During the Edo period these shrines reached 500 in number, but after the Meiji Restoration many were abandoned,[8] and others united with shrines in the area. Presently, it is estimated that there are about 130 Tōshō-gū.[9] The National Tōshō-gū Association lists a total of 48 shrines.[10]
Ieyasu was deified with the name Tōshō Daigongen (東照大権現), meaning "Great Gongen, Light of the East"[11] (a gongen is a Buddha who has appeared on Earth in the form of a kami to save sentient beings), and this is what gives Tōshō-gū shrines their name.
