Introduction to the importance of coastal area in Japan. Living . On the other hand, one of the characteristics of the sandy beach is that rapid response can take place in reaction to changes in wave field and sand supply, because the sandy beach is composed of a collection of grains of sand, the positions of which can be freely changed depending on wave action, https://doi.org/10.1142/9789813146259_0002, https://doi.org/10.1142/9789813146259_0003, https://doi.org/10.1142/9789813146259_0004, https://doi.org/10.1142/9789813146259_bmatter, Sample Chapter(s) 14, contains four geospatial layers (.GeoJSON) and a README file.

Healthy coastal ecosystems are vital to healthy coastal zones. Replenishing lost coastlines in a way that does not cause more environmental damage is a challenge facing many low-lying countries. The landscape here has the underpinnings of recovery but still feels largely decimated: housing foundations lay bare while weeds and wildflowers grow chest-high. Coastal erosion is a problem of utmost importance in Japan because coastal erosion compromises the ability of coastal zones to act as front-line defenses against floods, tsunamis, and rough seas, to provide adequate utilization functions, and to maintain the integrity of shallow water ecosystems.

Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Comparison of those cities, towns, and villages which border coast lines with those which are landlocked in terms of their area, population, value of industrial shipments, and value of commercial sales shows that despite the fact that waterfront municipalities do not exceed 32% of the total area, they account for 45% of the population, 47% of the value of industrial shipments, and 77% of the value of commercial sales.
