Discussion about the foundation of ��Northeast Economic Zone�� is vivid in the situation of active trade and exchange over the national border in the 21st century. That aims to bind the economic trade zone among Korean East Sea, west Sea of Japan, northeast of China, and Russia. However, we need essentially to study more about southeast coast region which constitute the ��East Sea Rim Culture Area�� to bind them. Japan has exerted to establish ��Great East Asia Co-Prosperity Sphere�� taking the policy of maritime sovereignty to expand to Asian continent naming East Sea to Japan Sea from Meiji era.
Korea have discussed and raised the topic about ��East Sea Cultural Sphere��, or ��Northeast Economic Zone�� but there have been few practical discussion for the topic of human and nature or regional relationship among peoples of the area in time series of past, present and future locating the Korean peninsular at the center of the discussion. Until, ancient Silla dynasty has been the center of the question about the exploration of east sea coast. And the view point never viewed from the regional history but from the view point of central power of government. So, this view point naturally influenced to the point of activity stage in Korean history as the capital city moved from Gyeongsang-do province centered at Gyeongju to Gaeseong the central region of the peninsular by the ruin of Silla dynasty and reunification by Goryeo dynasty, which induced recognition of peripheral location for the southeast coast and late development lacking academic research activity about the regional study in Goryeo and Choseon dynasty. But this trend only produced many research results about the damages by the attack of native Japanese pirates during late Goryeo and early Choseon dynasty and about the problems of East Sea or sovereignty of Dokdo.
After the year of 2000, many research institution showed active research result about the southeast coast regional society but they lack collection in literal materials, oral statement, and classification of the materials about the southeast coast region. Now, we need to pay attention about this region again. I suggest a cooperative research activity among the institutions linking related many universities to get more effective research result and collecting important literal and oral materials which might disappear in near future without any attention.
