How to say "achieve" in Japanese

Choosing the right word
  • 果たすはたすJLPT N1approx.Common
    godan verb, transitive verbThis covers achieve in the sense of fulfilling something expected or intended — a duty, role, promise, or mission. It fits contexts like accomplishing the purpose one has been aiming at.
    君きみはその義務ぎむを果はたすべきである。↗
    You must perform your duty.
  • 成し遂げるなしとげるCommon
    ichidan verb, transitive verbCovers achieve as accomplishing or completing something, with the nuance of seeing a task through to the very end; it fits a project, plan, or undertaking that is finally brought to completion.
    あなたは、目的もくてきを成し遂なしとげましたか。↗
    Did you accomplish your purpose?
  • 遂げるとげるJLPT N1approx.Common
    ichidan verb, transitive verbA counterpart of 成し遂げる that frames achievement as the reaching of an end; it suits talk of achieving a goal or purpose, as in attaining success after working toward it.
    The rōnin attained their long-cherished ambition.
  • 勝ち取るかちとるCommon
    godan verb, transitive verbReally a word for winning: it covers achieve only when something is gained against rivals or through hard struggle — a victory, a position, or a right; not for simply accomplishing a task.
    彼かれはチェスのトーナメントで優勝ゆうしょうを勝ち取かちとった。↗
    He carried off the first prize at the chess tournament.
  • 勝ち得るかちえるCommon
    ichidan verb, transitive verbLike 勝ち取る, this is for achievements that are won rather than simply done; it presents the thing as gained or attained — the prize of victory or hard-fought effort, not of routine work.
    彼かれの成功せいこうは大おおきな犠牲ぎせいをはらって勝かち得えたものであった。↗
    His success was purchased dearly.

Use 「果たす」 for fulfilling a duty, role, or promise; 「成し遂げる」 or 「遂げる」 for carrying an undertaking through to completion; 「勝ち取る」 and 「勝ち得る」 only when the thing is won against rivals or through hard-fought effort.
