Bōnenkai: The Japanese Year-End Party at Work and With Friends

A bōnenkai (忘年会), literally a forget-the-year gathering, is a year-end party held in December with coworkers, clubs or friends to look back on the year and thank each other. At work it usually means a dinner with drinks, a few short speeches and a closing; the phrases you need are kotoshi mo osewa ni narimashita and yoi otoshi o.

What you need to know

From late November, Japanese restaurants advertise bōnenkai courses, office calendars fill up and trains on Friday nights get noisy. You may be invited to several: one by your company or team, one by a club or class, and one by friends. They share the year-end mood but differ a lot in formality. This guide explains what happens at a work bōnenkai, how it differs from a casual one with friends, the greetings that belong to December, how the formal closing clap works, what the bingo and prizes are about, and how to say no politely when you cannot or would rather not go. It does not repeat the New Year party, shinnenkai, which comes in January. As with any custom, practice differs between companies, regions and generations; many workplaces have made these parties smaller and more optional in recent years.

Bōnenkai are held in December to close the year and thank each other

Work parties are semi-formal; parties with friends are just a fun dinner

Kotoshi mo osewa ni narimashita and yoi otoshi o are the key greetings

Declining with a short reason and thanks is accepted in most workplaces

The year-end party in four cards

The word bōnenkai is written with 忘 (forget), 年 (year) and 会 (gathering). The idea is to put the troubles of the year behind you and thank the people who helped you. Four expressions carry most of the evening.

At work or with friends: two different evenings

The same word covers very different events. A company or department bōnenkai has a structure and senior people; a bōnenkai with friends or a hobby group is simply a December dinner with a toast to the year.

JapaneseRomajiMeaning
今年の忘年会、行く?Kotoshi no bōnenkai, iku?Friend: Are you going to this year's bōnenkai? (casual)
部署の忘年会があります。Busho no bōnenkai ga arimasu.My department has a year-end party.
会費は当日集めます。Kaihi wa tōjitsu atsumemasu.Organiser: We'll collect the fee on the day.
AspectWork bōnenkaiBōnenkai with friends
OrganiserA colleague acting as kanji, often a younger memberWhoever suggests it
PlaceA restaurant, izakaya or hotel banquet roomAn izakaya, a home or a hot pot restaurant
LanguagePolite with seniors, relaxed with peersCasual
ProgrammeOpening words, toast, sometimes games, closingToast and free conversation
PaymentFixed fee per person, sometimes subsidisedSplit the bill

At large companies, the party may include a speech by the head of the department about the year, and sometimes a short performance by new employees. Many workplaces have dropped performances, and nobody should pressure you to do one. If you are asked and do not want to, a smiling refusal is fine.

December greetings and when to use them

Year-end greetings follow the calendar. In December you thank people for the year and ask for their goodwill next year. When you part from someone for the last time before the New Year, you wish them a good one. From 1 January the greetings switch to the New Year set.

JapaneseRomajiMeaning
今年も一年、お世話になりました。Kotoshi mo ichinen, osewa ni narimashita.Thank you for your help all year. (polite)
来年もよろしくお願いします。Rainen mo yoroshiku onegai shimasu.I look forward to working with you next year.
よいお年をお迎えください。Yoi otoshi o omukae kudasai.Have a happy New Year. (formal, when parting)
今年もありがとう。Kotoshi mo arigatō.Thanks for this year too. (casual)
また来年!Mata rainen!See you next year! (casual)

Mini dialogue: the end of a team bōnenkai

Here is a typical exchange as the party breaks up and people go to thank their manager before leaving.

JapaneseRomajiMeaning
部長、今年も一年ありがとうございました。Buchō, kotoshi mo ichinen arigatō gozaimashita.You: Thank you for this year, sir.
こちらこそ。よく頑張ってくれたね。Kochira koso. Yoku ganbatte kureta ne.Manager: Thank you too. You worked hard.
来年もよろしくお願いいたします。Rainen mo yoroshiku onegai itashimasu.You: I look forward to working with you next year.
二次会は行く?Nijikai wa iku?Manager: Are you coming to the second party?
今日はここで失礼します。よいお年を。Kyō wa koko de shitsurei shimasu. Yoi otoshi o.You: I'll leave here tonight. Have a good New Year.
気をつけて。よいお年を。Ki o tsukete. Yoi otoshi o.Manager: Take care. Happy New Year.

Note that buchō, department head, is used as a form of address on its own. Many workplaces address managers by their title, sometimes with the surname: Tanaka buchō.

The closing: shime and the rhythmic clap

Formal parties end with a closing word, shime no aisatsu, by a senior person or the organiser. Some groups then do a tejime, a closing hand clap, to finish together. The leader says o te o haishaku, may I borrow your hands, everyone raises their hands, and on the call they clap in a set rhythm.

