The purpose of this study is to identify structural model of food related risk perception by Structural Equation Modeling. In a preliminary study, we reinvestigated the factors that influence on the perceived magnitude of risks with laddering method survey in Japan, Korea and U.S., and established a hypothesis on the structural model of public risk perception. In this study, data were collected in Japan (N=1,185) with the questionnaire we developed. As a result, the fit indexes of the structural models of 5 hazards were good. This models were composed of 3 categories of factors; perceived risk/hazard characteristics (graveness of health injury, accumulation in body and delay of effects, difficulty of control and avoidance, benefits), perceived personal factors (knowledge, conjures images) and perceived social factors (information exposure, trust for regulatory measures, experts and business operators). Information exposure and conjures images have a impact in enhancing perception of graveness of health injury and magnitude of risk.
