This study focuses on mutual awareness of Mongolian and Japanese people. We conducted a questionnaire survey on the “Japanese view about the Mongolian” and “Mongolian view about the Japanese” to reveal a current mutual awareness of Mongolian and Japanese people. As a result, it clarified the difference of consciousness among people of two nations. Furthermore, to compare the awareness of inter-generation, we divided the subjects of a survey into two groups, middle-aged and the younger generations, and its results will be discussed in this paper.
