This paper focuses on historical revisionism as a factor explaining the phenomenon that contemporary Japan's chauvinistic movement is picking old comer Korean residents in Japan as the main target of attack. We try to clarify the relationship between chauvinistic discourse / movement with history revisionism. First, historical revisionism regards the Japanese Imperial Army’s “comfort women” as a false allegation, and the Korean people and Korean residents in Japan are unduly condemning Japan. Also, the historical revisionism on colonial rule creates the recognition that Koreans in Japan live in Japan without just cause. These perceptions serve as a subjective reason for the rightwing chauvinists to justify their arguments. Second, ethnic discriminatory prejudice against Korean residents, which has close ties with chauvinism movement, acts as the basis for historical revisionist claims. The testimony of former “comfort women” victims will be denied as being untrustworthy because Koreans are “freeloaders” and “liars”. Thirdly, some of the main players of the chauvinistic movement are also committed to the historical revisionist movement, and this fact suggests close ties between chauvinism and historical revisionism in terms of personal connections of the movement. In contemporary Japan, the sense of crisis against the spread of historical revisionism is never widely shared. This is a matter of deep concern in considering the future of exclusionism in Japan.
