Nomikai (飲み会, work drinking parties) in Japan are not optional social events — they are semi-mandatory workplace obligations that affect your team relationships and career perception. You don’t have to drink alcohol, but attendance — especially in your first 6–12 months — matters enormously. Key rules: arrive on time, pour drinks for seniors before yourself, wait for the kanpai (toast) before drinking, and stay through at least the first venue. Missing nomikai repeatedly signals social withdrawal.
“Everyone going for drinks tonight — 7pm, Shinjuku izakaya.”
This message in a Japanese workplace group chat is not quite an invitation. It’s closer to an announcement of something you’re expected to attend. There’s no “Sorry can’t make it!” culture built into the response options.
Nomikai (飲み会) — literally “drinking gatherings” — are the engine of Japanese workplace relationships. Understanding how they work, how to behave in them, and when (and how) you can decline is one of the highest-value cultural skills for any foreigner working in Japan.
What Is a Nomikai?
A work drinking party, typically held at an izakaya. They happen:
- After major project completions
- Welcome parties (歓迎会, kangeikai) for new employees
- Farewell parties (送別会, soubetsukai) when someone leaves
- Year-end parties (忘年会, bonenkai) — December, almost mandatory
- Cherry blossom viewing (お花見, hanami) — Spring
- Irregular “let’s go for drinks” (飲みに行こう) — anytime
The frequency varies wildly by company culture. Some teams go monthly. Some go twice a year. International companies tend toward less frequent nomikai. Traditional Japanese companies may have them every few weeks.
Why It Matters
Japan’s workplace culture has a sharp boundary between formal (tatemae) and informal (honne) behavior. Official meetings are formal and guarded. Nomikai is where real relationships form — where people say what they actually think, where juniors can speak more freely with seniors, and where social trust is built.
Foreigners who consistently skip nomikai often report:
- Being excluded from informal information loops
- Being perceived as standoffish or uninterested in the team
- Slower career advancement in Japanese companies
None of this is explicitly stated. It accumulates silently.
Nomikai Rules and Etiquette
Pouring Drinks
Never fill your own glass first. Pour for the person next to you — especially seniors. When your glass is empty, someone will notice and fill it (or you can hint by slightly raising it). If someone refills yours, hold the glass slightly.
The First Toast (乾杯 / Kanpai)
Everyone stands. The most senior person leads. You say “乾杯！” and clink glasses. Drink immediately. Do not start eating or drinking before kanpai.
Seating
The seat farthest from the entrance (kamiza, 上座) is for the most senior person. As a junior or newcomer, you’ll be directed toward the entrance-side seats — don’t fight it.
Drink Order
You’re not required to order alcohol. Soft drinks, oolong tea (ウーロン茶), and non-alcoholic cocktails (mocktails) are increasingly normal — especially post-COVID. No explanation needed. Just order what you want.
Food
Nomikai usually includes shared plates ordered for the table, often on a nominomi/tabehoudai (all-you-can-drink or eat/drink plan). Let seniors order first. Take smaller portions initially — more can be ordered.
Pace and Staying
A standard nomikai runs 2 hours. After that comes nijikai (二次会, the second venue) — a smaller, more informal continuation. Nijikai is optional; the main event is not.
How to Decline When You Need To
Declining occasionally is acceptable — declining every time signals something is wrong. When you do need to miss:
Acceptable reasons:
- Prior family commitment (hardest to argue with)
- Work deadline you’ve already told your manager about
- Health issue
How to phrase it:
“申し訳ないんですが、今夜は先約がありまして…”
(Moushiwake nai n desu ga, konya wa sakiyaku ga arimashite…)
“I’m terribly sorry, but I have a prior commitment tonight…”
The ellipsis (…) is intentional in Japanese — it leaves the reason vague, which is socially smoother than over-explaining.
What not to say:
- “I don’t feel like drinking” — implies you’re declining because of the drinking, not the timing
- “I have plans with friends” — fine once in a while, but used too often implies you’re prioritizing personal life over team
If You Don’t Drink Alcohol
Japan is much more accepting of non-drinkers than it was 10–15 years ago. Post-COVID, the culture has shifted significantly. What works:
- Order soft drinks without comment — most people won’t ask
- If asked, “アルコールが体に合わなくて” (Alcohol doesn’t agree with my body) — this is understood and respected
- Participate fully in the toasts — just hold your soft drink and say kanpai with everyone
- Stay as long as others, eat the food, engage in conversation — the point is togetherness, not alcohol consumption
After Nomikai: Missing the Last Train
Nomikai often runs close to or past the last train (typically midnight). Options:
- Taxi — expensive after midnight (¥3,000–8,000 depending on distance)
- Manga/internet café (ネットカフェ) — overnight option, ¥1,500–3,000, surprisingly comfortable
- All-night karaoke — another option until trains resume at 5–5:30am
- Plan ahead: check last train times before you go
