忘年会（ぼうねんかい、bounenkai）
- year-end party

The word 忘年会 (ぼうねんかい) refers to a year-end party in Japan. It's a common social gathering held by companies, schools, or social groups at the end of the year to reflect on the past year, celebrate accomplishments, and socialize before the New Year. The main purpose is to "forget the year" – to let go of the stresses and difficulties of the past year and look forward to a fresh start. These parties often involve food, drinks, and entertainment.

You can use 忘年会 to talk about attending, planning, or reflecting on the year-end party. It is generally used when the event is approaching or has just occurred. You can use this word when talking with colleagues, friends, or family about the year-end festivities.

忘年会 is typically written in kanji, 忘年会, but you'll often see the reading, ぼうねんかい, written in hiragana above the kanji. There are no other common ways to write this word, and the okurigana is fixed.

There aren't many direct synonyms for 忘年会, as it is a specific cultural event. However, phrases that describe the activity could be considered similar, such as: ⚫︎ 年末のパーティー (nenmatsu no pātei): Year-end party ⚫︎ 納会 (nōkai): Year-end gathering (often used in companies)

There aren't specific antonyms, but you could consider the start of the year as the opposite time, or perhaps a formal business meeting as contrasting to its informal style.

The word is formed from the kanji 忘 (bō) meaning "to forget," and 年会 (nenkai) meaning "year-end gathering" or "annual meeting." Thus, the name 忘年会 literally translates to "forget-the-year gathering," reflecting its purpose of leaving the past year's troubles behind.
