통일초(統一初) 신라(新羅)-일본(日本) 교류와 ‘東萊斷層’路 = Silla-Japan Diplomacy and Dongnae Fault Way

다국어 초록 (Multilingual Abstract)

Shilla, which was unable to give up the efficiency of waterway transportation in receiving supplies, mainly used Ulsan Port. Unlike freight transportation, the envoy made safety a priority and used Busan Port. There was a reason. First, Tsushima Island was the immigration window of Japan. It was difficult to sail from Ulsan to Tsushima Island due to the direction of the Kurushio Current flowing from the south to the north. However, the route between Busan and Tsushima Island was stable.
There was a separate port in Geumgwan Gaya. It was a Tatara(多多羅:다대포) port in Busan.
In 843 Japanese Soldier guarding the northern coast of Tsushima Island witnessed a sparkling light toward Busan in the evening.
The lighthouse is thought to have served as a guide for ships from Tsushima Island to Busan when the relationship between Silla and Japan was good. There was a reason for active exchanges between the two countries at that time. In 672, the interests of Silla and Japan matched. Silla, which was at war with Tang China, tried to eliminate uncertainty in Japan. Japan wanted Silla to be a breakwater to stop the expansion of Tang China.
The first stop by the Japanese envoy who arrived at Busan Port was Dongnae Hot Spring, and they took a rest here and stayed for a day at the Ryeongch temple in Ulsan, and headed to Silla Capital.
In 2011, excavation of the Yeongchwi temple was carried out. There were traces of many buildings that appeared to be residential spaces. I would like to see the temple as a hotel facility for Japanese envoys. In 703, 204 Japanese envoys entered Silla. If Ulsan was a port of supplies for the Silla Kingdom, Busan was a port of diplomacy negotiating with Japan.
