The Japanese islands are undoubtedly of volcanic origin, and many of the volcanoes in the country are still more or less active. The general conformation of the land leads one to suppose that the islands are the summits of mountain ranges which some thousands of years back had their bases submerged by the rising of the sea or else had by degrees settled down beneath the surface of the ocean. The general characteristic of the country is mountainous, and only about one-sixth of the total area is in cultivation. Fuji-yama, the loftiest mountain, for which the Japanese have a peculiar veneration and which has been immortalised in the art of the country, has an altitude of 12,730 feet. The next in height, Mount Mitake, ascends some 9,000 feet, and there are many others of 5,000 feet or more. Japan has from time to time been ravaged by, and indeed still is subject to, terrible earthquakes. These dire calamities seem to recur at regular intervals. The Japanese islands appear to be in the centre of great volcanic disturbances--a fact which probably accounts for those seismic outbreaks which periodically devastate considerable tracts of the country and cause tremendous havoc to life and property. The written records, extending back some 1,400 or 1,500 years, clearly prove that earthquakes even more terrible in their effects than any that have taken place in recent times were of frequent occurrence. It is, of course, possible that these records may be inaccurate or have been largely exaggerated, but they at any rate tend to show that those great cosmic forces which are popularly termed earthquakes have been constantly at work in Japan ever since any written records have been preserved and no doubt long anterior to that time.
