Since fiscal year 2023, researchers from our foundation have conducted overseas study visits each year from August to October. Traveling to tourist destinations in the United States, Europe, Oceania, and Asia, we have shared observations from these visits from multiple perspectives while considering the directions in which tourism may continue to develop dynamically. In this volume, we focus specifically on Europe, where many advanced initiatives have been undertaken in the field of tourism, and look back on the trajectory of these three years of study visits.
