In short, the Mikado tribe or Yamato clan did, in reality, capture the aboriginal religion, and turn it into a great political machine. They attempted syncretism and succeeded in their scheme. They added to their own stock of dogma and fetich that of the natives. Only, while recognizing the (earth) gods of the aborigines they proclaimed the superiority of the Mikado as representative and vicegerent of Heaven, and demanded that even the gods of the earth, mountain, river, wind, and thunder and lightning should obey him. Not content, however, with absorbing and corrupting for political purposes the primitive faith of the aborigines, the invaders corrupted their own religion by carrying the dogma of the divinity and infallibility of the Mikado too far. Stopping short of no absurdity, they declared their chief greater even than the heavenly gods, and made their religion centre in him rather than in his alleged heavenly ancestors, or “heaven.” In the interest of politics and conquest, and for the sake of maintaining the prestige of their tribe and clan, these “Mikado-reverencers” of early ages advanced from dogma to dogma, until their leader was virtually chief god in a great pantheon.
A critical native Japanese, student of the Kojiki and of the early writings, Professor Kumi, formerly of the Imperial University in T[=o]ki[=o], has brought to light abundant evidence to show that the aboriginal religion found by the Yamato conquerors was markedly different at many vital points, from that which was long afterward called Shint[=o].
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.
