Several problems of risk communication and uncertainty are pointed out from experience of Great East Japan Earthquake. Some suggestions are discussed as below to improve issues. Risk communication must be placed under risk governance. Preliminary education is required to improve people's information gathering behaviors just after the earthquake strike because of making people's “disaster awareness” faster and conquering psychological normalizing bias. Attitudes for purchasing food in affected area are different between residences in Tohoku and Tokyo. Distinguishing the nature of probability is needed to discuss uncertainty problems in risk assessment, i. e. probabilistic safety assessment.
