Japanese Indigenous Religion – Deasy Corporation

Names: No unified name in antiquity. Sometimes called koshintō (“old Shinto”) by later scholars.
Scope: Prehistoric and early historic (Jōmon, Yayoi, Kofun, early Yamato) spiritual systems of the Japanese archipelago.
Nature: Animistic, polytheistic, localized, rooted in clan cults and nature worship.

Jōmon (14,000–300 BCE): Ritual with clay figurines (dogū), fertility cults, nature veneration.
Yayoi (300 BCE–300 CE): Introduction of rice agriculture; fertility, water, and storm deities central.
Kofun (300–600 CE): Ancestor cults of ruling clans; monumental tombs reflect divine kingship.
Early Yamato (6th–8th c.): Clan kami consolidated into imperial cult, culminating in Kojiki (712) and Nihon Shoki (720).

Archaeology: Dogū figurines, haniwa tomb figures, sacred bronze bells (dōtaku).
Oral myths: Later recorded in Kojiki/Nihon Shoki, though layered with political ideology.
Folklore: Regional kami tales, nature cult survivals.
Sacred sites: Ise and Izumo shrines trace lineages back to pre-codified worship.

Kami (spirits): Spirits in rocks, trees, waterfalls, animals, storms.
Clan deities: Each uji (clan) revered an ancestral kami, sometimes linked to natural phenomena.
Fertility deities: Female earth/water spirits linked to agriculture.
Primordial figures (later codified): Izanagi/Izanami, Amaterasu, Susanoo, Tsukuyomi.
Spirits/ghosts (mono, onryō): Restless dead feared and appeased.

Worldview: No separation between divine and natural; kami inhabit landscape.
Creation: Multiple competing myths — recorded later as Izanagi/Izanami story.
Imperial descent myth: Yamato rulers traced lineage to sun kami (Amaterasu) to centralize rule.
Cosmic balance: Harmony with kami essential for agricultural fertility and peace.

Agricultural rites: First-fruits offerings, planting/harvest rituals.
Nature veneration: Sacrifices at waterfalls, groves, sacred rocks.
Purification (harae): Water, salt, fire used to cleanse impurity.
Offerings: Food, cloth, weapons, jewels.
Chieftain-led rituals: Ruler-priests served as intermediaries with clan kami.

Natural shrines: Sacred groves (himorogi), temporary altars.
Permanent shrines (later): Ise and Izumo shrines descend from these practices.
Objects: Dōtaku bronze bells for agricultural rituals; dogū clay figurines as fertility symbols.
Kofun mounds: Tombs seen as cosmic centers linking rulers to gods.

Clan chiefs (uji no kami): Ritual leaders of their deities.
Female shamans/oracles (miko): Spirit mediums, diviners (e.g., Himiko of Yamatai, 3rd c.).
Court ritualists: Emerging in Yamato period, precursors to later kannushi.
Mediums/ascetics: Guided by visions, dreams.

Jōmon: Burials with goods, possible shamanic afterlife journey.
Yayoi: Tomb offerings, ancestor veneration.
Kofun: Monumental mounds linking rulers to divine realm.
Beliefs: Souls lingered as ancestral kami; restless spirits feared as disruptive.

Continental influence: Chinese and Korean migrants introduced metallurgy, Confucian and Daoist cosmology, Buddhism (6th c.).
Codification: Kojiki and Nihon Shoki turned local clan cults into national mythology.
Syncretism: Buddhism and Daoism absorbed into kami cults (shinbutsu-shūgō).
State religion: Later systematized as “Shintō” distinct from Buddhism.
Survivals: Local folk shrines and miko trance practices echo prehistoric cults.
