The Arte Piazza Bibai, the Bibai Art Plaza, is a sculpture park in the mountains where forty sculptures of Kan Yasuda, an internationally renowned sculptor, are exhibited. The project was initiated by the City of Bibai and Kan Yasuda in 1992 to revitalize the city with arts and cultural promotion, as well as to preserve old architectures and the surrounding nature. Bibai, once one of the largest coal mining cities, has been suffering from critical depopulation. The art plaza, including the restored closed-down school facilities and the studio, is currently managed by the NPO.
