The sightings, plainly
What people reported
A retelling, not a citation. What follows is the story as the most widely circulated popular accounts tell it — folklore encyclopedias, translations, and the versions that have travelled furthest. It is synthesized rather than keyed line by line to the dated primary texts, and popular versions drift from what those texts actually say. The cited, source-by-source record begins further down this page, and where the two disagree, the record wins.
In the early 1970s, around Mount Hiba in northern Hiroshima, people started meeting something in the woods.
The descriptions are consistent. About five feet tall. Built like a gorilla. A chocolate-brown face, and a body covered in brown hair. Large glaring eyes. Bristled. It stood on two legs, it looked at people, and it went away.
They called it the Hibagon, and it was in the newspapers.
It has paperwork
That's what separates this from everything else in this collection. The Hibagon arrived in the era of local press and municipal offices, so it has the evidentiary trappings of a modern event.
There's a sighting wave with dates — roughly 1970 to 1974. There are named witnesses. There are footprints: a cast reported by Boy Scouts, described as about 25 centimetres long and 15 wide. There was a municipal response.
Nothing was ever confirmed, and the sightings tailed off by the mid-seventies.
Why it belongs here
Because it isn't a break from the tradition. It is the tradition, restarting with better equipment.
Those same mountains had been producing hairy mountain-people for centuries. The yamauba, the mountain crone who lives alone up there and may feed you or eat you. The yamajijii, her male counterpart. The satori, the mountain being that reads your thoughts. Japan has an old, deep, well-attested category of yamabito — mountain people who are not quite people — and Mount Hiba sits in exactly that landscape.
What changed in 1970 wasn't the mountain. It was the reporting format. The same encounter that would once have been collected by a folklorist as a village belief got written up in a regional newspaper with a date and a witness's occupation.
Cryptids are yokai with cameras. Same phenomenon, different notation.
And the timing is worth a pause. The early 1970s is precisely when rural depopulation in Japan was accelerating hard — young people leaving mountain villages for the cities, hamlets emptying, the woods creeping back over places that had been worked for generations.
A hairy man-shaped thing appearing in the hills at the exact moment the hills started emptying of humans is either a coincidence or it isn't, and I know which way I lean.
It got a job
The postscript is entirely Japanese.
The former town of Saijō leaned into it. The Hibagon became a local mascot — cute, brown, round, on merchandise and signage and eventually a burger — and it exported into pop culture, turning up as monsters in video games with names derived from its own.
Which is the same road the umbrella ghost walked, and the akabeko, and the tanuki who ran a bank. Something frightening turns up, and Japan's most reliable response is not to hunt it or exorcise it but to give it a merchandising line.
Fifty years on, a thing that a handful of people genuinely feared meeting in the woods is a cartoon on a paper cup.

Overview
In the early 1970s, around Mt. Hiba in northern Hiroshima, people began meeting something in the woods: about five feet tall, gorilla-built, "chocolate brown face and... covered with brown hair," big glaring eyes, bristled [wikipedia-hibagon]. The Hibagon is Japan's Bigfoot — a datestamped, newspaper-covered sighting wave (c. 1970–74) with footprint finds ("25 cm long and 15 cm wide," reported by Boy Scouts) [wikipedia-hibagon] — and it belongs in the tradition because it is the tradition: the yamabito/mountain-humanoid tradition rebooting itself in the age of local newspapers.
The reading
The mountains that carried yamauba, yamajijii, and satori tales for centuries produced — the very decade rural depopulation accelerated — a hairy mountain-person with modern evidentiary trappings (prints, sighting reports, municipal response). Cryptids are yokai with cameras. The former Saijō town leaned in; the Hibagon survives as regional mascot and pop-culture export (Dragon Quest's "Hibabango" et al.) [wikipedia-hibagon].
