How to say "disclose" in Japanese

• 打ち明けるうちあけるCommon
  ichidan verb, transitive verbFor disclosing something personal one has kept inside — feelings, worries, secrets — to another person; the 'confide' nuance is central, so it suits heart-to-heart disclosure rather than public or official statements.
  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 verbColloquial: spilling or exposing a secret, often carelessly or deliberately. It is seldom the word you want for formal or official disclosure; think 'blab' or 'let the cat out of the bag'.

  I threatened to reveal his secret.
• 明かすあかすJLPT N1approx.Common
  godan verb, transitive verbThe general, neutral choice: revealing or divulging a secret or fact that has been kept hidden, in everyday talk and in news or official contexts alike.
  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.
• 漏らすもらすJLPT N1approx.Common

  She let the secret out.
