This article examines whether belief in superstitions and folklore differs by age and degree of modernization specifically. This study investigated regional and generational differences in attitudes toward “Luck Resource Belief,” a notion regarding luck. The 500 Japanese participants in our sample were stratified by place of residence, age, and income. The results reflected gender differences, but not regional or generational differences with regard to the “Luck Resource Belief” scale scores. Based on these results, the hypothesis that the mass media plays a major role in the dissemination of information about superstitions and folklore is discussed in this context.
