Abstract
There has been increasing interest in preventive effect of coastal forests against tsunami especially since the Great East Japan Earthquake. The information about where and how far beaches exist adjacent to coastal reserved forests throughout Japan is essential not only to disaster prevention against tsunami but also to discussion about regional policy on environment and utilization of coasts.
In this study, the location and the length of beaches adjacent to coastal reserved forests, which are not published in national statistical information about coasts, were estimated by using GIS and existing statistical information published by Ministry of the Environment and Geospatial Information Authority of Japan. And, the estimated results were verified by interviewing departments of prefectural governments in charge of coastal management. Problems with management of beaches were also investigated by inter-viewing them about the existence and content of cooperation in areas adjacent to coastal reserved forests with departments in charge of forest management.
