How to say "confidence" in Japanese

Choosing the right word
  • 信用しんようJLPT N3approx.Common
    noun, suru verb, transitive verbConfidence as trust placed in another person or party — believing what they say and relying on them. It also covers reputation. It is not the word for confidence in your own abilities.
    私はもう彼かれを信用しんようしない。↗
    I do not trust him any longer.
  • 自信じしんJLPT N1approx.Common
    nounThe word for confidence in oneself: belief in your own abilities or judgment. When English 'confidence' means self-assurance rather than trust in others, this is the word you want.
    君きみは自分じぶんが申し立もうしたてていることに自信じしんがありますか。↗
    Are you sure of your facts?
  • 信頼しんらいJLPT N3approx.Common
    noun, suru verb, transitive verbConfidence in another person or thing: trust, faith, and reliance. Use it for 'I have confidence in her' — the sense of counting on someone — rather than for confidence in your own abilities.
    確たしかに彼かれは信頼しんらいできます。↗
    You can certainly rely on him.
  • 確信かくしんJLPT N1approx.Common
    noun, suru verb, transitive verbConfidence as certainty — a firm conviction that something is true or will happen. This is the 'confident' of 'I am confident that he is right', not confidence in a person or in yourself.
    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.
  • 信望しんぼうCommon
    nounThe confidence and esteem in which a person is held by others, shading into popularity. Seldom the word you want for plain 'confidence'; it really describes a trusted, well-liked figure.
    彼女かのじょはその町まちでの信望しんぼうを得えた。↗
    She acquired credit with in the town.

Choose 自信 for confidence in yourself, 信用 and 信頼 for confidence in others (trust and reliance), 確信 for confident certainty that something is true, and 信望 for the confidence and esteem a person commands.
