Joseon missions to Japan represent a crucial aspect of the international relations of mutualJoseon-Japanese contacts and communication.[1] In sum, these serial diplomatic ventures illustrate the persistence of Joseon'skyorin (neighborly relations) diplomacy from 1392 to 1910.[citation needed]
The chronology of one side in a bilateral relationship stands on its own. This long-term, strategic policy contrasts with thesadae (serving the great) diplomacy which characterized the Joseon-Chinese relations in this same period.[2]
The unique nature of these bilateral diplomatic exchanges evolved from a conceptual framework developed by the Chinese. Gradually, the theoretical model would be modified. The changing model mirrors the evolution of a unique relationship between two neighboring states.[3] In the 20th century, Joseon's neighborly relations diplomacy failed.
General Yi Sŏng-gye (posthumously known asTaejo of Joseon) established the "Kingdom of Great Joseon" in 1392–1393, and he founded theYi dynasty which would retain power on the Korean peninsula for five hundred years. An early achievement of the new monarch was improved relations with China; and indeed, Joseon had its origin in General Yi's refusal to attack China in response to raids from Chinese bandits.[4] The Joseon foreign policy would evolve from pre-existing foundations. For example,Goryeo envoyChŏng Mong-ju travelled to Japan in 1377;[5] and the consequences of his efforts were only seen later.
As an initial step, a diplomatic mission was dispatched to Japan in 1402. The Joseon envoy sought to bring about the re-establishment of amicable relations between the two countries and he was charged to commemorate the good relations which existed in ancient times. This mission was successful, andshōgunAshikaga Yoshimitsu was reported to have been favorably impressed by this initial embassy.[6] Subsequent missions developed and nurtured the contacts and exchanges between the two neighboring countries.
Not less than 70 diplomatic missions were dispatched from the Joseon capital to Japan before the beginning of Japan'sEdo period.[7] A diplomatic mission conventionally consisted of three envoys—the main envoy, the vice-envoy, and a document official. Also included were one or more official writers or recorders who created a detailed account of the mission.[8] Artists were also included in the diplomatic delegation.
Reciprocal missions were construed as a means of communication between Korean kings and Japaneseshōguns of almost equal ranking. The emperors of Japan at the time were figureheads with no actual political or military power;[9][10] the actual political and military rulers of Japan with whom Joseon communicated were the shoguns who were represented asTycoon of Japan in most foreign communications in order to avoid the conflict with theSinocentric world order in which theemperor of China was the highest authority, and all rulers of tributary states were known as "kings".[11]
The history of Joseon Korea's diplomacy with Japan can be parsed in four parts: (a) before the Japanese invasions in 1592–1598; (b) in the context of the invasion; (c) after the invasion; and (d) in modern times.
The Joseon diplomatic contacts and communication with Japan encompassed formal embassies to theMuromachi bakufu.[12] Joseon diplomacy also included the more frequent and less formal exchanges with the Japanesedaimyo (feudal lord) ofTsushima Island.
In addition, trade missions between merchants of the area were commonplace. For example, more than 60 trade missions per year marked the period from 1450 through 1500.[13]

Diplomatic relations were severed in 1592 when Japanese armies invaded Joseon territory. The ruptured bilateral relations were not restored immediately after the death of Hideyoshi in 1598; the invading forces gradually withdrew from occupied land on the Korean peninsula.[27] By the end of 1598 all Japanese forces had left Korea, but relations would not be normalized until several years later, during the Tokugawa shogunate.

After the Japanese invaders were repulsed, Korean-Japanese diplomatic relations had to be re-established and normalized; they ultimately took on a somewhat different form than prior to 1592.[32] For starters, Japanese envoys/missions were restricted to thewaegwan in Busan and prohibited from traveling to Hanseong (present-day Seoul) by the Joseon court (as the Japanese invasion forces in 1592 used the same land route in Korea as prior Japanese missions had).[33] Further, the missions from Joseon were no longer greeted in Japan by military commanders but only diplomats. Lastly, the costs of the Korean missions were entirely paid for by the Japanese, which by some estimates equaled the Tokugawa shogunate's entire annual budget in the years that they were dispatched.[33]
The Joseon court also did not resume using the termtongsinsa for missions to Japan until the 1636 mission, as the term was only used for missions under conditions of normalized relations.[34]
