We conducted an internet questionnaire survey to clarify the characteristics and grasp the volume of the target of information provision for considering the communication policy and strategy to promote understanding and coping behavior of climate change risk. The analysis showed that the cluster with little interest in climate change, less knowledge, and unclear opinions accounted for more than 40% of all respondents, the cluster with high risk perception and enxiety about climate change and positive attitude toward mitigation and adaptation measures, and the cluster that is skeptical about climate change and do not recognize the necessity of any measures. We thought that the information providing approach to the cluster indifferent to climate change witch is the maximum volume was important. Then we discussed the content of information to promote understanding and countermeasures against climate change. By approaching with appropriate information and communication activities to each cluster with different thoughts and attitudes about climate change, it can be expected that deepening of understanding and positive evaluation and cooperation for mitigation/adaptation measures of climate change.
