This study of the globalization era in which the physical boundary between nations collapsed is necessary at the present moment when mutual psychological boundaries become meaningless. This situation is gradually being restructured mainly by soft power from the power relations of the past which was influenced by military power and economic power.
Therefore, in this paper, I will study soft power which was not well researched in Korea. Several results will be reported through questionnaire survey on the influence of soft power especially thought by university students in Korea and Japan.
As a result, it turned out that soft power will be in charge of an important role in the future era if hard power is the indicator of the power of the country so far. Power moves according to the flow of the times. This also changes the awareness of companies in other countries we knew. Especially linguistic expression (linguistic behavior) is strongly positioned as an intermediary of soft power.
