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. The supreme control of affairs was vested in the Council of State. In this Council the Prime Minister presided, and with him were associated the two assistant Ministers of State and the President of the Privy Council. Of the eight Boards, or Departments of State, five dealt mainly, but by no means exclusively, with matters relating to Ceremonial, Religion, the Army, Finance and Taxation respectively; the other three having the direction of business connected more immediately with the Imperial Court. There seems, however, to have been no very clear-cut division of business, Court interests being apparently mixed up with the affairs of every department. This change in the form of government was only one of many results caused by the inrush of Chinese ideas at this time. The influence of the wave of Chinese culture which swept over the country permeated every part of the national fabric, remodelling the social system, and laying the foundations of Japanese law, education, industries and art. Later on provision was made for the establishment of a regency during the minority of a reigning Sovereign, the regent (_Sesshō_) by virtue of his office ranking at the head of the official hierarchy. When the regency expired, the ex-regent assumed the title of _Kwambaku_ (or _Sesshō-Kwambaku_), retaining his official precedence. The two posts were subsequently separated, and, like all other Court offices, became, as the authority of the Court declined, mere honorary titles. Both posts and honorary titles were hereditary in certain branches of the Fujiwara family, the only exception to this rule occurring in the sixteenth century. It was not till the eighth century that the Japanese elaborated a written language of their own. The Koreans had done so already, but the two written languages thus superadded to what was borrowed from China have nothing in common. That of the Japanese consists of two different scripts, each adapted from Chinese characters. The Korean script bears no resemblance to Chinese. Both countries have good reason to regard as a very doubtful blessing the possession of two spoken and two written languages.
