This study conducts analysis and classification of consumption trends for foreigners visiting Japan using a questionnaire survey of the Japan Tourism Agency. The agency published a topic analysis of tourist consumption trends. However, the analysis only considered the consumption trends of tourists from each country. This study analyzes and visualizes the relationship between consumption trends, visiting rates to Japanese prefectures, and tourist nationalities. We use the questionnaire survey of 19 countries who visited Japan from 2015 to 2017. The questionnaire results are analyzed using self-organizing maps (SOMs). A SOM can visualize the similarity relations between tourist nationalities and questionnaire items, which is difficult to comprehend with simple or cross tabulations. This study illustrates the relationship between foreign visitors, the visiting prefectures, and the consumption trends and expects the future consumption trends.
