Anti-Japaneseism (反日亡国論, han'nichi-bōkoku-ron) is a radical ideology promoted by a faction of the Japanese New Left that advocates for the destruction of the nation of Japan. The ideology was first conceived by Katsuhisa Oomori, a member of the New Left, in the 1970s. Extending from anti-Japanese sentiments and viewpoints such as the Ainu Revolution Theory, it claims that "The nation called Japan and the entire Japanese race should be extinguished from the face of the earth".
