In recent years, the declining birthrate and aging population have been accelerating in Japan. Municipalities need to utilize data and provide evidence-based policymaking (EBPM) to maintain and improve the quality of resident services with limited resources and financial resources. Therefore, we aim to utilize open image data for tourism appeal in local governments through industry-government-academia collaboration. Currently, the utilization of open image data is not progressing in local governments due to problems such as portrait rights and privacy of images. Therefore, we transfer the image data style, consider the anonymization of the image, and aim to utilize it for tourism. Also, we verified the image style transfer results through demonstration experiments in a local government. As a result, this study demonstrates the feasibility and effectiveness of the proposed approach to local government image data. We believe that this will lead to the utilization of open image data. Furthermore, we aim to deepen the understanding of artificial intelligence technology and the utilization of images in local governments.
