  • As "here": Response when name is called (roll call, etc.)
  • As attention-getter: Similar to "okay" or "all right"

Watch out

  • As a backchannel (あいづち) while someone is talking, はい shows you are listening, not that you agree.
  • In answer to a negative question, はい confirms the negative (the opposite of English):
  • 「行(い)かないの?」「はい。」 = "You're not going?" "That's right (I'm not going)."

Similar words

  • ええ: softer, slightly more casual "yes"
  • うん: casual "yeah"
