Kanpai
Cheers, Toast
noun, verbal noun
You dry out your cup of liquid after saying Kanpai, or cheers!
乾杯 means toasting with your drink and is how you say "Cheers!" in Japanese. It literally means "dry your cup" (drink up), so traditionally, people would finish their drink after saying it. But it's much more relaxed nowadays—most people just take a sip for 乾杯.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Just watch out for the はい turning into ぱい!
みんなで乾杯しましょう！
Let's all toast together!
三年ぶりの再会に、乾杯！
Cheers to our first reunion after three years!
少しおくれるので、先に乾杯して始めてください。
I'll be a bit late, so please kanpai without me and start the party.
さあ、乾杯、乾杯！それ、ぐいと一杯、飲み干したまえ。
Alright, cheers cheers! Hey, bottoms up!
