Shinto: A History
Helen Hardacre's 2017 monograph is the definitive current English-language history of Shinto from ancient origins to the present. Hardacre is Reischauer Institute Professor of Japanese Religions and Society at Harvard; the book is published by Oxford University Press and represents the field's current consensus on Shinto's origins, development, and the fraught question of whether 'Shinto' names a coherent entity before the Meiji period. The book is essential for the origins question because it carefully disentangles: (a) archaeological evidence for kami-related ritual practice in the Yayoi (300 BCE – 300 CE) and Kofun (300–710 CE) periods; (b) the 8th-century textual systematization in the Kojiki (712 CE) and Nihon Shoki (720 CE), both court-commissioned political documents; and (c) the modern scholarly and nationalist retroactive construction of 'Shinto' as a unified ancient tradition.
Hardacre argues that 'Shinto' as a named, self-conscious tradition is largely a Meiji-era (1868–1912) construction; before that, kami worship was continuous with Buddhism and not distinguished from it for most of its history.
The earliest textual attestation of kami worship is the Kojiki (712 CE) and Nihon Shoki (720 CE), both commissioned by Emperor Tenmu (r. 672–686 CE) as political projects — the Kojiki to fix oral traditions legitimating the Yamato dynasty, the Nihon Shoki to present Japan to a Chinese-literate East Asian audience. Composition dates differ from attestation dates: the myths recorded claim cosmogonic antiquity but were set down a millennium after the Yayoi period.
Archaeological evidence at Munakata Taisha (Okinoshima island) establishes ritual deposits of bronze mirrors, iron weapons, and ceremonial objects from the latter half of the 4th century CE through the early Heian period (10th century CE) — the clearest early dated material evidence for kami-site ritual.
Ōmiwa Shrine (Mount Miwa, Nara) is identified in Japanese scholarship as the oldest continuously active shrine; the ritual object deposits there (small bronze mirrors) overlap with and match those at Munakata, suggesting a coordinated ritual network during the Kofun Yamato state-formation period (4th–5th c. CE).
Pre-Kofun evidence (Yayoi period) for kami worship is inferential: burial practices, ritual vessels, and shamanistic assemblages suggest nature-power veneration and agricultural fertility rites, but the kami concept is not directly attested in material record before Kofun deposits.
Hardacre is the leading Western Shinto scholar; the book is widely cited and peer-reviewed. Her anti-essentialist view (Shinto as modern construction) is the mainstream scholarly position but has critics among Japanese scholars who defend the tradition's antiquity as a distinct entity. The gap between Yayoi archaeological inference and 8th-century textual attestation (~1000 years) is a genuine evidential lacuna, not a scholarly invention — Hardacre is honest about this. The Kojiki/Nihon Shoki as political documents complicates their use as religious history; Hardacre's reading of them as state-building texts rather than religious records is well-argued.
