The Nara period (?, Nara jidai) of the history of Japan covers the years from AD 710 to 794. Empress Genmei established the capital of Heij?-ky? (present-day Nara). Except for a five-year period (740-745), when the capital was briefly moved again, it remained the capital of Japanese civilization until Emperor Kanmu established a new capital, Nagaoka-ky?, in 784, before moving to Heian-ky?, modern Kyoto, a decade later in 794.
Japanese society during this period was predominately agricultural and centered on village life. Most of the villagers followed Shintoism, a religion based on the worship of natural and ancestral spirits named kami.
The capital at Nara was modeled after Chang'an, the capital city of the Tang dynasty. In many other ways, the Japanese upper classes patterned themselves after the Chinese, including adopting the Chinese writing system, Chinese fashion, and a Chinese version of Buddhism.
Concentrated efforts by the imperial court to record its history produced the first works of Japanese literature during the Nara period. Works such as the Kojiki and the Nihon Shoki were political, used to record and therefore justify and establish the supremacy of the rule of the emperors within Japan.
With the spread of written language, the writing of Japanese poetry, known in Japanese as waka, began. The largest and longest-surviving collection of Japanese poetry, the Man'y?sh?, was compiled from poems mostly composed between 600 and 759 CE. This, and other Nara texts, used Chinese characters to express the sounds of Japanese, known as man'y?gana.
Before the Taih? Code was established, the capital was customarily moved after the death of an emperor because of the ancient belief that a place of death was polluted. Reforms and bureaucratization of government led to the establishment of a permanent imperial capital at Heij?-ky?, or Nara, in AD 710. The capital was moved shortly (for reasons described later in this section) to Kuni-ky? (present-day Kizugawa) in 740-744, to Naniwa-ky? (present-day Osaka) in 744-745, to Shigarakinomiya (?, present-day Shigaraki) in 745, and moved back to Nara in 745. Nara was Japan's first truly urban center. It soon had a population of 200,000 (representing nearly 7% of the country's population) and some 10,000 people worked in government jobs.
Economic and administrative activity increased during the Nara period. Roads linked Nara to provincial capitals, and taxes were collected more efficiently and routinely. Coins were minted, if not widely used. Outside the Nara area, however, there was little commercial activity, and in the provinces the old Sh?toku land reform systems declined. By the mid-eighth century, sh?en (landed estates), one of the most important economic institutions in prehistoric Japan, began to rise as a result of the search for a more manageable form of landholding. Local administration gradually became more self-sufficient, while the breakdown of the old land distribution system and the rise of taxes led to the loss or abandonment of land by many people who became the "wave people" (fur?sha). Some of these formerly "public people" were privately employed by large landholders, and "public lands" increasingly reverted to the sh?en.
Factional fighting at the imperial court continued throughout the Nara period. Imperial family members, leading court families, such as the Fujiwara, and Buddhist priests all contended for influence. Earlier during this period, Prince Nagaya seized power at the court after the death of Fujiwara no Fuhito. Fuhito was succeeded by four sons, Muchimaro, Umakai, Fusasaki, and Maro. They put Emperor Sh?mu, the prince by Fuhito's daughter, on the throne. In 729, they arrested Nagaya and regained control. However, as a major outbreak of smallpox spread from Ky?sh? in 735, all four brothers died two years later, resulting in temporary reduction in the Fujiwara dominance. In 740, a member of the Fujiwara clan, Hirotsugu, launched a rebellion from his base in Fukuoka, Kyushu. Although defeated, it is without doubt that the Emperor was heavily shocked about these events, and he moved the palace three times in only five years from 740, until he eventually returned to Nara. In the late Nara period, financial burdens on the state increased, and the court began dismissing nonessential officials. In 792 universal conscription was abandoned, and district heads were allowed to establish private militia forces for local police work. Decentralization of authority became the rule despite the reforms of the Nara period. Eventually, to return control to imperial hands, the capital was moved in 784 to Nagaoka-ky? and in 794 to Heian-ky? (literally Capital of Peace and Tranquility), about twenty-six kilometers north of Nara. By the late eleventh century, the city was popularly called Kyoto (capital city), the name it has had ever since.
Some of Japan's literary monuments were written during the Nara period, including the Kojiki and Nihon Shoki, the first national histories, compiled in 712 and 720 respectively; the Man'y?sh?, an anthology of poems; and the Kaif?s?, an anthology written in Chinese by Japanese emperors and princes.
