This study predicted developments in the Fukuoka Itoshima area where large-scale development would be expected in the near future. The purpose is to support the decision-making to the administrative official who performs measures against the development act. To predict, we prepared the data of a past development act. And the Decision-Tree algorithm is used to make the development-predicting model. This model is applied to the Itoshima area, and the development-predicting was done according to three scenarios. As a result, the change in the land use based on these scenarios could be seen. And the effect of measures could be understood at the plan stage.
