How to say "composed" in Japanese

Choosing the right word
  • 平気へいきJLPT N2approx.Common
    na-adjective, nounCovers 'composed' in the sense of being cool and unconcerned under pressure or after something shocking. It often carries a hint of nonchalance or not letting something bother you, as in staying 平気 before an exam or after bad news.
    彼かれは平気へいきでうそをつく。↗
    He has no scruples about lying.
  • 平然へいぜんCommon
    taru-adjective, adverb (with と)Also about keeping a cool, composed exterior, but focuses on the unruffled outward manner—facing something calmly and quietly as if nothing were wrong. Typical of remaining 平然 in the face of criticism or danger.
    その政治家せいじかは平然へいぜんと賄賂わいろを受け取うけとり、全すべての契約けいやくの5%が濡れ手ぬれてに粟あわで彼かれの懐ふところに入はいった。↗
    The politician had sticky fingers, and 5% of every contract ended in his pocket.
  • 泰然たいぜんCommon
    taru-adjective, adverb (with と)Refers to composed dignity and self-possession, a firm, unshaken bearing rather than casual coolness. Suits describing a leader or elder who stays 泰然 when events turn turbulent; more formal in flavor than 落ち着いた.
    彼かれはその知しらせにも泰然たいぜんとしていた。↗
    He heard the news calmly.
  • 落ち着いたおちついたCommon
    prenominal modifierThe everyday word for a calm, composed person or even a settled atmosphere and manner. If you simply want to say someone is composed, level-headed, or unruffled, this is usually the safest and most natural choice.
  • 重厚じゅうこうCommon
    na-adjective, nounGlosses include 'grave' and 'solid' rather than composure, and this is seldom the word you want for 'composed'. It really describes a profound, weighty, grave quality—in character, presence, or style—not staying calm under stress.

For emotional composure use 平気 or 平然; 「落ち着いた」 is the everyday all-purpose calm-composed adjective; 泰然 suggests dignified self-possession; 重厚 describes gravity of character, not composure.
