Japanese missions to Joseon represent a crucial aspect of the international relations of mutualJoseon-Japan contacts and communication.^[1] The bilateral exchanges were intermittent.

The unique nature of these bilateral diplomatic exchanges evolved from a conceptual framework developed by the Chinese.^[2] Gradually, the theoretical model would be modified. The changing model mirrors the evolution of a unique relationship between two neighboring states.^[3]

In 1377Goryeo envoyChŏng Mong-ju travelled toTsukushi in Japan where he metImagawa Ryōshun;^[4] and the consequences of his efforts were only seen later.

The Muromachi bakufu's diplomatic contacts and communication with the Joseon court encompassed informal contacts and formal embassies. Muromachi diplomacy also included the more frequent and less formal contacts involving the Japanesedaimyo (feudal lord) ofTsushima Island.

In addition, trade missions between merchants of the area were frequent and varied.^[5]

Japanese-Joseon bilateral relations were affected by the increasing numbers of international contacts which required adaptation and a new kind of diplomacy.^[16]
