Abstract
Japan has recently been experiencing an ageing society, and the population of local areas is declining. Therefore, it is necessary to promote local revitalization. The purpose of this research is to develop the tourism industry, which is one of the local revitalization measures. At the stage of tourism planning, it takes a lot of effort to build a tourist route by oneself. Namely, it is necessary to specify the purpose of travel from vague interest in travel and select tourist destinations accordingly. It is important to improve the satisfaction level according to the interests of individual tourists, considering the synergy effect that can be obtained by visiting and experiencing related tourist spots. This paper analyses the relationship between travel purposes based on vague interest in travel and proposes the framework of tourist route recommendation with these relationships as the synergy effect.
