Traditions: Kojiki; Nihon Shoki / Nihongi
Motif: Purification after contact with death and the emergence of deities
Connection verdict: Related court-compiled Japanese myth cycles with visible variants, not two independent inventions
Confidence: High for shared mythic cycle; limited for claims about an original pre-chronicle version
The scene and its setting
After the failed journey to the land of the dead, Izanagi performs a cleansing. In the Kojiki, the action is located in a river-mouth setting; discarded objects and stages of washing generate deities. Among the best-known births are Amaterasu from his left eye, Tsukuyomi from his right eye, and Susanoo from his nose. The scene links contact with death, purification, and the ordering of divine roles. It is not a modern hygiene lesson with divine names attached.
The Nihon Shoki—often cited through Aston’s English title Nihongi—also preserves Izanagi/Izanami creation materials and purification-related versions. But the chronicle is notable for its alternative accounts: it does not force every deity birth into a single sequence identical to the Kojiki. Even where recognizable names and events recur, the framing and placement of variants can differ. A claim that “the two chronicles say exactly the same thing” would miss the value of comparing them.
Why the overlap is strong
Both chronicles are early eighth-century court compilations (Kojiki 712; Nihon Shoki 720). They draw on a related Japanese mythic repertoire in which Izanagi, pollution or defilement associated with death, cleansing, and deity origins are intertwined. The shared names and episode structure make common circulation far more persuasive than independent coincidence. Yet “shared repertoire” is a better description than a proven line-by-line copy from one extant chronicle into the other.
There are reasons to be cautious about a simple source tree. The compilers had different literary and political projects. The Nihon Shoki openly places variants alongside its main narrative, and later religious practice cannot automatically be read backward as identical to every ancient textual detail. The earliest written version is not necessarily the earliest version ever told. Conversely, we cannot reconstruct a pristine oral original from two manuscripts simply by deleting what looks editorial.
What the comparison reveals
The purification sequence is a hinge between death and renewed cosmic order. That is more specific than saying “many religions have water cleansing.” A cross-cultural water motif might be interesting, but these two sources warrant comparison because they belong to the same named mythic cycle and emerged from historically adjacent compilation projects. Their differences show that related religious narratives can be curated in multiple authoritative forms.
For present-day readers, respect matters. The chronicles are primary witnesses to an early written mythic tradition, not exhaustive statements of every Japanese religious community’s current Shinto practice. Nor is purification here interchangeable with moral guilt. The texts’ bodily, cosmic, and political dimensions deserve their own interpretation.

Source limit: Both linked English translations are historical and have dated terminology. This report compares their episode-level testimony; it does not claim a complete account of Japanese manuscript history or living Shinto practice.
Open questions
Which differences reflect compiler selection rather than earlier regional variants? How do later shrine and ritual traditions interpret the cleansing differently? Which modern annotated Japanese editions best clarify the sequence of deity births?
