Japan is a mountaineous country, and coastal areas have been looked upon quite valuable. In most cases, shorelines were slightly advancing until 1950, although there are some exceptional coasts which have been under continuous erosion for more than a thousand years. However, in the last thirty years, beaches began to be eroded one after another, and the countermeasure against beach erosion has become one of the most important problems in the national land preservation. Since the early 1960's, many seawalls against the beach erosion have been constructed. The table shows the amounts of the shore protection works constructed in the last twenty years.
