Kasuga Taisha was established at the same time as the capital and is dedicated to the deity responsible for the protection of the city. Kasuga Taisha was also the tutelary shrine of the Fujiwara, Japan's most powerful family clan during most of the Nara and Heian Periods. Like the Ise Shrines, Kasuga Taisha had been periodically rebuilt every 20 years for many centuries. In the case of Kasuga Taisha, however, the custom was discontinued at the end of the Edo Period.

Kasuga Taisha is famous for its lanterns, which have been donated by worshipers. Hundreds of bronze lanterns can be found hanging from the buildings, while as many stone lanterns line its approaches. The lanterns are lit twice a year on the occasion of the Lantern Festivals in early February and mid August.
