How to say "acknowledgement" in Japanese

Choosing the right word
  • 認知にんちCommon
    noun, suru verb, transitive verbAcknowledgement as recognizing something to be true or real; it overlaps with 'recognition' and 'cognition', so it points to mental acceptance of a fact rather than approval or consent.
  • 了承りょうしょうJLPT N1approx.Common
    noun, suru verb, transitive verbAcknowledgement as understanding and accepting a proposal, request, or arrangement; typical in business when you ask someone to take note of and go along with something.
    この件けんについてのあなたのお求もとめを了承りょうしょうします。↗
    Your request of this matter has been accepted.
  • 承認しょうにんJLPT N3approx.Common
    noun, suru verb, transitive verbAcknowledgement that amounts to approval: formally accepting or signing off on a request, plan, or document. It also covers 'recognition', so the emphasis is on granting acceptance, not merely noting something.
    私の提案ていあんを承認しょうにんしていただけますか。↗
    Could you approve my proposal?
  • 認容にんようCommon
    noun, suru verb, transitive verbA formal term for accepting or allowing something, especially upholding a claim in legal contexts; for everyday 'acknowledgement' it is seldom the word you want.
  • 礼状れいじょうCommon
    nounThe concrete sense of 'acknowledgement' as a written letter of thanks, sent in reply to a gift, favor, or kindness; it names the letter itself, not the act of acknowledging.
    あなたは彼かれらにお礼状れいじょうを書かくべきだと思おもいませんか。↗
    Don't you think you ought to write them a thank-you note?

Choose by sense: 認知 for recognizing a fact as true, 了承 for accepting a proposal or request, 承認 for approval or sign-off, 認容 for formal acceptance of a claim, and 礼状 for a written letter of thanks.
