Studies of risk perception in this paper help the judgments people make when they are asked to operate communications of PR and advertisement after the Japanese disaster. This paper also provides a basis for understanding and anticipating public responses to disaster, and improving the risk communication, how people think about and respond to risk. This work tries to describe and investigate media access, media evaluation and trust, structure of impression and risk perception by general consumers in three countries Korea, Taiwan and China after the Great East Japan Earthquake in 11 March 2001. The risk structures of this paper suggest why Korean reception was negative and Taiwanese positive. This structure shows Chinese reception was a fusion of these two countries as well.
