For what purpose is the construction of protective walls and other artificial matter being undertaken along our coastlines? The sight of our coastlines brings this question out of many people. Answering this question immediately will probably won't lead to much and probably won't solve the problem. First lets look deeper into the roots of the problem and think about what has actually been constructed. As an example, we'll take a look at the construction on the Setohama beach in Chiba Prefecture.

The scale of disasters brought about by earthquakes, volcano eruptions, tanker collisions and other incidents are measured by the quality of disaster preparation and the post disaster response. What kind of flexible training should be prepared to help us respond to critical disasters in the future, of which we have no chance of accurately predicting? It is here that I would like to introduce you to computer age simulation training.

For over 10 years the seemingly drab wet sand of Sanbanze has pitted developers and citizens in a battle over Chiba's development proposal for the tidal flats. Of course this isn't the only deep-rooted battle of its kind. Indeed, under similar conditions to Sanbanze, there is a case overseas where the strong fight of local people and groups has seen a move towards the protection of the environment and the development of a restoration plan. In view of considering the future of Sanbanze Tidal Flats, California's Bolsa Chica story makes a valuable guide to the road ahead.
