What Japan's Public Napping Culture Gets Right About Mornings America Gets Wrong

Japan’s inemuri — the practice of dozing openly in meetings, on trains, and at one’s desk — works because tiredness is treated as a shared, visible fact rather than a private failure. American morning culture does the opposite: it treats every yawn as evidence against you, something to suppress until you’re alone. That single difference in what a society does with the evidence of exhaustion, more than any difference in biology, may explain why “just wake up earlier” lands so differently across cultures.

None of that means Japanese people sleep more, sleep better, or that inemuri is some secret productivity hack waiting to be imported wholesale. The narrower and, I think, more useful claim is this: watch what happens to morning willpower advice once the surrounding culture stops requiring anyone to perform an alertness they don’t actually have.

What Is Inemuri, Actually?

The scholar most associated with serious study of inemuri is Brigitte Steger, a sleep researcher at the University of Cambridge, whose ethnographic work — including her book-length study Sleeping in Public in Japan — treats the practice as a social institution rather than a medical curiosity. Steger’s framing, as I understand it from her published work, is that inemuri (roughly “sleeping while present”) is not simply napping. It’s dozing that happens while still notionally participating: head bowed but body upright in a train seat, eyes closed for a stretch during a long meeting, a few minutes gone at a desk between tasks.

Her research pushes back on the easy Western reading of this as laziness or disrespect. In many of the settings she studied, a manager who nods off in a meeting isn’t seen as checked out — he’s read as someone who has worked himself past the point of staying upright, which functions as a kind of credential. The visible exhaustion becomes proof of the invisible effort. Steger has also been careful, in her writing, to note that inemuri is context-dependent: acceptable for a senior employee in a meeting he’s already contributed to, less acceptable for a junior one, and not remotely universal across every Japanese workplace or generation. It’s a tolerance with edges, not a blanket cultural permission.

I want to be direct about where I’m departing from her: Steger’s scholarship is descriptive and historical — it explains what inemuri is, where it came from (she traces some of its logic back through older ideas about presence and diligence), and how it functions inside specific Japanese social contexts. What follows is my own extension of that material into a comparative claim about morning routines generally, and it should be read as a synthesis I’m building, not an argument Steger herself makes.

A Framework: Hidden Tiredness Versus Witnessed Tiredness

The distinction doing the real work, once you sit with the inemuri material long enough, is this.

Some cultures treat a lapse in alertness — nodding off, running late, needing five more minutes of sleep — as an individual moral failure, something to be hidden, apologized for, or overcome through visible effort. Call this the hidden-tiredness model. Other cultures, or at least other institutional settings, treat exhaustion as an externally visible, socially processed fact: something everyone can see, comment on, and account for, with no requirement that the tired person perform a version of themselves they aren’t currently able to be. Call this the witnessed-tiredness model.

Inemuri sits close to the witnessed end of that spectrum. Part of what makes it tolerable — again, within limits, and unevenly across contexts — is precisely that it’s public. A colleague dozing three seats down on the Yamanote Line at 7:40am is legible to everyone in the car. There’s no illusion to maintain, because nobody was asked to maintain one. The tiredness has already been socially processed; it doesn’t need to be confessed, because it was never hidden in the first place.

American morning culture, by contrast, runs almost entirely on the hidden-tiredness model, and it does this even when the tiredness is common knowledge. A remote worker who is exhausted logs in anyway and types “good morning!” in Slack with an exclamation point doing a lot of quiet labor. A parent running on four hours of sleep still shows up to the 9am stand-up with a coffee as a prop rather than a plea. The tiredness is often just as visible, in practice, as it is in a Tokyo commuter car — everyone half-suspects everyone else is running on fumes — but the social contract requires a performance of alertness anyway. Nobody is officially allowed to be seen as tired, so everyone spends energy hiding it that could otherwise go toward recovering from it.

This is worth pausing on, because it’s the part that generalizes past Japan and past sleep specifically: a norm that criminalizes the visible signal of a problem doesn’t make the problem rarer, it just makes the signal disappear while the underlying condition persists, often for longer, because nobody with the power to intervene can see it happening.

Why “Just Wake Up Earlier” Assumes a Culture, Not Just a Body

Most morning-routine advice is delivered as if it were addressed to a body in a vacuum: set your alarm, don’t hit snooze, get sunlight, and willpower will do the rest. What the inemuri comparison suggests is that this advice is also, quietly, addressed to a culture — one where tiredness is shameful enough that the only acceptable strategy is to eliminate every visible trace of it through sheer discipline before anyone else clocks it.

That’s a lot of what’s going on in the genre of writing about disciplined early risers. A closer look at several famous morning schedules finds that the discipline being celebrated is usually less about the early hour itself and more about a rigid, privately maintained structure nobody else was allowed to see falter — Kant’s fixed 5am walk, Darwin’s carefully guarded work blocks, all performed with nobody watching the seams. The 5am wake-up genre isn’t really instructing people in sleep physiology. It’s instructing them in a specific moral posture: handle your own exhaustion, alone, before the world can catch you in it.

Inemuri offers a genuine counter-model, not because Japan has solved sleep deprivation (it hasn’t — Japan’s government has recognized karoshi, death from overwork, as a distinct medical and legal category since the late 1980s, which is its own argument that visibility alone doesn’t fix an unsustainable schedule) but because it demonstrates that a society can decide tiredness doesn’t have to be hidden to be acceptable. The exhaustion is still there. What’s different is who’s allowed to know about it, and what it costs to let them.

