In Japan, the Azure Dragon is one of the four guardian spirits of cities and is said to protect the city of Kyoto on the east. The west is protected by the White Tiger, the north is protected by the Black Tortoise, and the south is protected by the Vermilion Bird. In Kyoto there are temples dedicated to each of these guardian spirits. The Azure Dragon is represented in the Kiyomizu Temple in eastern Kyoto. Before the entrance of the temple there is a statue of the dragon which is said to drink from the waterfall within the temple complex at nighttime. Therefore each year a ceremony is held to worship the dragon of the east.
