How to say "dialogue" in Japanese

Choosing the right word
  • 対話たいわJLPT N1approx.Common
    noun, suru verb, transitive verb, intransitive verbThe default word for 'dialogue' as a mutual, two-way exchange between two people or sides, such as talks between groups or countries; it also covers conversation and discussion generally.
    この例れいにおいては、その二人ふたりの詩人しじんの対話たいわに関かんする正確せいかくな記述きじゅつがもたらされている。↗
    In this instance we are provided with an exact account of the conversation between the two poets.
  • 対談たいだんJLPT N1approx.Common
    noun, suru verb, transitive verb, intransitive verbA face-to-face talk between two people, typically one arranged and presented for an audience, as in a magazine interview or broadcast conversation; use it for that sense, not for dialogue in general.
    その上うえ、ある大学だいがく教授きょうじゅと対談たいだんしなければならない。↗
    In addition, I have to interview a professor.
  • 談話だんわCommon
    noun, suru verb, intransitive verbA formal word for talk or conversation; for the ordinary sense of 'dialogue' it is seldom the word you want — it is really used for remarks or a statement, especially one issued publicly.
    夕食ゆうしょく後ごの談話だんわで彼かれらは政治せいじについて話し合はなしあった。↗
    In their discourse after dinner, they talked about politics.
  • 問答もんどうJLPT N2approx.Common
    noun, suru verb, transitive verb, intransitive verbAn exchange of questions and answers between two sides; beyond the plain sense it often suggests a drawn-out or argumentative back-and-forth. Use it when 'dialogue' means a question-and-answer exchange rather than calm discussion.
  • 掛け合いかけあいCommon
    nounBanter or repartee: an exchange of lines between two people, or the trading of parts in a duet. For ordinary 'dialogue' it is seldom the word you want — it really refers to such interplay.

Choose 対話 for dialogue as a mutual exchange between two sides, 対談 for an arranged two-person talk, 問答 for question-and-answer exchanges, and treat 談話 and 「掛け合い」 as narrow or marginal choices.
