How do you say goodby in Japanese?

Answer 1

You may say 'ja ne' or 'mata ne,' or to coworkers/colleagues you may say 'otsukaresama.' When you don't plan on seeing someone for a very long time, you may say 'sayonara.' Written in the same order that they occur here, they are: じゃね　またね　お疲れ様　さようなら

Answer 4
