Good impression of Japan and tourism-purpose ratio of visitors from mainland China, South Korea, and Taiwan

抄録

Japan has the lowest growth rate of GDP out of the seven developed countries. The main reason is as follows, namely many kinds of resources are concentrated in the urban areas such as Tokyo and Osaka. On the other hand, rural resources are scarce and the consumption effect by foreign visitors to Japan is expected in the areas. The visitor numbers from mainland China, South Korea, and Taiwan to Japan account for more than half of the total number of foreign tourists. This paper describes the relationship between the percentage of a good impression of Japan (or percentage of people who like Japan the most) and the tourism-purpose ratio of the visitors from these three areas. The coefficient of determination (cd) is introduced in the relationship between those ratios. As a result, large coefficients are obtained in the cases of South Korea and Taiwan, and the tourism purpose ratio could be predictable with high reliability using a regression equation by examining the good impression ratio in those two areas. The cd for China is small and it is difficult to predict the ratio using a regression equation. It is effective to adopt other methods such as artificial intelligence (AI) to predict the tourism purpose ratio because there are many factors between Japan and China.
