So far it has been highly evaluated the beauty of the perspective of islands, which were located in the Seto Inland Sea. But, recently, we can point out the new movement so as to actively evaluate even the close views of each island. In spite of it, if we pay attentions to the real close views, we often see many ruins of them, because of the difficulty of sustainability for those historical and/or cultural resources as well as natural resources which constitute of the close views of those islands. This paper aims to clarify the cause and effect, which affect to the sustainability of regional resources, by paying attentions to the recent art projects which has been widely introduced here and there in this area. Therefore, taking such three islands as Naoshima, Simokamagari, and Ikuchi islands for our case study, we are to consider comparatively from the following three view-points; 1) Contents of the each project, 2) Relation to the residents in the islands, 3) Influence to the regional resources.
