In this study, we investigated the sense of presence through text mining and emotional analysis. Our hypothesis is that online tours with high ratings（ many stars and positive feelings）include the word “Rinjou”（ which indicates the sense of presence）. As a result of emotional analysis, the positive rate significantly increased for the reviews that contained a sentence with the word “Rinjou.” The result suggests that the sense of presence correlates with positive feelings toward participating in online tours. It is also inferred that the form of participation is an important factor in enhancing the sense of presence. For instance, having multiple people participate, such as family members, can lead to the sense of presence. The role of online tours is expected to change as real travelers return after the coronavirus pandemic. Nevertheless, online tours will continue to be important in the tourism market, and we need to analyze how to increase their value.