A Self-Contained Answer: Does This Mean Public Napping Is “Better” Than Willpower?

Not exactly, and it’s worth answering this cleanly on its own, because it’s the most likely follow-up question. Inemuri doesn’t reduce how tired Japanese workers are — by most measures, including cross-national sleep-duration data, Japan remains among the more sleep-deprived developed nations. What inemuri changes is the cost of being seen as tired. In a hidden-tiredness culture, a person pays twice: once in lost sleep, and again in the effort spent concealing the effects of that lost sleep from coworkers, friends, or family. In a witnessed-tiredness culture, that second cost is largely removed, even though the first one remains. So the honest claim isn’t “Japan does mornings better.” It’s that Japan has, in this one narrow respect, stopped charging people for something willpower alone can’t actually fix — the visible symptom — and that this narrower fix is more achievable than the wholesale discipline that hidden-tiredness cultures keep prescribing instead.

The Aviation Comparison

The clearest analogy I’ve found for this outside of sleep culture entirely is commercial aviation crew-rest policy. Pilots and flight crews operate under fatigue-reporting systems where declaring yourself too tired to fly is not just tolerated but procedurally required — an institutional structure that makes exhaustion visible on purpose, because hidden fatigue in a cockpit is catastrophic in a way that hidden fatigue in an office merely feels catastrophic. Nobody expects a pilot to white-knuckle a transatlantic flight through sheer discipline; the entire system is built on the premise that tiredness has to surface, get logged, and get acted on by someone other than the tired person alone.

Most white-collar mornings have no equivalent structure. There’s no fatigue report, no colleague whose job is to notice you’re cooked and adjust the plan. The inemuri-tolerant train car and the fatigue-reporting cockpit both function, oddly, as forms of institutional witness — places where somebody else’s awareness of your state does the fixing work that pure self-discipline was never actually built to do. An ordinary weekday morning, for most people, has neither institution nor culture doing that noticing. It just has an alarm clock and an unspoken expectation that you’ll have handled everything privately by the time anyone else is looking.

Where This Framework Gets Shaky

I want to flag the limits of this comparison honestly, because it would be easy to overstate. First, inemuri is not a monolith — Steger’s own fieldwork describes plenty of situations where dozing off is read badly, particularly for younger or lower-status employees, which means “Japan tolerates visible tiredness” is true only within a fairly specific set of hierarchical and situational conditions, not as a blanket national trait. Second, I’m extending a scholarly description of one cultural practice into a general theory about willpower and shame that Steger doesn’t make herself; the leap from “inemuri is publicly tolerated in Japanese offices” to “witnessed tiredness generally beats hidden tiredness as a strategy” is mine, and it deserves more testing than one blog post can give it. Third, a culture’s broader mix of sleep norms — longitude effects, labor policy, latitude, and light exposure all shape sleep timing independently of any of this — matters at least as much as the moral-visibility question, and a wider survey of global sleep differences will surface plenty of variation this two-category framework simply can’t explain, since most countries land somewhere between the hidden and witnessed poles rather than cleanly at either one.

What I’m more confident about is the narrower claim: a lot of morning-routine advice assumes, without saying so, that tiredness must be hidden and defeated privately, and that assumption is a cultural inheritance, not a biological law. Inemuri is useful less as a technique to copy than as proof that the assumption isn’t universal — that somewhere, a fair amount of exhaustion just gets to sit there, in public, unhidden, without anyone requiring it to first be defeated.

What a Witnessed Approach to Mornings Might Actually Look Like

If hidden tiredness is expensive because it has to be concealed, and witnessed tiredness is cheaper because concealment isn’t required, the practical question is what “witnessed” could mean for someone who isn’t a Tokyo commuter or an airline pilot. It doesn’t have to mean napping at your desk. It could mean something as small as a housemate who knows, without being told, that you had a bad night and doesn’t need you to perform otherwise at breakfast. Or a friend who has seen you oversleep before and reacts with a shrug rather than a lecture, which — paradoxically — tends to make people more honest about their mornings, not less accountable for them. The common thread isn’t surveillance or shame; it’s the removal of the requirement to fake a state you’re not in, replaced by the much lighter social cost of simply being seen as you actually are.

None of this resolves the underlying sleep debt, in Japan or anywhere else. Inemuri doesn’t add hours to anyone’s night. But it does suggest that the exhausting part of a bad morning is often not the tiredness itself — it’s the performance layered on top of it, built for an audience that, in a different culture, might not have required the performance at all.

There’s a smaller, stranger version of this same trade-off in how people already handle physical illness versus tiredness. A cough is allowed to be visible; nobody expects a person hacking through a meeting to have hidden it successfully beforehand. A late night, though, is treated as something closer to a confession than a symptom — worthy of concealment precisely because it’s assumed to be within a person’s control in a way a cough isn’t. Inemuri quietly rejects that assumption. It treats a slumped head on a train the way most cultures already treat a cough: as something that happened to a person, not something a person failed to prevent. Once tiredness gets sorted into the “happened to you” category instead of the “you let this happen” category, the whole question of hiding it starts to look beside the point.
