A casual party or get-together (often among students or colleagues), commonly held as a social mixer.
今週の金曜にサークルのコンパがあるから楽しみだ。
I'm looking forward to the club's party this Friday.
コンパは新入生と先輩が交流するいい機会だ。
A konpa is a good opportunity for new students and upperclassmen to interact.
週末は友達と飲み会ではなく小さなコンパを開いた。
Instead of a big drinking party, I held a small get-together with friends over the weekend.
