Period of Japanese history from 794 to 1185

The Heian period is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kammu, moved the capital of Japan to Heian-kyō. Heian (平安) means 'peace' in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court, noted for its art, especially poetry and literature. Two syllabaries unique to Japan, katakana and hiragana, emerged during this time. This gave rise to Japan's famous vernacular literature, with many of its texts written by court ladies who were not as educated in Chinese as their male counterparts.

Heian Japan in Depth

History

The Heian period was preceded by the Nara period and began in 794 CE after the movement of the capital of Japan to Heian-kyō (modern Kyoto), by the 50th emperor, Emperor Kanmu. Kanmu first tried to move the capital to Nagaoka-kyō (modern Kyoto), but a series of disasters befell the city, prompting the emperor to relocate the capital a second time, to Heian. A rebellion occurred in China toward the end of the 9th century, making the political situation unstable. The Japanese missions to Tang China were suspended and the influx of Chinese exports halted, a fact which facilitated the independent growth of Japanese culture called kokufū bunka (国風文化).

Culture

The Heian period saw the rise of two esoteric Buddhist sects, Tendai and Shingon.

Tendai is the Japanese version of the Tiantai school from China, which is based on the Lotus Sutra, one of the most important sutras in Mahayana Buddhism. It was brought to Japan by the monk Saichō. An important element of Tendai doctrine was the suggestion that enlightenment was accessible to "every creature". Saichō also sought independent ordination for Tendai monks. A close relationship developed between the Tendai monastery complex on Mount Hiei and the imperial court in its new capital at the foot of the mountain. As a result, Tendai emphasized great reverence for the emperor and the nation.
