Thenation Japan is constantly imagined, invented, contested and transformed through various cultural practices, such as national policy documents, economic and trade activities, interpretation activities, and media presentations related to Cool Japan Strategy. As the representative strategy on overseas promotion of Japanese culture, Cool Japan Strategy has developed into a systematic cultural process which is actively coordinated by the interpretation and definition of various departments of the Japanese government, the participation of nongovernmental people, the deep cultivation of foreign practitioners, and the publicity of media. Its approaches, mechanism and lessons are of great significance to Chinas strategy of cultural going out.

Key words: Cool Japan Strategy, nation building, overseas promotion of culture, public private collaboration mechanism
