The work supervised by Hayao Miyazaki focuses on describing the struggle between mankind and the natural world, and also reveals the cruelty and ruthlessness of human warfare. The human instinct to pursue survival and happiness is the source of conflict with other races in nature, especially after humans have begun to master higher science and technology. In the writings of Master Hayao Miyazaki, the relationship between people and nature is vividly expressed.
Hayao Miyazaki regards "human" and "nature" as two extremes that can never compromise with each other. He believes that humans must destroy nature in order to survive. In the film, Ashitaka was once in order to coordinate the peaceful coexistence of the two parties. Man and God dealt with each other, but in the end it was also a tragic ending. Both man and God were hurt. Ashitaka also said: "I tried my best to prevent it (referring to the war between humans and gods), but ultimately failed." But regardless of whether the problem of coexistence between man and nature can be solved, the first thing as a human being is to survive. At the end of the film, the death of the unicorn beast god reborn all things, and people have to start a new life. Ashidaka said to Sang: "We want to live together!" The theme of the whole play was reiterated again.
