Oyagami

The concept of oyagami arises from lineage-based ancestor worship in Japan: original ancestors (sorei) of an uji (clan) became objects of cultic veneration as ancestral or clan deities. Over historical time those clan gods (uji no kami) in many cases shifted from strictly kin-based foci to land- or locality-linked guardian deities (ujigami), reflecting social changes in which lineage identity and local community overlapped. In some modern or sectarian developments the parental metaphor was extended cosmologically so that an oyagami is conceived as the ultimate source of life or productivity for the world; Tenrikyo explicitly uses Oyagami as the personal name/title of the single creator deity, translated as "God the Parent."

Sources do not provide a consistent physical description or fixed iconography for oyagami; the term denotes a role or status (ancestor/parent-deity) rather than a single embodied form. Ritual and institutional loci for ancestral veneration (for example household or family altars and mausoleums such as mitamaya) serve as material foci for worship of ancestral spirits including those called oyagami, and sectarian usages (Tenrikyo) address the deity by title rather than by standardized anthropomorphic imagery.

Described functions of oyagami in the cited materials are primarily relational and cosmological rather than catalogues of discrete supernatural acts. Oyagami may be (1) an ancestral spirit worshipped as the founding ancestor of a clan (sorei/ujigami), (2) a tutelary presence that "cares for human beings in the same way that human parents care for their children," and (3) in some sectarian thought the primal source of vitality and productive power for the cosmos, the giver of life from whom humans are described as "offspring of the kami." The sources do not attribute hostile capacities (possession, sickness-causing) or specific ritualized modes of interaction to oyagami in the provided material.
