This study focuses on the disaster risks and countermeasures at the 12 home stadiums of the Japanese professional baseball. Based on the verification with hazard maps, many stadiums are located on the hazardous area. However, there is a lack of information about it toward visitors around the stadiums. Our questionnaires to the managers of each stadium indicated that their risk perception related to natural disasters are not necessarily consistent with hazard maps, and their intension whether they open stadiums as a shelter in the time of disasters depend on the stadiums. More collaboration will be needed with local governments.
