This study proposed a methodology for training university students to become enactors of consumer education in a consumer citizen society. The methodology was based on a diagram of consumer civil society education informed by the collaborative approach of three organizations. The study explored the possibility of developing proactive behavior in students who practice consumer education volunteer activities by analyzing their participation in the Okayama Prefecture Consumer Affairs Center project. The results showed the students in the group who developed changed their behavior in terms of improving their own consumer life, actively communicating information to others, and passing on their behaviors. This suggests that university students who engage in consumer education activities may become "enactors" of this mindset.
