Abstract
Japan has many remote islands in its territorial waters. The isolation yields intense depopulation under aging society in Japan. Improvement of its life surroundings is important challenge for these arias. Some of researches indicate the necessity of the connection to other area, such as nearby bigger islands or main islands. This study focus on shopping of remote islands residents, especially going out to other areas. This study had a survey in Goto, Nagasaki, and confirmed the resident's activity to other areas for making up their demand for shopping. Then, to examine the transportation policies and the replacement of shopping facilities, this study built the shopping model that can predict the frequency of shopping in other islands in relation to transportation parameters like travel time. The model showed the good fitness for shopping behavior of residents in Goto reasion.
