Keju(Civil Service Examination), When it was first instituted during the Sui-Tang Period (6[90bb]-10[90bb] Century. A. D.), was formally called Koukyo(gongju in Chinese pronunciation). It was not until the song dynasty that it was gradually called Keju. It is quite a common impression to the general public, even to some scholar, that keju has never existed in Japan. But if we examined the codes and statutes and its operation of the first half of the Eighth Century Japan, we found that in Japan the keju (Civil Service Examination) did happen and was call koukyo, just like that of Tang times. There was a distinction between gong and ju. Gongren were the scholar candidates(including local school students and common people) recommended by local government to the central government for examination. Juren were scholars who either studied at the Imperial Academy or summoned by Special Edit. These practices were working both in Tang China as well as in Japan. Only the difference lies in the rise of sinzi Group in Tang and shyusai Group in Japan as a result of the Examinations. The shyusai Group distinguished themselves in the category of the writing of Strategy and policies in the Examination. When around the Tenth Century, this category of Examination had become a necessity for all the aspirant scholars attending the Civi Service Examination and also degenerated into a formality. The defects and corruptions out of this practice destroyed the fairness of the whole Examination system, consequently it became useless politically. It has become obsolete after the Edo Era (the 17[90bb] Century) and thus contributed to the general impression that the keju never existed in Japan.
