高句麗의 對倭外交와 東海交涉路-6세기 후반∼7세기 초 고구려·왜·백제 3국의 상호전략에 대한 재검토를 겸하여-

Abstract

Since the year of 570, Koguryo established amicable relations with Japanese Wa through the diplomatic polices, standing against Silla. This thesis intends to examine specific standpoints of Japanese Wa on this Koguryo’s diplomatic relations toward Japanese Wa and changes in the foreign relations of Japanese Wa to see the international strategies of each country connected with Koguryo. Previous studies have not showed a significant interest in the effects of Koguryo’s diplomatic relations with Japanese Wa on the foreign relations of Japanese Wa. This is because Koguryo’s diplomatic relations with Japanese Wa was stopped only after 4years, and all previous studies only have focused on the significances of Koguryo’s diplomatic relations with Japanese Wa on Koguryo’s international strategies. But, as a result of examination, before Koguryo implemented its diplomatic relations with Japanese Wa, Japanese Wa was isolated from the international relations in the Northeast Asia. Japanese Wa was out of isolation after Koguryo became its diplomatic relations with Japanese Wa. Claiming the Koguryo’s approach, Japanese Wa was able to demand Silla to continue the diplomatic relations and get what they wanted. This is why Baekje also resumed their diplomatic relations with Japanese Wa. Due to Koguryo’s diplomatic relations with Japanese Wa, Baekje had to compete with Koguryo for the international relations with Japanese Wa. The amicable relationship between Japanese Wa and Koguryo was reinforced by Japanese Wa regardless of Baekje’s standpoint, and this relationship was limited between Japanese Wa and Koguryo so that it didn’t changed the relationship between Koguryo and Baekje to be hostile. According to the records, Koguryo’s diplomatic relations with Japanese Wa had been suspended for approximately 20 years after dispatching an envoy in 574. However, Koguryo Buddhist monk Hyeja’s visit to Japanese Wa in 595 was accomplished based on close relationship between Koguryo and Japanese Wa, so there had been exchange between two countries for the close relationship during this period of 20 years. With regard to this, Japanese Wa revealed in their international strategies that they responded to the approach of Koguryo in order to press target countries for negotiation and accomplish their intention using their diplomatic relations with Koguryo. Followed by the appearance of Sui Dynasty, an accident which stirred up the Northeast Asia was a confrontation between Sui Dynasty and Koguryo. With regard to this critical international situation, it has been considered in our understanding so far that Japanese Wa responded to the Koguryo’s international strategies. Japanese Wa’s message to Sui Dynasty in 608 turned the countries for negotiation. But, Yang, emperor of Sui only dispatched an envoy to understand the fact, but didn’t take any follow-up actions. This is why even a group of envoys from Japanese Wa who could have been victimized was able to return to their home country after completing their mission. In this respect, it is impossible to agree with the understanding that examined in the connection between Japanese Wa’s diplomatic relations with Sui Dynasty and the international strategies of Koguryo. Therefore, it is necessary to consider that Japanese Wa’s diplomatic relations with Sui Dynasty was due to the decision and intention of Japanese Wa that needed the exchange with Sui Dynasty. We can see here that Japanese Wa also applied their international strategies to press target countries for negotiation and accomplish their intention using their diplomatic relations with Koguryo to their diplomatic relations with Sui Dynasty.
