Inugami

The inugami is a dog spirit, made by sorcery, kept by a family and passed down through the generations.

It's western Japan's version of the fox familiar — strongest in Shikoku and Kyushu, which is exactly where fox belief is thin. The trickster and familiar niches get filled by whatever animal the region has. On Shikoku the tanuki takes the trickster role and the inugami takes the familiar one. The folklore partitions like an ecosystem.

How it was said to be made

The tradition describes the creation ritual plainly, and it's ugly.

A dog is starved, and buried up to the neck, with food placed just out of reach. The animal dies in extremity — and the whole point is that its anguish is the material. That concentrated suffering is what gets bound and kept. One account records shrine maidens drying and selling matter from dog remains under the name.

This is what the folklore says, not something anyone should soften. And the cruelty isn't incidental to the belief — it's the mechanism. The spirit's power is made of grievance, and the maker's willingness to inflict it is part of the transaction.

A household with an inugami prospers. It gets things. And if it turns the spirit on someone, that person suffers: chest pain, pain in the limbs, swaying, and — the tell everyone watched for — barking.

The part that isn't folklore

Here is where this entry stops being a monster story, and it needs saying directly.

The stigma never attached to the spirit. It attached to the families.

Inugami-mochi — "inugami-owning" households — were identified, tracked through bloodlines, and avoided. In Shikoku there was a custom of checking a family's bloodline for inugami before a marriage, and the belief was often held to transmit through women, so it was daughters whose prospects it destroyed.

These were real families. In real villages. Named ones, known locally, for generations. People would not marry into them. Their land was worth less. Their children grew up knowing which side of the line they were on, and nothing they did could move them across it — because the accusation is unfalsifiable, and the prosperity that was supposed to prove it is the thing every household is trying to have.

And the same machine ran elsewhere on a different animal. In Izumo it was foxes, and the fox-owning families were treated identically — Lafcadio Hearn documented it in the 1890s, down to the land prices. In the Kantō it ran on a small weasel-ish familiar; in Chūbu on a fox kept in a tube.

Four regions, four animals, one sociology: a hereditary, invisible, inherited taint that decided who your children could marry.

That is the most useful thing this entry has to offer, and it's not supernatural at all. The animal is a local detail. The structure — a community needing a mechanism for deciding which families are outside — is the constant, and it survived into living memory.

The catalogs drew him with dignity

One small counterweight to end on.

Both of the great illustrated catalogs include him. Sekien's plate, from 1776, is not a horror image: a dog-figure in robes, upright, composed, accompanied by a white child-attendant.

He drew the thing at the centre of all this discrimination as a small dignified clergyman, and it's worth looking at, because it's a reminder that the picture and the social reality were never really about the same thing.
