Okuri-inu: The Dog That Follows You Home Through the Mountains

Okuri-inu is a Japanese folk tradition about a dog that follows travellers on night mountain paths, recorded in Edo-period books and early-Showa folklore collections under several regional names.

You are walking a mountain path after dark, and somewhere behind you an animal is keeping pace — not closing in, not dropping back, just following. In the older Japanese tellings of this encounter, the walk itself is survivable; what is dangerous is the moment you stumble. Fall, the stories say, and the animal is on you at once; stay upright — or convince it that you are still upright — and it will simply see you as far as your door.

Quick facts

  • Verdict: folklore, not an internet story. The motif appears in Edo-period printed books and in folklore collections published in the early Showa era, long before anonymous message boards existed, and no trace of an online origin turned up for this file.
  • Name: okuri-inu (送り犬), with the regional variants okuri-okami and okuri-itachi.
  • Type: a yokai tradition recorded across Japan. Shogakukan’s Digital Daijisen Plus, as collected on Kotobank, defines it as a wild dog that follows people along mountain paths at night.
  • Earliest confirmed record: a mention in the Edo-period materia medica work Honcho Shokkan, drafted by Hitomi Hitsudai and published by his son around 1697 — though under the regional name okuri-okami rather than okuri-inu.
  • Where it spread: across the country, with the name shifting by region — okuri-inu from Tohoku to Kyushu, okuri-okami from Kanto through Kinki and in Kochi Prefecture, and okuri-itachi on the Izu Peninsula and in Toda, Saitama Prefecture.

What the story says

The basic situation is the same everywhere it is told. A person is walking a mountain road at night, and an animal — a dog, sometimes called a mountain dog or a wolf — falls in behind them and follows closely, step for step, without attacking. English Wikipedia’s account of the tradition sets out what happens next. If the walker trips and goes down, the animal is on them immediately, and the encounter ends badly. If they fall but behave as though nothing has happened — as though they meant to crouch, as though they never lost their footing at all — the animal holds back and the escort continues. The safe ending comes at the door of the house: the traveller turns and speaks a parting word, or sets out something as thanks, and the follower leaves.

The regional variants carry their own details. The okuri-okami, the wolf-shaped version of the follower, is said to dislike the smell of a burning fire-rope and to flee from it. In Koumi, in Minamisaku District, Nagano Prefecture, local tradition sorted mountain dogs into two kinds: the okuri-inu, which protects the person it walks behind, and the mukae-inu, which attacks. So the creature is not fixed on one side of the line between guardian and threat; which one you have met depends on where the story is being told, and on what you do when your foot slips.

Earliest confirmed record

The oldest mention traced for this file is in Honcho Shokkan, a work of materia medica. Kotobank’s dictionary entries describe it as a manuscript left by Hitomi Hitsudai, written around 1692, and brought into print by his son Gankō in 1697 as a twelve-volume, ten-book edition — while another dictionary collected on the same site gives 1695 and a twelve-volume, twelve-book edition instead, so the exact publication year is not settled between reference works. Japanese Wikipedia reports that this book contains the statement that a person who does not fight back against the okuri-okami, and who pleads for their life, will be protected from the beasts of the mountains.

Three caveats belong with that date, and they belong only here. First, the passage is about the okuri-okami — the regional wolf name — and not about the okuri-inu as such. Second, the original Edo-period text was not consulted for this article; the content is taken from Japanese Wikipedia’s summary of it. Third, an earliest confirmed record is not the same as a first appearance: nothing here rules out an older mention that this survey did not reach.

What is documented

What can be pinned to printed sources is mostly the shape of the tradition rather than any event.

A second Edo-period record exists. Wakan Sansai Zue, the 105-volume illustrated encyclopaedia written by the Osaka physician Terajima Ryoan in 1712 and issued by the Osaka publisher Kyōrindō, is reported by Japanese Wikipedia to describe the okuri-okami leaping over the head of a night traveller again and again. A person who is not frightened and does not fight back comes to no harm; a person who is frightened into falling is bitten. The fall, in other words, is already the pivot of the story two centuries before folklorists went out to collect it.

