There was no active economic, cultural and human exchange between Goryeo and Japan, as they had no official foreign relationship each other. For this reason, we hardly find any detailed description on the Goryeo dynasty and people of Goryeo in Japanese literary sources except extremely fragmental descriptions. This is due to lack of information exchange between the countries and to a tendency that only brief facts were written in many materials. Therefore, even these fragmental descriptions need to be classified to supplement the deficiency of our materials. There seems to be about 450 mentions of Goryeo dynasty in Japanese literary materials : 245 mentions in 23 diary materials ; 163 in 23 edited materials, 22 in official and private documents, 22 in edited documents, 9 in the preface and postscripts of the books, 15 in marginal spaces. Although there were various types of contents in these mentions, in the most cases there were about commissioners and official letters for the establishment of the foreign relationship, mutual visits, return of drifting persons, and trade of Korean literature and goods. It is not easy to find out the changes of foreign relationship between two countries from the diary materials, as they were too belief. However, they were important tools to confirm the existence of the exchanges between to kingdoms which does not appear in the Korean chronology. Given the fact that the official and private documents and edited documents of Japan mentioned the Goryeo were foreign documents sent to Japan, and that there is no document of Goryeo dynasty left, these Japanese materials are so important in terms of philology. And also from the edited materials, the preface and postscripts of the books, and the marginal space we can find out some aspect of economic, cultural and human exchange between Goryeo and Japan which had no official relationship. Most Japanese descriptions of Goryeo dynasty in their materials, except few, are fragmental mentions about foreign relationship between two nations. Nevertheless, there are important materials as they were never mentioned in the Korean materials.
