Recently the third artificial intelligence(AI) boom has come and the relationship between machinery and human beings in various fields such as finance, transportation and education is reconstructed. Though there are several previous researches about smart tourism, there is not efficient research about the relationship between tourism and AI especially not using a sensing log data such as global positioning system(GPS) but a data about tourists’ decision making. Therefore, in this research we lend smart speakers to tourists staying at hotels in Atami, Shizuoka prefecture. From the analysis of those log data and the questionnaire survey, we will discuss what kind of artificial intelligence is required in the tourism field and how artificial intelligence and sightseeing will be involved in the future.
