히에이 산
It was named in a reference both to the Enryaku-ji's location atop Mount Hiei ("Tōeizan" means "Mount Hiei of the East"), and also after the era during which it was erected, like Enryaku-ji (named after the Enryaku year period). Because it was one of the two Tokugawa "bodaiji" (funeral temple; the other was Zōjō-ji) and because it was destroyed in the closing days of the war that put an end to the Tokugawa shogunate, it is inextricably linked to the Tokugawa "shōguns".
