This paper is an analysis on the komunsahag of Ogyu Sorai, founded by Sorai and succeeded to his disciple Dazai Shundai, based on 『The Essentials of Reading Japanese』. Sorai argued that the Six Classics written in Chinese should be read in Chinese. He concluded that reading Chinese classics in Japanese was no more than a translation study. However, Sorai's disciple Dazai Shundai who succeeded his interpretation of the classics and political application studies wrote『The Essentials of Reading Japanese』. Shundai accepted the reality Japanese were met with and decided that the Chinese classics could be understood through Japanese reading. He attempted to correct the problems of reading the classics in Japanese to the extent of creating a Shundai dot, Therefore, Sorai and Shundai had different views on reading Chinese characters in Japanese. This could be said as the difference in point of views on Japanese. Such ideological management of Shundai should be thought as from the view of the successor of Sorai School in an attempt to complement the faults of the Sorai School.
