How to say "quick-tempered" in Japanese

Choosing the right word
  • 性急せいきゅうCommon
    na-adjective, nounA common word whose core sense is haste: it describes someone who acts rashly or in too much of a hurry. Use it when 'quick-tempered' means hasty rather than quick to flare up.
    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.
  • 気早きばや
    na-adjective, nounA less common word covering the impatient side of 'quick-tempered': someone who cannot wait and loses patience quickly. The nuance is impatience rather than outright anger.
  • 気が短いきがみじかい
    expression, i-adjectiveA less common phrase, literally 'one's temper is short': it describes a person with little patience who flares up quickly over delays and small annoyances.
    彼女かのじょは気きが短みじかいのが玉たまにきずだ。↗
    A quick temper is the only defect in her character.
  • 気の短いきのみじかい
    i-adjectiveIdentical in meaning to 気が短い — quick-tempered, impatient; this is simply the form with の, used when the phrase comes directly before the noun it describes.
  • 短腹たんぱら
    na-adjectiveA less common word combining 'quick-tempered' with 'easily offended' — someone quick to take offense. Unless that nuance is exactly what you want, it is seldom the word you need.

For haste and rashness choose 性急; for impatience and a short fuse choose 気早, 「気が短い」 or its pre-noun form 「気の短い」; 短腹 centers on taking offense easily.
