무로마치 왜구와 조선의 대(對)왜인 정책

Wakou appeared in the early of 13th century. After 1350, Wakou often invaded Goryeo kingdom and caused considerable damage in its society and economy. Goryeo kingdom dispatched an envoy to Japan for the checking of Wakou from 1360’s. In 1370’s, Goryeo kingdom carried out the military sanction in order to check the Wakou aggression. For example, Goryeo kingdom won a signal victory in Jinpo, Hwangsan and Gwanyeumpo through gunpowder weaponry and gone on a conquest of Tsushima. In other words, Goryeo kingdom tried to check Wakou through the power of diplomacy and military. But these polices of Goryeo kingdom hesitated to say positively their success. Because Wakou was not eradicated. Meanwhile, Joseon kingdom adopted a policy that was very amicable toward the Japanese to maintain the peace and the stability. As a result, the number of Japanese that lived in Josenon kingdom increased rapidly as compared with Goryeo kingdom. Joseon kingdom satisfied the demand of Japanese that lived in Josenon kingdom and implemented the friendly police. For example, Joseon kingdom has been settled the Japanese in three ports and carried out the economic aid. Then, these polices needed many economic aid. According to historical records, the total cost of these polices are very similar to the grain supplies that Wakou has plundered from Goryeo kingdom. Ultimately, the economic aid of Joseon kingdom to Japanese is of a degree that Goryeo kingdom is plundered by Wakou. Therefore, the peace of Joseon kingdom is able to be kept by shouldering the economic burden. This is the choice of Joseon kingdom and the peacekeeping cost to the peace of Joseon kingdom and East Asia.
