How to say "determination" in Japanese

Choosing the right word
  • 決定けっていJLPT N3approx.Common
    noun, suru verb, transitive verb, intransitive verbHere 'determination' means the settling of something — a decision reached and fixed, as when a date or outcome is decided. It is not the word for inner resolve.
    われわれは最終的さいしゅうてき決定けっていを行おこなった。↗
    We've made a final decision.
  • 決断けつだんJLPT N1approx.Common
    noun, suru verb, transitive verbThe act of making a hard decision and committing to it — determination as decisiveness in a pressing situation. It points to the moment of choosing, not to lasting grit or a settled outcome.
    決断けつだんの日ひは近ちかい。↗
    The day of decision is at hand.
  • 決心けっしんJLPT N3approx.Common
    noun, suru verb, transitive verbDetermination as a resolve you form in your own mind — making up your mind to do something, such as give something up or start anew — and the resolve itself once formed.
    すぐ決心けっしんするようにしてください。↗
    Try to make up your mind soon.
  • 決意けついJLPT N1approx.Common
    noun, suru verb, transitive verbA firm, weighty resolve — determination solemnly formed or declared, as when someone announces their intention anew. It sits close to 決心 but carries more gravity.
    彼女かのじょは私に自分じぶんの決意けついを知しらせてくれた。↗
    She informed me of her decision.
  • 根性こんじょうCommon
    nounDetermination in the sense of grit: sheer guts and stubborn willpower that keep someone going. It is not about making a decision, and it can carry a rough, stubborn flavor.
    セッティングは整ととのえておいたから、後あとはまーくんが根性こんじょう見みせなきゃダメだからね?↗
    I've set the stage so now you just have to show some guts, OK?

For 'determination' as a settled decision use 決定, as a hard choice made decisively 決断, as resolve to act 決心 or the weightier 決意, and as sheer grit 根性.
