The discourse of Joseon-kukminmunhak intend to blend in korean and japanese living korea, and plan to make a new identity. Japanese demand to be study japanese identity of a korean. but korean take the ground that the discourse of Joseon-kukminmunhak has to seek for originality of Joseon-kukminmunhak. Korean and japanese don`t have methods of bridging the gap of a difference of viewpoint. What was interesting, the process of development in the discourse of Joseon-kukminmunhak, is that Korean`s theory is more bold and delicate than Japanese`s. This is why as follows. Firstly, Japan don`t fight against China and America without Korean`s helping under the Total war. secondly, Japanese don``t give a universal truth as regional hegemony to korean. That`s why Korean lead the discourse of Joseon-kukminmunhak. But discourse of Joseon-kukminmunhak works as covering up a unfair relationship between Korean and Japanese.