Another major cultural development of the era was the permanent establishment of Buddhism. Buddhism was introduced by Baekje in the sixth century but had a mixed reception until the Nara period, when it was heartily embraced by Emperor Sh?mu. Sh?mu and his Fujiwara consort were fervent Buddhists and actively promoted the spread of Buddhism, making it the "guardian of the state" and a way of strengthening Japanese institutions.
During Sh?mu's reign, the T?dai-ji (literally Eastern Great Temple) was built. Within it was placed the Great Buddha Daibutsu: a 16-metre-high, gilt-bronze statue. This Buddha was identified with the Sun Goddess, and a gradual syncretism of Buddhism and Shinto ensued. Sh?mu declared himself the "Servant of the Three Treasures" of Buddhism: the Buddha, the law or teachings of Buddhism, and the Buddhist community.
Although these efforts stopped short of making Buddhism the state religion, Nara Buddhism heightened the status of the imperial family. Buddhist influence at court increased under the two reigns of Sh?mu's daughter. As Empress K?ken (r. 749-758) she brought many Buddhist priests into court. K?ken abdicated in 758 on the advice of her cousin, Fujiwara no Nakamaro. When the retired empress came to favor a Buddhist faith healer named D?ky?, Nakamaro rose up in arms in 764 but was quickly crushed. K?ken charged the ruling emperor with colluding with Nakamaro and had him deposed. K?ken reascended the throne as Empress Sh?toku (r. 764-770).
The empress commissioned the printing of 1 million prayer charms -- the Hyakumant? Darani -- many examples of which survive. The small scrolls, dating from 770, are among the earliest printed works in the world. Sh?toku had the charms printed to placate the Buddhist clergy. She may even have wanted to make D?ky? emperor, but she died before she could act. Her actions shocked Nara society and led to the exclusion of women from imperial succession and the removal of Buddhist priests from positions of political authority.
Many of the Japanese artworks and imported treasures from other countries during the era of Emperors Sh?mu and Sh?toku are archived in Sh?s?-in of T?dai-ji temple. They are called Sh?s?in treasures and illustrate the cosmopolitan culture known as Tempy? culture. Imported treasures show cultural influences of Silk Road areas, including China, Korea, India, and the Islamic Empire. Shosoin stores more than 10,000 paper documents so-called Sh?s?in documents (). These are records written in the reverse side of the sutra or in the wrapping of imported items that survived as a result of reusing wasted official documents. Sh?s?in documents contribute greatly to the research of Japanese political and social systems of the Nara period, while they even indicate the development of Japanese writing systems (such as katakana).
The first authentically Japanese gardens were built in the city Nara at the end of the eighth century. Shorelines and stone settings were naturalistic, different from the heavier, earlier continental mode of constructing pond edges. Two such gardens have been found at excavations; both were used for poetry-writing festivities.
The Nara court aggressively imported Chinese knowledge about civilization (Tang Dynasty) by sending diplomatic envoys known as kent?shi to the Tang court every twenty years. Many Japanese students, both lay and Buddhist priests, studied in Chang'an and Luoyang. One student named Abe no Nakamaro passed the Chinese civil examination to be appointed to governmental posts in China. He served as Governor-General in Annam or Chinese Vietnam from 761 through 767. Many students who returned from China, such as Kibi no Makibi, were promoted to high government posts.
Tang China never sent official envoys to Japan, for Japanese kings, or emperors as they styled themselves, did not seek investiture from the Chinese emperor. A local Chinese government in Lower Yangzi Valley sent a mission to Japan to return Japanese envoys who entered China through Balhae. The Chinese local mission could not return home due to the An Lushan Rebellion and remained in Japan.
The Hayato people () in Southern Kyushu frequently resisted rule by the Yamato dynasty during the Nara period. They are believed to be of Austronesian origin and had a unique culture that was different from the Japanese people. However, they were eventually subjugated by the Ritsury?.
Relations with the Korean kingdom of Silla were initially peaceful, with regular diplomatic exchanges. However, the rise of Balhae north of Silla destabilized Japan-Silla relations. Balhae sent its first mission in 728 to Nara, which welcomed them as the successor state to Goguryeo, with which Japan had been allied until Silla unified the Three Kingdoms of Korea.
