There is also historical experience within Japan of coal-mining cities, such as Yubari in Hokkaido and Omuta in Kyushu, that have struggled financially after Japan's energy system moved away from coal in the 1970s and domestic coal mines closed. To provide protection against coastal erosion, thereby reducing threats to the critical roadway. It was not drafted from the viewpoint of integrated management of the coastal zone. In the following sections we will examine the current status of Japans coastal zone relative to the three functional aspects of coastal zones important to humans mentioned above-disaster prevention, human utilization, and provision of ecological services.
