Yōrō Code

700's Japanese legal code of the Nara period

The Yōrō Code (養老律令) was one iteration of several codes or governing rules compiled in early Nara period in Classical Japan. It was compiled in 718, the second year of the Yōrō regnal era by Fujiwara no Fuhito et al., but not promulgated until 757 under the regime of Fujiwara no Nakamaro under Empress Kōken. and differences may have been limited. Still, when Nakamaro put the laws into effect in 757, it was unpopular among the nobility as it "slowed down the promotion schedule for officials."

While the precursor code (Taihō Code) does not survive, a substantial amount of Yōrō Code is preserved in the exegetical piece, Ryō no gige (『[[:ja:令義解) (833), especially the civil codes. In English language scholarly literature, some commentators merely state that the code is preserved in a fragmentary state, but other academics do note preservation is nearly complete for the civil code portion. The Ryō no gige contains the full text of the ryō (or civil/administrative code part) except for two chapters according to a Kadokawa publishing house history dictionary, the missing portions being the warehouse statute (倉庫令) and the medical service statute (医疾令), and even this lacuna can be partly be filled from a collections of fragments of the codes. Other sources agree, adding that for the civil code, almost all of the text that runs to Article 955 has been restored. Relying on the Tang dynasty penal code that survives, a complete reconstruction of the Yōrō penal code has also been undertaken.

The ritsuryō codes were modeled after the civil and penal codes of the Tang dynasty, in particular, the code of the era passed in 651 which was then current is named by scholars as the basis of the two ritsuryō codes.

The Code remained in effect until the early 10th century, after which it became an obsolete dead letter law code, but not formally repealed and hence valid at least "in paper" until the Meiji Restoration. During the feudal age in Japan, various ministerial offices were awarded to as formality to samurai (e. g., Ishida Mitsunari as jibu no shō; Furuta Oribe, Ii kamon no kami, Sakai uta no kami etc.) without any responsibilities or authorities vested in the office under the code.
