The afterlife, plainly
Who comes to collect you
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.
The dead don't find their own way to court. Somebody comes for you.
Two somebodies, actually, and they are a matched pair. Gozu has the head of an ox on a man's body. Mezu has the head of a horse. They carry iron implements, they are enormous, and their job is to take custody of your soul and present it before the courts of hell.
They also run messages for the king of hell between times, which is a nice bureaucratic touch. Escort service and courier department, same two staff.
They're immigrants
Gozu and Mezu are Chinese — Ox-Head and Horse-Face of the Chinese underworld — and they arrived in Japan with the imported machinery of Buddhist hell.
If you know Journey to the West, you've met them. They're the pair the Monkey King beats up when he storms the underworld to strike his name out of the register of the dead, which is a fairly typical day for them. They tend to lose.
In Japan they naturalized fast and turn up in the serious classics — in the great twelfth-century tale collection, and in the Tale of the Heike.
The origin story worth keeping
There's a legend about where Gozu came from, and it's genuinely lovely.
An ox worked its entire life. Hauled, ploughed, pulled, carried — the full span of a working animal's existence, which in premodern agriculture is not a small thing — and then it died.
And the king of hell, seeing that, took pity on it and made it one of his faithful servants.
Not a punishment. A promotion.
There's a pattern in this tradition of animals keeping their working identity into the next world. The ox that laboured is given a post where it goes on working, but now with standing, and with a superior who noticed. As afterlives for a draught animal go, that's about as good as anything on offer.
The whole department
Once you have Gozu and Mezu, you can draw the org chart, and Japanese hell genuinely supports one:
Intake — an old woman on the riverbank who takes the clothes off the newly dead, and her colleague who hangs them on a tree to weigh how deep you sank on the crossing.
Transport and enforcement — Gozu and Mezu, bringing you in.
The bench — Enma, the judge, and above him a fuller system of Ten Kings, each hearing your case at a set interval after death. That's why Japanese memorial services fall on the days they do: the seventh day, the forty-ninth, the anniversaries. Those are court dates.
General labour — the oni, carrying out sentences.
And then, operating outside all of it, the kasha: a burning cart that arrives at funerals to snatch particularly wicked corpses before the proper authorities can process them. An unauthorized competitor, intercepting the department's freight.
The whole thing is an institution with departments, escorts, paperwork, scheduled hearings, and at least one problem with theft in transit. Japan received an afterlife and immediately gave it an administration.

Overview
The dead don't walk themselves to court. Hell's escort service is a matched pair: Gozu — an ox's head on a man's body — and Mezu — a horse's — the psychopomps who "captur[e] souls of the deceased and present[] them before hell's courts," running messages for the king of hell besides [wikipedia-gozumezu]. Chinese imports (Ox-Head and Horse-Face of the Chinese underworld, roughed up by Sun Wukong in Journey to the West), naturalized into Japanese classics: they appear in the Konjaku Monogatarishū and the Heike [wikipedia-gozumezu].
The tender origin (worth keeping)
One legend: an ox who labored its whole life died, and the king of hell, in pity, "made him one of his faithful servants" [wikipedia-gozumezu] — hell's enforcer as a beast of burden promoted. The tradition's beasts keep their day jobs even in the afterlife.
The staff roster, complete enough
Enma (bench) → Datsue-ba and Ken'e-ō (riverbank intake) → Gozu and Mezu (transport and enforcement) → the oni warders (general labor) → the kasha (unauthorized competitor, stealing corpses en route). The hell-bureaucracy page can be assembled now — org chart included, because the material genuinely is one.
