Start of the Heian Period

In 794, Emperor Kammu formally relocated the imperial capital of Japan to Heian-kyō, marking the beginning of the Heian Period (794–1185). The move followed earlier shifts of the capital and was intended to establish a more stable political center, away from the strong influence of Buddhist institutions in Nara. Heian-kyō, located in present-day Kyoto, was designed using a grid pattern inspired by Chinese capital cities, reflecting the influence of Tang dynasty urban planning and administrative models. The relocation redefined the administrative and cultural landscape of Japan. Heian-kyō became the seat of the imperial court, where aristocratic culture developed over the following centuries. Government institutions continued under the ritsuryō system, though in practice power increasingly shifted toward court nobles and influential families. The new capital also helped strengthen central authority over regional governance. The establishment of Heian-kyō marked the start of a period associated with the development of court culture, literature, and art. Works such as The Tale of Genji by Murasaki Shikibu and The Pillow Book by Sei Shōnagon were produced during this era, reflecting court life in Heian Japan. Heian-kyō remained the imperial capital for over a thousand years, until 1868.
