Research on Josentongsinsa have been developed significantly over time in many various fields such as literature, painting, clothing, architecture, medicine, geography, etc. Moreover, area studies have been actively conducted on the transit areas of Japan where Josentongsinsa had stayed. However, there have been only a small number of research on the major transit areas, especially on Iki. Thus, in this research, the exchange activities in Iki were readdressed based on the records of Sahaengrok(diplomatic missions) written by Josentongsinsa, and some data from Japan. The features of the exchange activities in terms of the history and industries of Iki were especially scrutinized since they were not examined much in other previous literature reviews. Iki was in a close relationship with Korea, receiving advanced cultural resources due to its location on the sea route connecting to the Korean Peninsula and the Japanese archipelago. Even though there were times when Iki was in a hostile position regarding the invasion of the Wakou(Japanese dwarf pirates) and Toyotomi Hideyoshi to Joseon, it can be assumed that Iki made its best effort to build and maintain an amicable relationship with its neighbor through the exchange activities with Josentongsinsa in the late Joseon dynasty. In Iki, whaling had been prevalent since B.C. and in the late Josen dynasty, it emerged as one of the most developed and leading industries in that area. It is found that the people of Iki used the whaling with their utmost efforts as hospitality for Josentongsinsa. The fact that the people of Iki demonstrated the whaling process and showed their own authentic local culture was also noticed. Furthermore, the whale meat which was their local specialty was included in the dishes served for Josentongsinsa and Josentongsinsa expressed their interest in the different food cultures. These facts indicate that the characteristics of the sea route of Iki played one of the factors that affected the exchange activities with Josentongsinsa. Some interactions and exchanges with local people of Iki can be also presumed as it was the transit area in the sea route where the itinerary can be unexpectedly changed due to the weather change. Unfortunately, there have been only a few related remains in Iki causing the slow progress of the relevant studies in the present, unlike other transit areas. It is hoped that future research on the exchange activities in Iki especially based on analysis of the old records such as historical data that are not cited yet could be further elicited.
