As for subdivisions, the head of a Kwobetsu family had the title of omi (grandee) and the head of a Shimbetsu family that of muraji (chief). Thus, the organization of the State depended primarily on the principle of ancestor worship. The sceptre descended by divine right without any regard to its holder's competence, while the administrative posts were filled by men of the same race with a similar hereditary title. Aliens like the Yezo, the Tsuchi-gumo, and the Kumaso were either exterminated or made slaves (nuhi). THE TERM "YAMATO" As to the term "Yamato," it appears that, in the earliest times, the whole country now called Japan was known as Yamato, and that subsequently the designation became restricted to the province which became the seat of government. The Chinese, when they first took cognizance of the islands lying on their east, seem to have applied the name Wado--pronounced "Yamato" by the Japanese--to the tribes inhabiting the western shores of Japan, namely, the Kumaso or the Tsuchi-gumo, and in writing the word they used ideographs conveying a sense of contempt. The Japanese, not unnaturally, changed these ideographs to others having the same sounds but signifying "great peace." At a later time the Chinese or the Koreans began to designate these eastern islands, Jih-pen, or "Sunrise Island," a term which, in the fifteenth century, was perverted by the Dutch into Japan. THE FIRST NINE EMPERORS In attempting to construct coherent annals out of the somewhat fragmentary Japanese histories of remote ages, the student is immediately confronted by chronological difficulties. Apart from the broad fact that the average age of the first seventeen Emperors from Jimmu downwards is 109 years, while the average age of the next seventeen is only sixty-one and a half years, there are irreconcilable discrepancies in some of the dates themselves. Thus, according to the Records, the eighth Emperor, Kogen, died at fifty-seven, but according to the Chronicles he ascended the throne at fifty-nine and reigned fifty-six years. Again, whereas the ninth sovereign, Kaikwa, is by the Records given a life of only sixty-three years, the Chronicles make him assume the sceptre at fifty-one and wield it for fifty-nine years. Such conflicts of evidence are fatal to confidence. Nor do they disappear wholly until the beginning of the fifth century, at which time, moreover, the incidents of Japanese history receive their first confirmation from the history of China and Korea.
