How to say "belief" in Japanese

Choosing the right word
  • 宗教しゅうきょうJLPT N3approx.Common
    nounCovers 'belief' in the sense of a religion or religious affiliation, as in asking what someone's religion is. It really means religion itself, so it is not the word for a personal belief or conviction.
    For a start, I visited Jerusalem - a sacred place for three major religions.
  • 信仰しんこうJLPT N3approx.Common
    noun, suru verb, transitive verbReligious faith or belief in a religion, viewed as an inner commitment or creed. Use this when 'belief' means faith in a deity or teaching, as in one's religious faith being deep.
    キリスト教きりすときょうを信仰しんこうしていますか。↗
    Do you believe in Christianity?
  • 信念しんねんCommon
    nounA personal belief or conviction held firmly, whether moral, philosophical, or practical. This is the usual word for non-religious 'belief', as in believing strongly that effort will be rewarded.
    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.
  • 確信かくしんJLPT N1approx.Common
    noun, suru verb, transitive verbA firm conviction or confident belief that something is true or will happen. It emphasizes certainty about a specific matter rather than a general creed, as in being convinced of victory.
    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.
  • 信心しんじんCommon
    noun, suru verb, transitive verbFaith, piety, or devotion in a religious sense, often with an earnest, devoted nuance. For 'belief' it is largely limited to religious faith, and 信仰 is the more neutral everyday choice.

Choose 宗教 for religion as an institution, 信仰 or 信心 for religious faith, 信念 for personal convictions, and 確信 for firm confidence that something is true.
