If there’s one social ritual that will define your life as an expat in Japan, it’s the nomikai (飲み会) — the after-work drinking party that sits somewhere between team-building exercise and unwritten job requirement. I’ve watched so many foreigners walk into their first nomikai completely unprepared, make a few innocent but memorable mistakes, and spend the next week wondering why the office atmosphere felt slightly off. Japanese drinking culture runs deeper than most people expect, and getting it right — or at least not getting it spectacularly wrong — can genuinely shape your relationships here.
This guide is for people who are staying. Not tourists looking for a fun night in Shinjuku, but expats who want to build real connections and understand what’s actually happening at the table.
What Is Nomikai and Why Does It Matter So Much?
The word nomikai literally means “drinking gathering,” but that translation undersells it by about 80%. In Japanese workplace culture, nomikai functions as a social equalizer. Hierarchies that feel rigid during business hours loosen significantly once the first round of beer arrives. According to a 2023 survey by Recruit Holdings, roughly 60% of Japanese office workers say nomikai helps improve team communication — and that number reflects something real that I’ve personally seen play out.
When I first started working with expat-focused startups in Tokyo, I noticed that the foreigners who integrated fastest into their Japanese teams were almost always the ones who showed up to nomikai consistently, even if they drank slowly or not at all. Attendance signals commitment. Leaving early — without a genuinely good excuse — signals something else.
Nomikai typically happen at izakaya (居酒屋), casual Japanese pubs that serve food alongside drinks. Popular chains like Torikizoku and Watami are affordable and common venues, with most group dinners operating on a nomihōdai (飲み放題) system — an all-you-can-drink package usually priced between ¥1,500 and ¥2,500 per person for a 90 to 120-minute window.
Key Drinking Etiquette You Need to Know
This is where things get specific, and where I’ll ask you to actually memorize a few things.
Never Pour Your Own Drink
In Japanese drinking culture, you pour for others and others pour for you. Pouring your own drink — especially at a formal nomikai — signals that you’re either unaware of the custom or indifferent to it. Watch your neighbors’ glasses and refill them when they’re getting low. Someone will do the same for you.
The Kanpai Moment
The kanpai (乾杯) — the toast — marks the official start of the meal. Nobody drinks before it. The most senior person at the table typically leads, and everyone raises their glass. One common mistake: raising your glass higher than your boss’s. In Japan, the junior person holds their glass slightly lower as a gesture of respect. It’s a small thing, but people notice.
Drinking and Not Drinking Are Both Fine — But Communicate
Japan has grown significantly more accommodating toward non-drinkers, especially as of 2026, when alcohol-free options on nomihōdai menus have become genuinely standard. Sparkling water, non-alcoholic beer, and soft drink sets are widely available. If you don’t drink, just tell your colleagues early and simply — “I don’t drink alcohol, but I’d love to join” (「お酒は飲めないのですが、ぜひ参加させてください」) works perfectly. The participation matters more than the drink in your hand.
The Two-Stage Night: Nijikai
Don’t be surprised when someone announces nijikai (二次会) — the “second party” — after the first venue wraps up. This is usually a smaller, more relaxed group heading to a bar or karaoke. Nijikai is actually where deeper conversations happen. If you want to get closer to your Japanese colleagues, this is often the better opportunity.
Reading the Room: Unwritten Rules Expats Miss
Japanese social settings rely heavily on kuuki wo yomu (空気を読む) — literally “reading the air,” meaning picking up on unspoken social cues. In a drinking context, this shows up in subtle ways.
If someone’s glass is full but they haven’t been drinking, don’t keep offering to top it up — they may be pacing themselves or signaling they’re done. If the mood gets quiet after the bill is split, that’s usually the cue to wrap up, not order another round. I’ve seen well-meaning expats misread these signals and accidentally extend evenings by 45 minutes that the group was mentally done with.
Also, the bill at nomikai is almost always split equally (warikan, 割り勘) regardless of what you ordered. Don’t try to calculate your exact share — it’s considered a little uncomfortable and slows things down.
What Foreigners Often Get Wrong
The most common mistake I’ve seen — and I’ve watched this happen more than once at company events — is treating nomikai as an opportunity to get very drunk. In Western drinking culture, a free-flowing open bar is sometimes an invitation. In Japan, it is not. Getting visibly drunk before your colleagues, speaking loudly, or becoming emotionally expressive puts everyone in an uncomfortable position. People won’t say anything directly to you, but it will be remembered.
The second mistake is leaving without a proper farewell. In Japan, aisatsu (挨拶), or proper greetings and goodbyes, matter. If you need to leave early, quietly tell your direct manager or the event organizer in advance, thank the host sincerely, and say goodbye to people individually if the group is small. Slipping out silently — what Westerners sometimes call an “Irish exit” — lands poorly here.
FAQ
Q: Do I have to drink alcohol at a Japanese work nomikai?
No. Non-alcoholic options are now standard at most venues, and Japanese colleagues generally respect a politely stated preference. What matters is that you show up and engage.
Q: How do I decline a drink that’s already been poured for me?
Place your hand lightly over your glass and say 「結構です」(kekkou desu) — “I’m fine, thank you.” A small smile helps. It’s recognized and respected.
Q: How much should I budget for a typical nomikai in Tokyo?
With nomihōdai included and food shared, expect to pay between ¥3,000 and ¥5,000 per person at a mid-range izakaya. Higher-end settings can push toward ¥8,000 or more.

Conclusion: Show Up, Pay Attention, and Enjoy It
Honestly, once you understand the framework, nomikai becomes one of the most genuinely enjoyable parts of expat life in Japan. The food is good, the atmosphere is warm, and the conversations you have after a couple of rounds of beer with a Japanese colleague can move years faster than anything that happens in a conference room.
My personal advice: go to the first few nomikai you’re invited to, even if you’re tired. Watch how others handle the pour, the kanpai, the nijikai invitation. Ask questions. Japanese people are far more forgiving of honest effort than of apparent indifference.
