Otsukare is an everyday Japanese expression used when someone finishes work, a performance or a difficult task, and it carries the sense of acknowledging effort rather than simply saying goodbye. The word has become familiar outside Japan through anime, Japanese workplaces shown on television and, more recently, livestreamers and VTubers who use it to close broadcasts and thank viewers for watching. Because it is short, polite and emotionally warm, it works as a shared sign-off in comments, chats and edits, where it signals that a long session has ended well.
