TheAsuka Kiyomihara Code (飛鳥浄御原令,Asuka Kiyomihara-ryō) refers to a collection of governing rules compiled and promulgated in 689, one of the first, if not the first collection ofRitsuryō laws inclassical Japan.[1] This also marks the initial appearance of the central administrative body called theDaijō-kan (Council of State) composed of the three ministers—theDaijō-daijin (Chancellor), theSadaijin (Minister of the Left) and theUdaijin (Minister of the Right).[2]
In 662,Emperor Tenji is said to have compiled the first Japanese legal code known to modern historians. TheŌmi-ryō, consisting of 22 volumes, was promulgated in the last year of Tenji's reign.[3] This legal codification is no longer extant, but it is said to have been refined in what is known as the Asuka Kiyomihararitsu-ryō of 689.[2] The compilation was commenced in 681 underEmperor Tenmu. The Emperor died in 686, but the finalization of the Code took a few more years. It was promulgated in 689. These are understood to have been a forerunner of theTaihō ritsu-ryō of 701.[4]
Although not "finalized" (not incorporating a penal code, aritsu, for instance), the code already incorporated several important regulations (for instance compulsory registration for citizens and pestilence reporting system),[5] which paved the way for the more completeTaihō Code.[2]
