Abstract: As important intelligencegathering personnel, Ninja worked secretly but actively in Japanese Warring States. The mystical image and skillful Ninjutsu of Ninja represented the unique culture of this minority group which was different from traditional culture, and became a new cultural symbol in Japanese culturenurtured country period. Through the research on the typical animation work Mobile Fighter G Gundam, it is found that Ninja is supported spiritually by disguise, tolerance, purity, abandon and other unique moral thoughts. Therefore, Mobile Fighter G Gundam not only shows the unique narrative method centered on historical complex which was presented in Gundam’s works, but also promotes the development of Japan’s animation in its diversity types. It also reveals the image of modern Ninja. The integration between traditional Japan culture and postmodern elements can be seen from another perspective.