The regional spread of the names is documented in both the Japanese and English encyclopaedia entries, and the dog-or-wolf split is confirmed independently by Digital Daijisen Plus. The Koumi division into protective okuri-inu and hostile mukae-inu is recorded by Japanese Wikipedia.

There is also one concrete anecdote in the record. Chiisagata-gun Mindanshu, a folklore collection published in the early Showa period, preserves a story from Shioda in Nagano Prefecture about a woman who gave birth in the mountains and encountered an okuri-inu. Japanese Wikipedia’s entry additionally cites modern reference literature on yokai, including a yokai dictionary edited by Murakami Kenji (Mainichi Shimbunsha, 2000) and a volume by Tada Katsumi on the inhabitants of imaginary worlds (Shinkigensha, 1990).

What is contested

The main unsettled points are bibliographic rather than supernatural. The authorship of Chiisagata-gun Mindanshu could not be fixed for this file: the attribution that surfaced during research was not verified against the original volume, so no name is asserted here.

Beyond that, the tradition resists being flattened into one creature. A single article can make okuri-inu, okuri-okami and okuri-itachi look like three names for one thing, but the recorded behaviour differs: the Honcho Shokkan passage presents an animal that protects a traveller who submits, the Wakan Sansai Zue passage presents one that vaults over the traveller’s head and bites only those who fall in fear, and the Koumi tradition puts the protective and the dangerous animal into separate categories altogether. The consistent thread is not the animal but the rule of the encounter — composure at the moment of the stumble decides how the night ends.

One last thing worth saying plainly: the pretend-you-did-not-fall rule is a piece of folk narrative, told about a creature of legend. It is not advice about meeting a real wild animal, and nothing in the sources presents it that way.

Claim Evidence Sources
Shogakukan's Digital Daijisen Plus defines okuri-inu as a nationwide yokai tradition about a wild dog that follows people along mountain paths at night, and notes that in some regions the follower is a wolf and the name becomes okuri-okami. Documented [3]
The name of the tradition varies by region: okuri-inu from Tohoku to Kyushu, okuri-okami from Kanto through Kinki and in Kochi Prefecture, and okuri-itachi on the Izu Peninsula and in Toda, Saitama Prefecture. Documented [1] [2] [3]
English Wikipedia records the core plot elements: the animal follows a walker closely on a night mountain path, a person who falls is attacked at once but one who acts as though they have not fallen is spared, and offering words of parting or a gift of thanks on reaching home sends the animal away. Documented [1]
Japanese Wikipedia reports that the Edo-period materia medica work Honcho Shokkan, drafted by Hitomi Hitsudai and published by his son, states that a person who does not fight back and pleads for their life will be protected from beasts in the mountains; Japanese dictionaries collected on Kotobank give the publication as around 1697 but also record a differing date of 1695. Contested [2] [4]
The 1712 illustrated encyclopaedia Wakan Sansai Zue, written by the Osaka physician Terajima Ryoan, describes the okuri-okami leaping repeatedly over the head of a night traveller, harming those who fall in fear but leaving unafraid walkers alone. Documented [2] [5]
In Koumi, Minamisaku District, Nagano Prefecture, mountain dogs were divided in local tradition into the okuri-inu, which protects people, and the mukae-inu, which attacks them. Documented [2]
An early-Showa folklore collection, Chiisagata-gun Mindanshu, records an anecdote about a woman from Shioda in Nagano Prefecture who encountered an okuri-inu after giving birth in the mountains; the collection's authorship could not be confirmed against the original for this file. Contested [1] [2]
The earliest record traced here is a mention under the regional name okuri-okami rather than okuri-inu, and it comes from Japanese Wikipedia's summary rather than the original Edo-period text, so an older record cannot be ruled out. Contested [2]
