Recently, local revitalization has become an important issue. Activities to promote tourism, a comprehensive local force, are increasing most significantly. Because dissemination of tourism information is important in attracting tourists, open data is now gathering attention as a means of providing information. In this study, we propose a local PR model for providing tourism information in the form of open API, intended to disseminate tourism information through the content created using the open API. We converted the actual tourism information of Seto, Aichi Prefecture, into open data, in order to create various content using the resulting API; the proposed model was proven to be useful. We also reviewed some issues involved in providing open data, which were found during the process of creating the trial content.
