There is much speculation, but no certainty, regarding the origin of the Japanese people. It is, however, generally held that the Japanese race is made up of two main elements—one Mongolian, which came to Japan from Northern Asia by way of Korea, and the other Malayan; a third strain being possibly supplied to some small extent by the Ainu aborigines, whom the invaders found in occupation of the country. The prevailing type of feature is Mongolian, though scientific research claims to have discovered traces of the physical characteristics of other Asiatic races.

The Great Reform gave its name to the first year-period of Japanese chronology, and to Japanese history its first certain date. It was the outcome of a movement having for its object the repair of the authority of the Throne, which had been weakened by the separatist tendencies of the Sōga family. The new form of government then established, in imitation of changes made under the T’ang dynasty in China, was a centralized bureaucracy.
