Heijō-kyō (平城京; also Heizei-kyō, sometimes Nara no miyako) was the Capital of Japan during most of the Nara period, from 710 to 740 and again from 745 to 784. The imperial palace is a listed UNESCO World Heritage together with other places in the city of Nara (cf. Historic Monuments of Ancient Nara).

Empress Genmei ordered the Imperial capital moved from Fujiwara-kyō to Heijō-kyō in 708, and the move to Heijō-kyō was complete in 710. Heijō-kyō was modeled after Chang'an, the capital of Tang-dynasty China, although Heijō-kyō lacked walls. In the city, merchants and traders from China, Korea and India introduced various foreign cultures to Heijō-kyō through the Silk Road. As a result, Heijō-kyō flourished as Japan's first international and political capital, with a peak population of between 50,000 and 100,000.[1] The overall form of the city was an irregular rectangle, and the area of the city was more than 25 km2.
