Heijō-kyō was a very important city in Japan. It served as the national capital for a long time. It was the capital during most of the Nara period. This lasted from the year 710 to 740. The city became the capital again from 745 to 784. 
The city had a very specific shape and design. It was shaped like an irregular rectangle. The total area of the city was more than 25 square kilometers. 
History tells us how the city began. Empress Genmei was the leader who ordered the move. She wanted to move the capital from Fujiwara-kyō. She gave this order in the year 708. The move to the new city was finished in 710. 
Many interesting facts exist about the city's size and people. At its peak, the population was between 50,000 and 100,000 people. The Suzaku-ōji road was built to look spectacular. It was wide enough for foreign guests to pass through. In the Sanjō area, the road was about 85 meters wide.

Heijō-kyō was a major city that served as the capital of Japan. It was the political center during most of the Nara period. The city functioned as the capital from 710 to 740. It later served as the capital again from 745 to 784. 
The city was designed with a specific layout inspired by foreign models. It was modeled after Chang'an, which was the capital of the Tang dynasty in China. While the designers followed the Chinese style, Heijō-kyō lacked defensive walls. The city took the form of an irregular rectangle. This urban area covered a total space of more than 25 square kilometers. 
A central feature of the city was a massive north-south avenue called Suzaku-ōji. This street served as the main artery for the city's layout. It stretched 3.7 kilometers from the Rajōmon Gate in the south to the Suzakumon Gate. The Suzakumon Gate was the main entrance to the palace complex. The road was built to be spectacular. Its size was intended to accommodate the passage of foreign envoys. 
Archaeologists have learned much about the road through careful excavation. Since 1974, researchers have clarified the exact route of the Suzaku-ōji. They found that the width was about 74 meters between the centers of the east and west gutters. In the Sanjō area, the distance between the embankments reached about 85 meters. Excavations even revealed a previous road that was only 23 meters wide. In 2010, workers restored a section of the road near the Suzakumon Gate. This restored area measured 70 meters wide and 210 meters long.
The history of the city began with a major political decision. Empress Genmei ordered the imperial capital to move from Fujiwara-kyō. She issued this order in 708. The massive move to Heijō-kyō was completed in 710. 
Heijō-kyō was a diverse and crowded place. At its peak, the population was between 50,000 and 100,000 people. The city was connected to the wider world via the Silk Road. Merchants and traders traveled from China, Korea, and India to reach the capital. These travelers introduced various foreign cultures to the people living in Heijō-kyō. This constant flow of people made the city a flourishing center of activity and new ideas.
Religious architecture was also a vital part of the city's landscape. Many ancient Buddhist temples were located within the Heijō-kyō area. Some of these sites are now recognized as UNESCO World Heritage Sites. Notable temples include Tōdai-ji, Yakushi-ji, Kōfuku-ji, and Gangō-ji. Other significant sites include Daian-ji and Saidai-ji. These structures show the religious importance of the capital during the Nara period.
In 2010, Japan celebrated the 1,300th anniversary of the establishment of Heijō-kyō. Various commemorative events were held throughout the Nara Prefecture. These celebrations ran from April 24 to November 7. The events included special displays of national treasures and cultural properties. People also participated in walking events to explore famous historical places. These celebrations helped people connect with the long history of the ancient capital.
