If the view of recent students of anthropology be correct, that the elements dominating the population in ancient Japan were in the south, Malay; in the north, Aino; and in the central region, or that occupied by the Yamato men, Korean; then, these continental invaders may have been worshippers of Heaven and have possessed a religion closely akin to that of ancient China with its monotheism. It is very probable also that they came into contact with tribes or colonies of their fellow-continentals from Asia. These tribes, hunters, fishermen, or rude agriculturists--who had previously reached Japan--practised many rites and ceremonies which were much like those of the new invaders. It is certain also, as we have seen, that the Yamato men made ultimate conquest and unification of all the islanders, not merely by the superiority of their valor and of their weapons of iron, but also by their dogmas. After success in battle, and the first beginnings of rude government, they taught their conquered subjects or over-awed vassals, that they were the descendants of the heavenly gods; that their ancestors had come down from heaven; find that their chief or Mikado was a god. According to the same dogmatics, the aborigines were descendants of the earth-born gods, and as such must obey the descendants of the heavenly gods, and their vicegerent upon the earth, the Mikado. Purification of Offences. These heaven-descended Yamato people were in the main agriculturists, though of a rude order, while the outlying tribes were mostly hunters and fishermen; and many of the rituals show the class of crimes which nomads, or men of unsettled life, would naturally commit against their neighbors living in comparatively settled order. It is to be noted that in the god-way the origin of evil is to be ascribed to evil gods. These kami pollute, and pollution is iniquity. From this iniquity the people are to be purged by the gods of purification, to whom offerings are duly made. He who would understand the passion for cleanliness which characterizes the Japanese must look for its source in their ancient religion. The root idea of the word _tsumi_, which Mr. Satow translated as "offence," is that of pollution. On this basis, of things pure and things defiling, the ancient teachers of Shintō made their classification of what was good and what was bad. From the impression of what was repulsive arose the idea of guilt. In rituals translated by Mr. Satow, the list of offences is given and the defilements are to be removed to the nether world, or, in common fact, the polluted objects and the expiatory sacrifices are to be thrown into the rivers and thence carried to the sea, where they fall to the bottom of the earth. The following norito clearly shows this. Furthermore, as Mr. Satow, the translator, points out, this ritual contains the germ of criminal law, a whole code of which might have been evolved and formulated under Shintō, had not Buddhism arrested its growth.
