The Asuka 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 of Ritsuryō laws in classical Japan.
[1] This also marks the initial appearance of the central administrative body called the Daijō-kan (Council of State) composed of the three ministers—the Daijō-daijin (Chancellor), the Sadaijin (Minister of the Left) and the Udaijin (Minister of the Right).
[2] In 662, Emperor Tenji is said to have compiled the first Japanese legal code known to modern historians.
The Ōmi-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 Kiyomihara ritsu-ryō of 689.
