Rural areas

In this paper, the decision-making regarding house use of owners of vacant houses in rural areas was analyzed by the method of system thinking. While the number of vacant houses is increasing in rural areas, there is a problem of vacant house owners not tending to make their house a rental or sale property. The longer a house is vacant, the more decay the house will undergo, making it moredifficult to utilize. Therefore, interviewing owners of vacant houses and people working on fostering increased use of vacant houses, a dynamic model (causal loop diagram) of system thinking about the decision-making of the owners illustrated how the value of vacant houses declined. As a result of analyzing the causal loop diagram, the following three points were revealed: 1) as the vacancy period becomes longer, an owner tends to leave vacant houses, strongly intending to dispense with the house; 2) the stronger the ties an owner has with the neighboring areas of the vacant house, the longer the house tends to remain vacant; and 3) if there are no communities left in the neighborhood of a vacant house, there is a high possibility that vacant houses will be left abandoned.
