The Jogan Era - Joganseiyo

A compilation of political discussions between Emperor Taizong of the Tang Dynasty, China, and his ministers, including Wei Zheng and Fang Xuanling, divided into 40 sections, including The Way of the Emperor, Political Form, Wisdom, and Seeking Admonition. 10 volumes. Written by Wu Jing of the Tang Dynasty. Emperor Taizong Li Shimin, known as a great ruler, devoted himself to domestic stability and the restoration of people's power, creating an era of peace known as the Zhenguan era, but he also liked to listen to advice and prevented himself from becoming tyrannical. This book was written during the reigns of Emperors Zhongzong and Xuanzong, who experienced the chaos of the Wuwei disaster, with the intention of making Emperor Taizong's governance a model for others. According to one theory, the first version was created and presented to Jungjong, and then the second version was created at the beginning of the Kaiyuan era (713-741), which was revised and presented to Xuanzong and made public. Since then, it has been widely read in China, Korea, and Japan as a textbook for rulers of the old era. The second version was edited and annotated by Ge Zhong at the end of the Yuan era, and is a collection of critical essays on the book by intellectuals from the Song dynasty, but it is said to contain many errors and omissions, and the order of the chapters is different from that of the original. Harada Taneshige created the "Zhenguan Zheng Yaojihon" (1962) based on copies of the Tangsho version handed down in Japan, and corrected the errors in Ge Zhong's version.

中国、唐の太宗と魏徴(ぎちょう)・房玄齢(ぼうげんれい)ら群臣との政治上の議論を、君道、政体、任賢、求諫(きゅうかん)などの40編に分類、編集した書。10巻。唐の呉兢撰(ごきょうせん)。名君といわれる太宗李世民(りせいみん)は、国内の安定と民力の回復に力を注ぎ、貞観の治とよばれる太平の時代を生み出したが、好んで諫言(かんげん)に耳を傾け、専横に陥るのを防いだ。本書は、武韋(ぶい)の禍(か)の混乱を経験した中宗・玄宗の時代に、太宗の治政を鑑(かがみ)とする意図でつくられた。一説では、最初に中宗に上進した初進本がつくられ、ついで開元年間（713～741）の初めに、改編して玄宗に上進され、世に公にされた再進本がつくられた。以後、旧時代の為政者の教科書として、中国、朝鮮、日本で広く読まれた。通行本は、元末に戈直(かちょく)が校訂して注を施し、宋(そう)代知識人の本書に対する評論を集めた集論本であるが、誤脱が多く、編章も原本の順序とは相違があるといわれる。原田種成(たねしげ)は日本に伝わる唐鈔(とうしょう)本系統の写本などを基にして『貞観政要定本』（1962）をつくり、戈直本の誤りを正した。
