How to say "certificate" in Japanese

Choosing the right word
  • 証券しょうけんCommon
    nounA certificate in the financial sense — a security, bond, or the like. For certificates of other kinds it is seldom the word you want.
    彼女かのじょは例れいの金かねのインチキ証券しょうけん商法しょうほうに引ひっかかり持ち金もちがねのほとんどを失うしなってしまった。↗
    She was taken in by that fake gold certificate scandal and lost most of her money.
  • 証書しょうしょCommon
    nounA formal written document drawn up as proof of something. It suits official papers attesting a fact, though 証明書 is the more direct word for most certificates.
    Loan on deeds needed the joint surety.
  • お墨付きおすみつきCommon
    nounAn authorization or seal of approval from someone in authority, often used figuratively for an endorsement. Choose it when 'certificate' implies someone's backing rather than a document attesting facts.
  • 証明書しょうめいしょCommon
    nounA document certifying that a fact is true or that someone holds a status or qualification. This is typically the word you want for 'certificate' in its everyday sense.
    もし予防接種よぼうせっしゅ証明書しょうめいしょがあったらお持もちください。↗
    If you have a certificate of immunization, please bring it when you come.
  • 免状めんじょうCommon
    nounA licence or permit: an official document certifying that the holder is qualified to do something. Use it when 'certificate' means this credential rather than a document attesting a fact.

For a certificate attesting a fact or status, choose 証明書; for licences and permits, 免状; for formal written proof, 証書; for someone's endorsement or seal of approval, 「お墨付き」; 証券 is only for financial securities.
