Abstract Japan is experiencing increased diversity due to the rising number of tourists and foreign residents. However, research on diversity ideologies in Japan is limited, and how cultural harmony is fostered remains unclear. The present study explored whether a cultural psychology course promotes identity‐conscious ideologies (multiculturalism and polyculturalism) and positive attitudes toward cultural diversity in Japan. A preliminary analysis of previous data revealed that polyculturalism aligns well with cultural psychology course content. In the main study, a questionnaire was administered to cultural psychology and introductory psychology students before and after the courses to assess the impact of cultural psychology classes on diversity ideologies. Results indicated that while diversity ideologies did not significantly change after the course, polyculturalism was marginally associated with a tendency to enroll in a cultural psychology course. Despite limitations in measurement and design, this study provides valuable insights for institutions aiming to foster acceptance of diversity.
