How to say "collected" in Japanese

• 深沈しんちん
  taru-adjective, adverb (with と), na-adjectiveCovers 'collected' as calm, composed, and self-possessed in demeanor. It carries a literary, descriptive nuance for a quietly deep composure, and being less common, it is seldom the word a learner needs in everyday speech.
• 鷹揚おうよう
  na-adjective, nounCovers 'collected' as placid, composed, and cool under pressure. It suggests a broad, easygoing unflappability rather than tense self-control; being less common, it suits written or descriptive contexts more than casual conversation.

Both words render 'collected' only in the sense of calm, self-possessed demeanor; since both are less common, prefer everyday alternatives unless describing a composed temperament with a literary flavor.
