How to say "conviction" in Japanese

Choosing the right word
  • 確信かくしんJLPT N1approx.Common
    noun, suru verb, transitive verbConviction as a firm, confident belief that something is true; the feeling of being sure. Use it when speaking of being convinced of something rather than of principles one lives by.
    私は君きみの援助えんじょを確信かくしんしている。↗
    I am assured of your help.
  • 信念しんねんCommon
    nounConviction as a belief or faith held deeply and steadily, something that guides a person's conduct. This is the word for the convictions someone lives by.
    彼かれの信念しんねんは何事なにごとにも揺ゆるがなかった。↗
    Nothing could sway his conviction.
  • 信条しんじょうCommon
    nounConviction as a creed or article of faith: a principle one professes and tries to keep to. Fits a stated personal credo or maxim more than a momentary feeling of certainty.

    He makes a religion of never wasting a penny.
  • 断罪だんざいCommon
    noun, suru verb, intransitive verbConviction in the legal sense — a judgment that someone is guilty of a crime — with a strong nuance of condemnation. It is not the word for conviction as a belief.
  • 所信しょしんCommon

Choose 確信 for the feeling of being certain something is true, 信念 for deeply held guiding beliefs, 信条 for a professed creed or principle, 所信 for one's own stated convictions, and 断罪 for legal conviction, a judgment of guilt.
