Keywords:Vision for a Digital Garden City Nation, Digi-den Koshien, Topic Model, Latent Dirichlet Allocation, Regional Revitalization

The aim of this study was to classify initiatives presented at the Digi-den Koshien (National Championship for Achieving a Digital Garden City Nation) using Latent Dirichlet Allocation and to provide an overview of their trends. The Digi-den Koshien is held to promote the Vision for a Digital Garden City Nation by soliciting examples of local problem solving using digital technologies from companies and organizations, and awarding outstanding initiatives to encourage their further development. Based on the textual content of the initiatives, a topic model was constructed. The characteristics of the award-winning initiatives were then examined using the model.
