Previous studies show that Japanese people have both interest and concern in the environment and its problems, and that their interest and concern, however, does not necessarily drive them to actions to solve the problems. The purpose of this study is to find a way to leading students into taking action on the environmental problems from the food preparation instructors' point of view. For analysis, a questionnaire was sent to 142 food preparation instructors to ask about teaching of environmental issues in their food preparation class. Findings show that it is important to increase the students' awareness of the environmental impact of food purchased for preparation, and that the students should purchase foodstuff before their class starts.