The most common pattern, ippon jime, is three claps, three claps, three claps and one clap. Sanbon jime repeats that pattern three times. In parts of the Kantō region some groups use a single clap, which is also sometimes called ippon jime, so watch the leader. After the clap everyone applauds and the party is over.

A senior manager stands at the end of a banquet table and leads a closing clap while the team raises their hands, ready to clap together.
May I borrow your hands: the closing clap that ends a formal year-end party.
JapaneseRomajiMeaning
お手を拝借。O te o haishaku.May I borrow your hands. (leader)
一本締めで締めたいと思います。Ippon jime de shimetai to omoimasu.Let's close with one round of clapping.
よーお!Yōo!Ready! (call before the clap)
ありがとうございました。Arigatō gozaimashita.Thank you. (everyone, after the clap)

Bingo, prizes and the second party

Larger work bōnenkai often include a bingo game or a lottery, with prizes, keihin, bought by the organiser or donated by managers. Winners usually say a word of thanks into the microphone. You do not need to make a speech; a short thanks and a joke about what you will use the prize for is perfect.

After the first party, some people go on to a nijikai at another bar or karaoke. It is optional. If you want to go home, say so with a smile and the year-end farewell. Pay attention to the last train, because December nights get late.

JapaneseRomajiMeaning
ビンゴ!Bingo!Bingo!
景品keihinprize
ありがとうございます。大事に使います。Arigatō gozaimasu. Daiji ni tsukaimasu.Thank you. I'll take good care of it.
二次会はカラオケだって。Nijikai wa karaoke datte.They say the second party is karaoke.

Declining politely

Not everyone wants to spend a December evening at a work party, and in most workplaces declining is accepted, especially with a little notice. Thank the organiser for the invitation, give a short reason without detail, and add the year-end greeting. You do not need to explain family plans or health. In recent years some people talk openly about skipping year-end parties, and many companies keep them optional; still, read your team.

JapaneseRomajiMeaning
お誘いありがとうございます。Osasoi arigatō gozaimasu.Thank you for inviting me.
あいにく、その日は都合が悪くて。Ainiku, sono hi wa tsugō ga warukute.Unfortunately that day doesn't work for me.
今回は欠席させていただきます。Konkai wa kesseki sasete itadakimasu.I'll have to miss this one. (humble)
皆さんによろしくお伝えください。Minasan ni yoroshiku otsutae kudasai.Please give everyone my regards.

Common mistakes

  • Saying yoi otoshi o at the start of the party. It is a parting phrase for the last meeting of the year.
  • Saying akemashite omedetō in December. That greeting starts on 1 January.
  • Drinking too much because it is the end of the year. Work parties are still work relationships.
  • Ignoring the organiser's fee or deadline. Reply to the invitation by the date given and bring the right amount if it is cash.
  • Leaving without a word to your manager. A ten-second thank-you at the end matters more than staying late.

Get the December greetings right

Year-end greetings are a small set with strict timing, which suits a quick quiz. Ask Mocchi: quiz me on Japanese year-end and New Year greetings, and tell me when each one is used. Mocchi checks your answers, explains the timing and keeps track of the ones you mix up.

If you want to try the bōnenkai conversation out loud, AI Sensei can play your manager at the end of the party with Sakura-sensei: thank the Sensei for the year, decline the second party and say yoi otoshi o.

Key points

A practical way to improve

December gives you a set of greetings you can only use for a few weeks, so practise them now. Say kotoshi mo ichinen osewa ni narimashita and rainen mo yoroshiku onegai shimasu aloud, then the casual versions for friends. Practise the closing call, o te o haishaku, and the rhythm of the clap. Then write two replies to a bōnenkai invitation, one accepting and one declining, and say them to yourself in a polite, warm tone. Mocchi, Unihongo's study assistant, can check your decline message with /correct and tell you if it sounds too blunt for your manager.

FAQ

Frequently asked questions

When are bōnenkai held?

Bōnenkai are held in December, most often from early to mid December and before offices close for the New Year holidays. Some groups hold them in late November. Restaurants get busy, so organisers often book weeks ahead.

What is the difference between bōnenkai and shinnenkai?

A bōnenkai is held at the end of the year to look back and thank each other. A shinnenkai is held in January to welcome the new year and share goals. Some workplaces hold both; others hold only one.

Do I have to go to my company's bōnenkai?

In most companies it is voluntary, and a short polite reason is enough to decline. In some teams it is seen as an important social event, so if you can, join for at least the first part. If attendance is said to be required, it is reasonable to ask HR how it is treated.

When do you say yoi otoshi o?

Say yoi otoshi o, or the fuller yoi otoshi o omukae kudasai, when you part from someone for the last time before the New Year, for example at the end of the bōnenkai or on the last working day. Do not use it on 1 January; then you say akemashite omedetō gozaimasu.
