How to say "reveal" in Japanese

Choosing the right word
  • 打ち明けるうちあけるCommon
    ichidan verb, transitive verbCovers revealing something private—one's feelings, worries, or a secret—by confiding it to someone trusted. The nuance is opening up voluntarily, so it suits heartfelt disclosure rather than exposing facts.
    私は彼かれに心配しんぱい事ことを打ち明うちあけた。↗
    I confided my troubles to him.
  • ばらすCommon
    godan verb, transitive verbReveals or exposes a secret, but colloquially and often with a careless or betraying nuance, like letting a secret slip or spilling it. Avoid it for sincere, deliberate disclosure; it can sound like blabbing.
    私は彼かれの秘密ひみつをばらすと脅おどしをかけた。↗
    I threatened to reveal his secret.
  • 出すだすJLPT N5approx.Common
    godan verb, transitive verbMatched to 'reveal' only through the broad sense of putting something out or showing it. For most secret-revealing senses this is seldom the word you want; think of it primarily as 'put out, take out, show'.
    この件けんでは名前なまえを出だしたくない。↗
    I want to remain anonymous in this.
  • 表すあらわすJLPT N3approx.Common
    godan verb, transitive verbCovers revealing in the sense of showing or displaying something outwardly—expressing feelings, qualities, or meaning so they become visible. It is not about disclosing secrets but about expression and representation.
    ご自分じぶんの栄光えいこうを現あらわされた。↗
    He thus revealed his glory.
  • 明かすあかすJLPT N1approx.Common
    godan verb, transitive verbThe straightforward word for revealing or divulging secrets, facts, or plans—making hidden things known. It fits both deliberate disclosure and revealing the truth, and is a safe choice for most 'reveal a secret' contexts.
    これは秘密ひみつです。他人たにんに明あかさないでください。↗
    This is a secret. Keep it to yourself.

For revealing secrets or feelings use 「打ち明ける」 (confide), 「明かす」 (divulge), or colloquial 「ばらす」 (blab); 「表す」 is for outward expression, and 「出す」 usually means simply putting something out rather than revealing.
