This doctoral thesis presents a historical study of the diplomatic exchanges between the Japanese and the Korean embassy in the eighteenth century. Neighbourly relationships (J: kōrin, K: kyorin) were maintained between Tokugawa Japan (1603-1868) and Chosŏn Korea (1392-1910) for more than 250 years. The visitations of the Korean embassy, dispatched to congratulate a new Tokugawa shogun, were often seen as the symbol of their amicable and friendly relationship, and it is well known that the Koreans were cordially welcomed by the Tokugawa bakufu. Despite these neighbourly relations, the visitations of the embassy had a more pragmatic purpose. More complex political conditions and nature were immanent within and between the both states. In the diplomatic interaction, the officials in the two states had traditional and obstinately-held perceptions towards the counterpart hidden behind the pleasant gesture. In this thesis, I attempt to uncover what is associated with these neighbourly relations, by revealing the cultural awareness and consciousness of these two states in East Asia through detailed examinations of the historical sources. To find the notions behind the exchange, my thesis illustrates Japanese and Korean hua-yi awareness that came to light through the interactions between the Japanese and the Koreans. The Chinese hua-yi order, the concept of looking at the Chinese dynasties as the center, was said to dominate the East Asian order. From the Chinese point of view, Tokugawa Japan and Chosŏn Korea were barbaric and on the margins, but from the perspectives of the two countries, they certainly recognized themselves as the centers. On the basis of the dynamism of historical events, thoughts, and notions between Tokugawa Japan and Chosŏn Korea in the eighteenth century, this research will examine multi-layered perspectives of the individual Japanese and Koreans who played essential roles in diplomacy. How were those officials representing the two states aware of their peers, and how did these notions affect the modern history of the two countries? This question is consistently engaged in this thesis, and to answer it the research will be further explored.
