The ultimate goal of this paper is the establishment of a sustainable local food movement in Japan. In order to achieve this goal, we evaluated the causal structure of consumers' preference to "local foods". A mail survey in the Tokyo metropolitan area was used to collect the data. The results show that consumers' knowledge of Chisan-Chisyou is limited, but they do tend to usually buy local foods. Consumers' preferences for local foods are affected by "safety", "relationship with community" and "interest in agriculture". But, in this model, it can't show the influence of consumers' evaluation at shops, such as brand, freshness and in season or not.
