Abstract
In this study, we clarified the factors that create core fans in the anime fan community using a combination of atypical and standardized questionnaires. 28 people were asked to fill out an atypical questionnaire using a web form to extract factors that maintain interest, and 72 people were asked to fill out a standardized questionnaire to investigate the degree to which each factor is affected by the community. The results showed that the quality of the story and structure, the quality of the music and BGM, and the implementation of official events had a particularly strong influence on the continuation of interest. Based on these findings, we proposed two strategies for creating core fans in the anime fan community. In the future, we plan to conduct a survey and analysis focusing on those with crowdfunding experience to investigate factors that prevent the decline in engagement of core fans, and to scrutinize methods of return and information dissemination.
