Shogun's authority, and must be considered as a matter related to the prestige of the Tsushima domain, whose family role is diplomatic service between Japan and the Joseon. In addition, it is significant to clarify the transportation system of the Tsushima domain, the support system for the transportation by the feudal lords by sea and land, and the cooperation between the Tsushima domain and the feudal lords to clarify the whole picture of the transportation of the hawks and horses. From this perspective, previous studies have only partially clarified the details, such as the verification of the transportation by sea in “Ushimado Town History” and the analysis of the personnel composition related to transporting hawks by land by Hiroshi Nakao. This article focuses on Tsushima’s negotiations regarding hawks and horses, as well as the movements of the Tsushima domain and its officials in transporting hawks from Busan to Edo, centering on the Joseontonsinsa of 1711. As a result, it was revealed that the negotiation between hawks and horses was made upon the request of Tsushima Domain based on precedent and shogunate’s intention. It was also confirmed that the support system for the transportation was prepared based on the information provided by the Tsushima domain, and that the hawks and horses traveled along the same route as the Joseontonsinsa both by sea and land. In addition, the sea route and the land route traveled the same route as the carrier of the Joseontonsinsa, who was in charge of the transfer. Moreover, it was also revealed that the hawks transferred to Edo were selected by the shogunate officials as gifts to the shogunate. This trend, where the Tsushima Domain and its officers supported the shogunate authority, significantly contributed to the stability of the Japanese-Joseon relationship.
