Wild animals are only moderately abundant, as is natural in a country so thickly inhabited. The black bear is found frequently in the well-wooded mountains of Yezo and the northern part of the Main island. The great bear, called also by the Japanese the red bear, and which is the same as the grizzly bear of North America, is also common in the Kurile islands and in Yezo. The wolf is sometimes found and the fox is common. The superstitions concerning the fox are as remarkable as those in the north of Europe, and have doubtless prevented its destruction. Deer are found in abundance in almost all parts of the islands. They are, however, most common in Yezo where immense herds feed upon the plentiful herbage. The waters around Japan abound in fish. The coast is indented by bays and inlets which give opportunity for fishing. The warm currents flowing past the islands bring a great variety of fish which otherwise would not reach these islands. By far the most common article of food, other than vegetable, is the fish of various kinds and the shell-fish which are caught on the coasts and carried inland to almost all parts. The division of the empire into provinces (_kuni_) was an important step in practical administration, and it is often referred to in these pages. This division was first made by the Emperor Seimu A.D. 131-190, when thirty-two provinces were constituted. The northern boundary of the empire was indicated by a line across the Main island from Sendai bay to a place on the west coast nearly corresponding to the present situation of Ni-igata. North of this line was the acknowledged territory of the Ainos, and even south of it were many tracts which were the disputed border.
