Inugami, Loyal Dog Spirit

Japan Folklore Spirit Ally Possession Blood Pact

Inugami are dog spirits bound by ritual, serving families as guardians or curses. Fiercely loyal, they can possess the unworthy and retaliate when disrespected.

Story beats

  1. 1) A dog is ritually sacrificed and its spirit tethered to a family line.
  2. 2) Inugami patrol households, warning of danger, biting unseen threats.
  3. 3) Neglect or cruelty turns them vengeful; they possess foes—or careless kin—causing illness and barking fits.
  4. 4) Proper offerings and respect keep the pact mutual; otherwise, the binding frays.

Context & symbolism

Inugami straddle pet devotion and ritual exploitation. They reflect the idea that protection bound by pain can twist. Possession tales caution against mistreating loyal guardians.

They also echo clan identity: families reputed to hold inugami gain fear and respect.
