JAPAN may be considered the home of the volcano and the earthquake. Few months pass there without one or more earth shocks of considerable force, besides numerous lighter ones of too slight a nature to be worthy of remark. Japanese histories furnish many records of these phenomena.

There is an ancient legend of a great earthquake in 286 B.C., when Mount Fuji rose from the bottom of the sea in a single night. This is the highest and most famous mountain of the country. It rises more than 12,000 feet above the water level, and is in shape like a cone; the crater is 500 feet deep. It is regarded by the natives as a sacred mountain, and large numbers of pilgrims make the ascent to the summit at the commencement of the summer. The apex is shaped somewhat like an eight-petaled lotus flower, and offers from three to five peaks to view from different directions. Though now apparently extinct, it was in former times an active volcano, and the histories of the country mention several very disastrous eruptions. Japanese poets never weary in celebrating the praises of Fuji-san, or Fuji-yama, as it is variously called, and its conical form is one of the most familiar in Japanese painting and decorative art.

As Japan has not yet been scientifically explored throughout, and, moreover, as there is considerable difficulty in defining the kind of mountain to be regarded as a volcano, it is impossible to give an absolute statement as to the number of volcanoes in the country. If under the term volcano be included all mountains which have been in a state of eruption within the historical period, those which have a true volcanic form, together with those that still exhibit on their flanks matter ejected from a crater, we may conclude that there are at least 100 such mountains in the Japanese empire. Of this number about forty-eight are still active.

Altogether about 232 eruptions have been recorded, and of these the greater number took place in the southern districts. This may perhaps be accounted for by the fact that Japanese civilization advanced from the south. In consequence of this, records were made of various phenomena in the south when the northern regions were still unknown and unexplored.

The most famous of the active volcanoes is Asama-yama in Shinano. The earliest eruption of this mountain of which record now exists seems to have been in 1650. After that it was only feebly active for 133 years, when there occurred a very severe eruption in 1783. Even as late as 1870 there was a considerable emission of volcanic matter, at which time also violent shocks of earthquake were felt at Yokohama. The crater is very deep, with irregular rocky walls of a sulphur character, from apertures in which fumes are constantly sent forth.

Probably the earliest authentic instance of an earthquake in Japan is that which is said to have occurred in 416 A.D., when the imperial palace at Kioto was thrown to the ground. Again, in 599, the buildings throughout the province of Yamato were all destroyed, and special prayers were ordered to be offered up to the deity of earthquakes. In 679 a tremendous shock caused many fissures to open in the provinces of Chikuzen and Chikugo, in Kiushiu; the largest of these chasms was over four miles in length and about twenty feet in width. In 829 the northern province of Dewa was visited in a similar manner; the castle of Akita was overthrown, deep rifts were formed in the ground in every direction, and the Akita river was dried up.

To descend to more recent instances, in 1702 the lofty walls of the outside and inside moats of the castle of Yeddo were destroyed, tidal waves broke along the coast in the vicinity, and the road leading through the famous pass of Hakone, in the hills to the east of Fuji-yama was closed up by the alteration in the surface of the earth. A period of unusual activity was between the years 1780 and 1800, a time when there was great activity elsewhere on the globe. It was during this period that Mount Unsen was blown up, and from 27,000 to 53,000 persons (according to different accounts) perished; that many islands were formed in the Satsuma sea; that Sakura-jima threw out so much pumice material that it was possible to walk a distance of twenty-three miles upon the floating debris in the sea; and that Asama ejected so many blocks of stone—one of which is said to have been forty-two feet in diameter—and a lava-stream sixty-eight kilometres in length.

In 1854 an earthquake destroyed the town of Shimoda, in the province of Idzu, and a Russian frigate, lying in the harbor at the time, was so severely damaged by the waves caused by the shock that she had to be abandoned. In 1855 came a great earthquake which was felt most severely at Yedo, though its destructive power extended for some distance to the west along the line of the Tokaido. It is stated that on this occasion there were in all 14,241 dwelling houses and 1,649 fire proof store houses overturned in the city, and a destructive fire which raged at the same time further increased the loss of life and property.
