During this time, the Yamato Court which was established years before rapidly grew. The Asuka Period is also defined by how much the social, political, and artistic aspects of the Japanese community transformed after Buddhism was introduced to the country. It was also during this period that the term used to refer to Japan was changed from Wa to Nihon.

The definitive characteristics of the Heian Period include the peak of Buddhism, Taoism, and Chinese influences. It was also during this time that the Japanese Imperial was at its highest, and became known for its advances in literature and poetry.

However, although there were still emperors during this period, the ones who truly had power over the affairs of Japan were the members of the Fujiwara Clan. The Fujiwara Clan was among the most powerful families of the Japanese aristocracy.
