How to say "evidence" in Japanese

Choosing the right word
  • 証拠しょうこJLPT N1approx.Common
    nounEvidence as proof: facts, objects, or testimony that establish something is true, the word you reach for in court cases, investigations, and everyday argument.
    この証拠しょうこは彼かれにとって不利ふりだった。↗
    This evidence was against him.
  • 証あかしJLPT N1approx.Common
    nounProof or testimony that attests to something, or a sign that shows it; for material evidence in a court or investigation, 証拠 is the word you want.
    しかし、あなた方かたは私わたしたちの証あかしを受け入うけいれません。↗
    But still you people do not accept our testimony.
  • 形跡けいせきCommon
    nounEvidence as traces or telltale signs that someone or something has been present or that something has happened, rather than proof supporting a claim.
    その家いえには人ひとの住すんでいる形跡けいせきはなかった。↗
    The house gave no sign of life.
  • 跡形あとかたCommon
    nounA trace or vestige of something that existed and is now gone; it really means what remains behind, so it is seldom the word for evidence as proof.
    バブルが跡形あとかたもなく消え去きえさったからである。↗
    That's because the bubble vanished into thin air.
  • 痕跡こんせきCommon
    nounA trace, mark, or vestige left by something that was present or once existed; like the other trace words, not used for evidence as proof in an argument.
    アテネへ向むかう一いち隻せきの貨物船かもつせんが何なんの痕跡こんせきも残のこさずに地中海ちちゅうかいで沈没ちんぼつした。↗
    A cargo vessel, bound for Athens, sank in the Mediterranean without a trace.

Choose 証拠 for evidence as proof establishing a fact (courts, investigations, arguments); 証 for attesting proof, testimony, or a sign; and 形跡, 跡形, 痕跡 for evidence as traces or vestiges left behind.
