How to say "enthusiasm" in Japanese

Choosing the right word
  • 情熱じょうねつJLPT N1approx.Common
    nounCovers intense, burning enthusiasm directed at a cause, work, or person; the emotional-fire sense of 'passion'. Typical for describing someone's dedication to art, research, or love.
    彼かれの私に対たいする情熱じょうねつはさめない。↗
    His passion for me doesn't cool.
  • 熱意ねついJLPT N1approx.Common
    nounZealous, earnest enthusiasm shown in attitude and effort, often toward a task, study, or job. The natural word for workplace or school contexts, as in showing eagerness in an application or interview.
    彼女かのじょは自分じぶんの仕事しごとにぜんぜん熱意ねついを示しめさない。↗
    She shows no zeal for her work.
  • nounThe loanword for 'passion', used mainly as a punchy, slogan-like buzzword in advertising, sports, and motivational talk. For ordinary sentences 情熱 or 熱意 is usually the word you want.
    なにやら唸うなりながら、ほとばしるパッションをキャンバスにぶつけている!↗
    Groaning strangely she is hurling her overflowing passion onto the canvas!
  • 乗り気のりきCommon
    noun, na-adjectiveEnthusiasm as being keen or game for a particular plan or invitation — eagerness to join in, or the lack of it. Used of people's willingness toward something, not of deep inner passion.
  • 気負いきおいCommon
    nounA worked-up, girded eagerness or fervor, sometimes with a tense or overeager undertone. A narrower word than the others; it is often not the best choice for plain 'enthusiasm', which 熱意 or 情熱 express better.

For passionate, burning enthusiasm use 情熱 or 熱意; 「パッション」 is the loanword for 'passion' as a slogan-like buzzword; 「乗り気」 covers being keen on something; 「気負い」 leans toward eager, worked-up fervor.
