By tracing back the Japanese "military God" culture, we can investigate the "image degradation" of the militarism history of symbolic statues in contemporary times. Specifically, after World War Ⅱ, Japan realized the emotional acceptance of "World War Ⅱ military God" from "divinity" to "personality" through the image deduction of Yamamoto Isoroku, the commander of the Japanese navy joint fleet in many World War Ⅱ movies, who became an "anti-war" peacemaker beautified by the movies, thus diluting its war crimes. Under the current trend of Showa nostalgia, the rebirth of Japan's "World War Ⅱ military God" on the screen has triggered the evocation of the humiliation of defeat and the inheritance of "post memory". The historical figures and "field of memory" related to World War Ⅱ are deliberately distorted, tampered with or selectively forgotten by different Japanese medias in their emotional guidance, and eventually become the "anti-memory" of historical memory.
