히에이 산
In addition, many of the more important or powerful temples are built in locations which are favorable according to the precepts of Chinese geomancy. For example, Enryaku-ji, which sits atop Mount Hiei to the north-east of Kyoto, is said to defend the city from evil spirits by being placed in that direction. The arrangements of mountains and other geographic features in particular directions around the temple play important roles as well. This custom continued for a long time. Eight centuries after the founding of Enryaku-ji, the Tokugawa shogunate established Kan'ei-ji in a similar direction for the protection of their Edo Castle. Its mountain-name, Mount Tōei (東叡山 "Tōei-zan"), takes a character from Mount Hiei (比叡山 "Hiei-zan"), and can be interpreted as meaning "the Mount Hiei of the East."
