Nara Period

The Nara Period was the era when Nara (Heijo Kyo) was the capital. From 710 (the third year of the Japanese War), the capital was established at Heijo-kyo, to 784 (the third year of the Enretsu period) when the capital was moved to Nagaoka-kyo, totaling 74 years. It was the period of prosperity of the rule-based society, which was reflected in political and economic systems, class relations, culture, and foreign relations.

During the period of Emperor Kohito and Emperor Kanmu, the imperial court tried to rectify the chaotic political situation, reduce fiscal expenditures, reform the military system, expand territory to the northeastern region, and seek to reshape and re-strengthen the legal system. Japan's earliest historical books, "Kojiki" and "Nihon Shoki", were also compiled one after another at this time, thus entering Japan's historical era.
