It is 7:04 p.m. at an izakaya two minutes from the office. Red lanterns, fluorescent light, a menu nobody has opened yet.
Your boss says four words — "toriaezu, biiru de" — and six people who each wanted something different nod and close the menu. Nobody voted. Somehow everyone agreed.
Two hours later your own beer has gone flat, because you have spent the evening filling everyone else's glass. A junior colleague you have exchanged maybe nine words with keeps appearing at your elbow with a fresh bottle the second yours drops below half. You reach for it yourself, just once, to top up your own glass. A hand gets there half a second before yours does, and quietly takes the bottle out of the equation.
Start with the toast, because it is the one part visitors already understand. 乾杯 (kanpai) is written with the characters for "dry" and "cup" — empty the glass, together, on the count. It looks like the whole ritual. It is actually the smallest part of it. The real mechanism is not what is being drunk. It is who is allowed to pour it, and for whom.
The rule runs on rank. A junior employee fills the glass of anyone senior first, always with two hands if they are receiving, and never lets a superior's cup sit empty for long. Pouring for yourself has an actual name — 手酌 (tejaku) — and it is not neutral. At a table where everyone is supposed to be watching everyone else, reaching for your own bottle quietly announces that nobody has been. It is less a breach of etiquette than a small, public piece of evidence that the group failed at its one job that night.
That job has a name too: 飲みニケーション (nomunication), a post-war blend of nomu — to drink — and communication, coined for the exact arrangement that built modern corporate Japan. The office runs vertically all day: titles, seating charts, whoever speaks first in a meeting. The izakaya is where that hierarchy is allowed to tilt sideways for a few hours, and alcohol is the permission slip. Things get said there — a disagreement with the boss, an admission of a mistake, a request nobody would risk sober — that the org chart makes impossible everywhere else.
Even the opening order is doing work. "Toriaezu biiru" — beer, for now — is less a drink order than a synchronisation signal. Six different preferences would mean six different arrival times, six different toasts, and a night that never quite starts. One shared order means one shared kanpai, on cue, and the actual negotiating over highballs and oolong tea gets pushed to round two, once the group has already, formally, begun.
None of this is technically compulsory anymore, and that matters. Japan's revised power-harassment law, in force for every employer since 2022, means a manager who pressures a subordinate into attending, or criticises them for not pouring, is now taking on real legal exposure — not just an awkward conversation. A 2023 Persol Research Institute survey found close to 80% of workers already consider that kind of pressure harassment outright. And the parties themselves are visibly shrinking: Tokyo Shoko Research found 59.6% of companies still held a bōnenkai, the formal year-end version, in 2024, down from 78.4% in 2019 — a drop no single pandemic year fully explains.
The assumption, everywhere, is that this is dying because young Japan hates it and is finally being allowed to say so. A 2024 Nippon Life survey found the opposite generational split: 68.8% of workers in their twenties said they want to attend their company's year-end party, compared with 51.9% of those in their forties and just 40.3% in their fifties. The youngest people in the building are the ones keeping the tradition alive. It is the exhausted middle, not the newcomers, who want out — because a first-year employee, new to the company and often new to the city, has almost no other room where a senior person will sit across from them for three hours and actually talk. The ritual that looks like an obligation from the outside is, for the person with the least access to power, one of the only doors left open.
- "Toriaezu biiru" ("beer, for now") is such a fixed opening move that some izakaya print it as its own menu line, priced separately from every other beer on the list.
- Self-pouring has its own word — 手酌 (tejaku) — precisely because it is common enough to need naming, and mildly awkward enough that naming it works as a gentle warning.
- Since 2022, Japan's power-harassment law covers every employer regardless of size, meaning pressuring staff over a nomikai is no longer just bad manners — it is something a company can be formally reported for.
