How to say "hasty" in Japanese

Choosing the right word
  • na-adjective, nounCovers 'hasty' as a personality trait: someone impatient who cannot wait and acts too quickly. Typical of descriptions like a hasty, restless person rather than of the quality of the work done.
    An impatient driver forced his way through the crossing against the red light.
  • 性急せいきゅうCommon
    na-adjective, nounDescribes hasty, rushed action or judgment, often a person's tendency to rush into things; it overlaps with せっかち but stresses the rashness of hurried decisions and behavior.
    性急せいきゅうな判断はんだんは危険きけんです。↗
    Quick judgements are dangerous.
  • 拙速せっそくCommon
    na-adjective, nounCovers 'hasty' only for work or results done too quickly and therefore rough or slipshod; it never describes a person's temperament, so it is not the word for a hasty character.
  • 軽はずみかるはずみCommon
    na-adjective, nounCovers 'hasty' in the sense of rash and imprudent: acting or speaking without due thought. The emphasis falls on lack of forethought rather than on speed itself.
    君きみが彼かれの申し出もうしでを受うけるとは軽かるはずみだったね。↗
    It was foolish of you to accept his offer.
  • そそっかしいJLPT N2approx.Common
    i-adjectiveCovers 'hasty' as a trait of someone who does everything in a rush and is careless or thoughtless as a result; it describes the person or their manner, not the finished result.
    バスに傘かさを忘わすれるとは彼女かのじょはそそっかしい。↗
    It was careless of her to leave her umbrella in the bus.

Use 「せっかち」 or 「そそっかしい」 for impatient, careless temperaments, 性急 for rushed action or judgment, 「軽はずみ」 for rash, thoughtless behavior, and 拙速 only for work done quickly at the cost of quality.
