Abstract
This study analyzes tourism-related data in Nagasaki City and proposes a method to examine how various information sources, such as newspapers, television, websites, and social networking services (SNS), influence travelers to information about restaurants, events, experiential programs, facilities, and transportation. Additionally, a method for evaluating the degree of adequacy or insufficiency of information for travelers is proposed. The analysis was conducted using the results of an online questionnaire survey conducted by Nagasaki City targeting tourists. The findings reveal that information sources with a minor influence on travelers during their trips include "transportation company websites (railways, buses, airlines) ", "personal blogs", "video-sharing platforms (e.g., YouTube) ", and "newspapers". Conversely, information sources with a significant influence include "travel guidebooks", "family, relatives, and acquaintances", and "pamphlets obtained during the trip". Furthermore, the study identified that information about "restaurants and gourmet options", "travel routes and transportation", and "costs" is insufficient during travel, highlighting the need for specific improvements in these areas.
