The gardens and architecture of the Heian period lasted from the late 8th century to the late 12th century. They reflect the process of Japanese reinterpretation and finally assimilation of Chinese culture.
A significant feature of Japanese gardens is their ability to arouse poetic emotions in the viewer and this was especially true of the Heian period.
Rocks, flowers trees are not just inanimate objects but possess their own being and sensitivity. To be sensitive to their sensitivity is a prerequisite of Heian art.
