Japan is a very mountainous country. For this reason hardly twelve per cent. of her total area is cultivated. In general the land gradually ascends on both sides as it recedes from the ocean, at first forming hills and table-lands, and then huge mountains. Thus a chain of mountains is formed in the center of the islands, extending throughout the whole length of the empire. The mountains are nearly all of volcanic origin, which accounts for their jagged appearance. There are many active volcanoes, continually sending up great clouds of smoke, and occasionally emitting streams of fire and molten lava, deluging the whole neighborhood with sulphur and ashes. One of the first sights that greets the traveler from the West as he approaches Japan is the smoke of a volcano, ever active, on Vries Island, in the entrance to Yokohama harbor. The chief volcanoes active at present are Asama, Shirane-san, Bandai-san, Aso-san, and Koma-ga-take. I shall never forget the ascent of Asama at night, in 1894. The volcano had been unusually active recently, and a large part of the crater had fallen in, completely changing its appearance. The sulphurous vapors and smoke came up so thick and fast that we dared not approach near the crater for fear of {12} suffocation. At that time we could not see down into the crater at all, but occasionally one can see the blue-red flames curling and writhing far down in the bowels of the earth like a sea of fire, a veritable gate of hell. Of extinct volcanoes Japan boasts a large number. The mightiest of these is the peerless Fuji-san, the pride of every Japanese, the highest mountain in Japan. It is 12,365 feet high, and snow is found on its summit at all seasons. This mountain is now a huge pile of ashes, lava, and boulders--apparently harmless. As late as 1708 it was in eruption, and when I stood on its snowy summit in August, 1893, there were certain places where vapors hot enough to cook an egg came up from the ground. For aught we know, it may at any time burst forth again and devastate whole provinces. This is a land of earthquakes. The records show that from earliest times this country has been subject to great ruin by their visitations. Whole villages and towns have been suddenly swallowed up, and huge mountains have disappeared in a day. These earthquakes are of frequent occurrence. The seismic instruments now in use throughout the empire record about three hundred and sixty-five per year--one for each day. Certain localities are much more exposed to them than others, although none is {13} entirely free from them. These disturbances are very destructive of life and property, especially injuring railways, bridges, and high buildings. They have left their mark upon the whole country. Through the effect of volcanoes and earthquakes together, the surface of Japan presents an appearance seldom seen in any other land.
