In the late 1980s and early 1990s, there was a bottleneck in Japanesefolklore. In order to break the deadlock, the third generation of Japanesefolklore scholars, led by Shimamura Takanori and Yutaka Suga, proposed a newtheory of Japanese folklore research by focusing on the concept of vernacular.They redefined “folklore” through vernacular and used vernacular as a researchmethod, i.e., to study “folk” from the perspective of vernacular. On this basis,this paper examines the Bonnbori Maturi in Japan from the perspective ofvernacular. It is found that the birth and development of the Bonnbori Maturihas reconstructed the Inheritance, breaking the explanatory framework ofthe folklore theory of Inheritance. At the same time, unlike the “top-down”approach of the government and local organizations to revitalize the localeconomy, the Yuwaku-Onsen Street has adopted a “down-top” approach torevitalize the economy by keeping everything as it is and not overly promotingthe anime.
