Heijo Palace Ruins

Historical Background: The Capital That Shaped a Nation

In 710, Empress Genmei moved Japan's capital from Fujiwara-kyō to a newly planned city in the Nara Basin. This new capital, Heijō-kyō, was modeled in part on Chang'an, the cosmopolitan Tang Chinese capital, and was laid out in a vast grid stretching roughly 4.8 kilometers east to west and 4.3 kilometers north to south. At its northern center stood Heijō Palace, an enclosed precinct of approximately 1 by 1.3 kilometers ringed by an earthen wall.

Within those walls were the great audience halls used for imperial enthronements, the residential quarters of the emperor and empress, the offices of the central bureaucracy, and elegant banquet gardens. From this place, the early ritsuryō state issued laws, compiled official histories such as the Kojiki and Nihon Shoki, welcomed envoys from Tang China and the Korean kingdoms, and oversaw the great Buddhist projects—including the casting of the colossal Buddha at Tōdai-ji—that defined the Nara period.

The capital's life here was not unbroken. In 740, Emperor Shōmu briefly relocated the court to Kuni-kyō, and the original First Daigokuden (Great Audience Hall) was dismantled and rebuilt there as the Kondō of the provincial temple of Yamashiro Province. When the court eventually returned to Heijō, a Second Daigokuden was erected on a slightly different site. In 784, the capital was moved again—to Nagaoka-kyō and ultimately to Heian-kyō (modern Kyoto)—and the great palace was abandoned, its halls dismantled and the site gradually reclaimed by farmland.

Why Heijō Palace Site Earned Its Designations

That this immense imperial precinct survived at all is something of a miracle. After the court left, the area was returned to rice cultivation, which—paradoxically—helped protect the buried postholes, foundation stones, drainage channels, and discarded wooden tablets (mokkan) that lay beneath the surface. By the early twentieth century, scholar-activists such as Tanada Kajūrō campaigned tirelessly to prevent development on the site, and in 1952 the precinct was designated a Special Historic Site, the highest classification under Japan's cultural property system.

Systematic excavation by the Nara National Research Institute for Cultural Properties began in earnest in the 1960s and has continued ever since, yielding tens of thousands of artifacts and producing a uniquely detailed picture of an early Japanese imperial city. The site's outstanding universal value was further recognized in 1998, when it was inscribed on the UNESCO World Heritage List as one of the eight component assets of "Historic Monuments of Ancient Nara." The designation reflects not only the site's archaeological importance but also its role as physical evidence of the formation of the Japanese state and its early cultural exchange with continental Asia.

Architectural Highlights: A Reconstructed Capital

Spread across the vast park are several major reconstructions, each based on decades of archaeological research, comparison with surviving early temples such as Hōryū-ji and Yakushi-ji, and study of contemporary continental architecture. Each structure was designed to convey the dignity and scale of the original while meeting modern requirements for safety and accessibility.

Visitor Information and Highlights

The palace site is freely accessible, and admission to the major reconstructed buildings and museums is free of charge. The park is divided into two main zones. The southern zone centers on Suzakumon Plaza (Suzakumon Hiroba), the main visitor gateway, where five complex facilities offer orientation exhibits, dining, souvenir shopping, and a full-scale reconstruction of an envoy ship of the kind that carried Japanese missions to Tang China. The northern zone contains the First Daigokuden and its associated reconstructed gates and pavilions, the Heijō Palace Site Museum operated by the Nara National Research Institute, and the Excavated Site Exhibition Hall, where archaeological remains are preserved in situ beneath protective shelters.

For those without a car, the most convenient way to circulate is the "Gurutto Bus," a low-fare loop service connecting Kintetsu Yamato-Saidaiji Station, JR Nara Station, Kintetsu Nara Station, and various stops within the park. The site is also enjoyable on foot or by bicycle, especially in spring when roughly 1,000 cherry trees bloom around the Second Daigokuden site, and in autumn when the wide expanses of silver-plumed susuki and ogi grass catch the late afternoon light.

Surrounding Attractions

The Heijō Palace Site sits within easy reach of several other components of the Historic Monuments of Ancient Nara World Heritage cluster. To the southwest, the great temples of Yakushi-ji and Tōshōdai-ji preserve some of Japan's most important early Buddhist sculpture and architecture, including authentic Nara-period structures. To the east lie Tōdai-ji, home to the colossal bronze Great Buddha; Kōfuku-ji, with its iconic five-story pagoda; Kasuga Taisha, the great Fujiwara family shrine; and the deer-filled expanse of Nara Park. Saidai-ji, the western counterpart to Tōdai-ji and another major Nara-period foundation, lies just one stop west of the palace site by Kintetsu Line. Together they offer the chance to combine the political and ceremonial heart of the ancient capital with the religious institutions that defined its spiritual life.
