A mitamaya (御霊屋, literally mitama "soul [of the dead]" + ya "house"; also called, otamaya, tamaya, or soreisha 祖霊社, or "Reibyo" 霊廟)[1] is an altar used in Shinto-style ancestor worship, dedicated in the memory of deceased forebears. It generally has a mirror symbolizing the spirits of the deceased or a tablet bearing their names and is used not only to enshrine blood relatives, but also to honor respected non-family members.[2]
Since Buddhist funeral rites dominate in Japanese religious practice, mitamaya are found less often in Japanese houses than their Buddhist counterpart, the butsudan. Their value are also below that of the more highly respected kamidana.[3]
