There are many reasons for the development of Japanese animation industry. One of the most important reasons is that Japanese animation style is more suitable for the audience with emotional expression in eastern countries, which may be related to the cultural differences between East and West. In addition, Japanese animation can well grasp the difference between surrealism and reality, and make it perfectly combined with science fiction or magic factors. Japanese animation pays attention to spiritual problems, which is reflected in people's emotional life. Japanese animation pays special attention to the depiction of human nature, especially Miyazaki Hayao's works, such as Princess Ghost and Seven Juvenile Delinquents, which tell the story of the reform process of a group of juvenile delinquents after they are released from prison.
In addition, the Japanese government has also promoted the development of Japanese animation industry to a certain extent. For example, when the Japanese government wants to tighten the censorship of cartoons and introduce relevant laws, that is, amendments to the Yangshengtang Regulations, local governments in Japan also stand on the side of the animation industry in a clear-cut manner.
