The pandemic of COVID-19 has not reached convergence yet. Risk perception and willingness to cooperate measures are important for preventing the spread of infection. This study aimed to clarify the factors affecting preventive behaviors against COVID-19 infection. A questionnaire survey was conducted both in prefectures under special warning status and other prefectures and 256 responses were analyzed by structural equation modeling. As a result, people who checked the information by governments and trusted the government tended to have high normative awareness and to refrain from going out. People who have government information and higher knowledge about COVID-19, higher financial distress, or greater anxiety for unknown risk highly perceived the risk of COVID-19. Those people frequently implemented preventive measures. In thirteen prefectures under special warning status, the anxiety of unknown risk directly affected the frequency of countermeasure implementation and going out.
