How did the Heian form of government contribute to the cultural flowering of Japan in this period?

As described in Chapter 7, during the seventh and eighth centuries the Japanese ruling house pursued a vigorous policy of adopting useful ideas, techniques, and policies from the more advanced civilization of China. The rulers built a splendid capital along Chinese lines in Nara and fostered the growth of Buddhism. Monasteries grew so powerful in Nara, however, that in less than a century the court decided to move away from them and encourage other sects of Buddhism.

The new capital was built about twenty-five miles away at Heian (HAY-ahn; modern Kyoto). Like Nara, Heian was modeled on the Tang capital of Chang’an (although neither of the Japanese capitals had walls, a major feature of Chinese cities). For the first century at Heian the government continued to follow Chinese models, but it turned away from them with the decline of the Tang Dynasty in the late ninth century. The last official embassy to China made the trip in 894. During the Heian period (794–1185), Japan witnessed a literary and cultural flowering under the rule of the Fujiwara family.
