Chinjusha
In Japan, a chinjusha (鎮守社•鎮社; or tutelary shrine) is a Shinto shrine which enshrines a tutelary kami (鎮守神, chinjugami); that is, a patron spirit that protects a given area, village, building or a Buddhist temple. The Imperial Palace has its own tutelary shrine dedicated to the 21 guardian gods of Ise Shrine.
