What Is a Bōnenkai (Bonenkai)? A Guide to Japan's Year-End Gatherings
A bōnenkai (bonenkai, literally "forget-the-year party") is a uniquely Japanese end-of-year dinner and social gathering held to leave the past year's troubles behind.
These parties are concentrated in December and serve as a way to draw a line under a busy year, swap stories over food and drink, and reset before the new year begins.
The tradition has deep roots: records of "toshi-wasure" (year-forgetting) gatherings appear as early as the Muromachi period, and the term "bōnenkai" itself is documented from the Edo period through the Meiji era.
Attendees can vary widely.
Bōnenkai are held among coworkers, classmates, hobby groups, and circles of friends.
The atmosphere also varies.
Some are lively and loud, while others are quiet meals enjoyed at a relaxed pace, depending on the people and venue.
When Bōnenkai Are Held and How Much They Cost
Most bōnenkai take place from late November through December, with bookings concentrated in mid- to late December.
Work-related parties are usually held on weekday evenings, while gatherings among friends often fall on weekends, with many parties wrapping up after about two hours.
Recent surveys in Japan show the typical budget falls between 4,500 and 5,000 yen per person, often for a set course meal with all-you-can-drink (nomihōdai) included.
Popular venues include izakaya (Japanese-style pubs) and restaurants, as well as hotel banquet halls and yakatabune (traditional roofed boats).
What to Expect at a Japanese Bōnenkai: The Typical Flow
If it's your first time, knowing what to expect on the day will help you feel at ease.
Details vary, but most bōnenkai follow this general flow.
Arriving and Taking Your Seat
Guests gather at the venue and are shown to their seats.
At work-related parties, seating order matters: senior figures are typically given the seat of honor (kamiza), though gatherings among friends are usually informal.
Arriving 5 to 10 minutes before the start time gives you time to settle in.
Opening Remarks
The host or a representative often gives a short opening speech.
Drinks are then handed out so everyone can begin the party together.
Kanpai (Toast), Food, and Conversation
The party officially begins with a call of "kanpai!" (cheers), after which everyone digs into the food and starts chatting.
In Japan, it's customary for everyone to raise their glass together before taking the first sip.
Closing Remarks
A representative usually gives a few closing words at the end.
At work parties, the gathering may end with a ceremonial hand clap known as ippon-jime (one round of claps) or sanbon-jime (three rounds).
Because clear beginnings and endings are valued, staying until the close helps you experience the full flow.
Bōnenkai Etiquette: Key Manners to Keep in Mind
A bōnenkai is meant to be fun, but consideration for others matters too.
Rather than memorizing complicated rules, focusing on basic courtesy makes it easier to join in.
Wait for the Toast Before Drinking
Even if drinks arrive first, it's customary to wait until the kanpai before taking a sip.
Starting together creates a sense of unity that's central to the experience.
Know How to Receive a Pour
Someone may pour a drink for you during the party.
The custom of pouring for one another is becoming less strict, but a quick word of thanks when someone pours for you leaves a good impression.
Holding your glass with both hands (rather than just one) when receiving a pour is considered polite.
Don't Force Yourself to Drink
Some people don't drink alcohol or prefer not to.
If that's you, simply order a soft drink or non-alcoholic beer from the start, and join in at your own pace.
Mentioning early on that you don't drink makes it easier for others to be considerate.
Notify Early About Late Arrival or Cancellation
Bōnenkai are usually planned with a confirmed headcount in advance.
If you're going to be late or can't attend, let the organizer know as early as possible.
Same-day cancellations may incur charges for the set course meal, so this is worth keeping in mind.
Tips for Easy Conversation at Your First Bōnenkai
Even if you're not confident in your Japanese, a bōnenkai can be a great chance to connect.
Reacting to others' stories tends to flow more naturally than trying to talk at length yourself.
Start with Easy Topics
Good icebreakers include food, travel, seasonal events, and places you've visited in Japan.
Light questions like "Have you been anywhere good recently?" are easy for others to answer.
It's often easier to ease in before asking about someone's job or specialized topics.
Offer a Quick Thank-You or Compliment
"Thank you for inviting me."
"This dish is delicious."
Even short phrases like these make conversation easier to start.
Coming across as warm matters more than perfect phrasing.
Be a Good Listener
In Japanese conversation, listening attentively is often valued as much as speaking.
Nodding and giving short responses (aizuchi) shows you're engaged in the conversation.
Dressing and Acting the Part at a Bōnenkai
What to wear depends on who you're meeting and where.
For work-related parties, lean slightly more polished; for gatherings with friends, casual usually works fine.
That said, dressing very differently from the venue's vibe can feel awkward.
When in doubt, aim for clean, neat clothes appropriate for a meal out.
At izakaya or venues with tatami rooms, you may need to remove your shoes, so easy-to-remove footwear and clean socks are a good choice.
In terms of behavior, try not to talk over others.
Speaking too loudly throughout, or getting noticeably more drunk than everyone else, can dampen the mood.
If you take photos, a quick word to those in the picture is appreciated.
At work-related gatherings, it's often best to keep photo-taking and sharing to a minimum.
Nijikai (After-Party) and Splitting the Bill: Customs to Know
After the main bōnenkai, many groups move on to a "nijikai," or second-round gathering.
These are usually held at bars or karaoke spots, and joining is entirely optional, so feel free to decide based on your energy.
The bill is typically split evenly among everyone, a practice called "warikan."
Since the cost is often set in advance, having a little cash on hand is a good idea.
While more venues now accept cashless payment, you may still need to pay the organizer (kanji, the person coordinating the party) in cash.
What to Do If You're Invited to a Bōnenkai While Traveling
If a Japanese friend or acquaintance invites you to a bōnenkai during your trip, consider joining if it works with your schedule.
It's a chance to experience the rhythm of Japanese social life that you can't get from sightseeing alone.
Before going, it's helpful to confirm the start time, location, atmosphere, expected cost, and any dietary restrictions in advance.
If you have religious considerations, allergies, or foods you'd rather avoid, let the organizer know early to make things smoother.
For vegetarian or halal needs, the organizer may be able to choose a venue that can accommodate you.
If you can only stay for part of the evening, mentioning this in advance helps everyone plan around it.
A quick heads-up beforehand makes it easier for the host to manage the schedule.
Final Thoughts: Enjoying a Bōnenkai with Confidence
A bōnenkai is a Japanese year-end dinner and social gathering deeply rooted in the culture of marking the season's close.
It's cherished as a way to reflect on the past year and strengthen connections with others.
Even as a first-timer, keeping in mind to wait for the toast, be considerate of others, and not push yourself too hard will help you join in comfortably.
If you have the chance during your trip, treat it as an opportunity to experience Japan's distinctive end-of-year atmosphere.
