01 / CONTEXT

Why it happened

The court had already built a continental-style capital at Fujiwara-kyo and completed the Taiho legal code. A larger administrative centre was needed for government offices, court ceremony, aristocratic residences and the growing flow of taxes and goods from the provinces.

02 / EVENT

What happened

In 710, the capital moved north to Heijo-kyo in the Nara basin. Its gridded plan and broad Suzaku Avenue drew on knowledge of Tang capital design, while its actual layout adapted to local terrain and the needs of the Japanese court.

03 / AFTERMATH

What came next

Heijo-kyo remained the principal capital until 784, although Emperor Shomu moved the court several times between 740 and 745. The city became the setting for official chronicles, state temples, international exchange and struggles over land, office and succession.

04 / SIGNIFICANCE

Why it still matters

The move was more than a change of royal residence. It created an administrative landscape that linked the palace to provinces and made the ambitions—and heavy demands—of the ancient state easier to see.
