This paper presents the results of a gaming simulation study into how people change their consciousness and behavior as a result of using different forms of community currencies. In recent years, some studies have examined the effect of community currency use in promoting the local economy and community. These studies suggest that, in order to promote the use of community currency, it is important to form a positive feedback system between consciousness and behavior. However, these existing studies have not considered the difference of the effects brought about by different forms of community currency. In this study, we consider changes in consciousness and behavior that relate to two forms of community currency: paper currency and LETS (Local Exchange and Trading System) currency. We initiated a Community Currency Game, in which we analyzed subject behavior and subjects completed questionnaires. The results are as follows: Paper currency has a larger amount of flow and participants are encouraged to circulate. However, this type of community currency does not form the value of monetary diversity and community oriented value so much. LETS currency forces participants to create opportunities in order to use community currency and create value based on their regional contribution and monetary diversity. However, this type of community currency tends to lead to a closed circle.
