Michi-no-Eki are highway stopovers offering comfortable rest facilities and a variety of other high-quality services. Presently, these facilities have been built in great numbers throughout Japan, including Hokkaido. It is expected that the reasons for using Michi-no-Eki change according to the season. For example, because Hokkaido is a cold, snowy region, Michi-no-Eki provide improved safety in winter. A large-scale questionnaire was distributed to Hokkaido Michi-no-Eki users to determine the seasonal usage characteristics of Michi-no-Eki, specifically in summer and winter. User intention data was collected, the usage characteristics in summer and winter were analyzed using cluster analysis methods, and the results were compared. In summer, tourism uses like "sightseeing" and "stamp rally" are prominent. In winter, functions like "resting", "restrooms", and "weather information" were important. The type of information that users requested at Michi-no-Eki also changed from summer to winter. In other words, it became clear that a function shift phenomenon was taking place.
