How to say "unsettled" in Japanese

Choosing the right word
  • 不定ふていCommon
    no-adjective, na-adjectiveCovers the sense of uncertain, indefinite, or unfixed — plans, dates, or conditions that are not settled or decided. Use it when 'unsettled' essentially means 'not yet fixed or determined'.
  • 物騒ぶっそうJLPT N2approx.Common
    na-adjective, nounBest for the troubled or dangerous sense: times or situations that feel unsafe and unsettling. Its core meaning is dangerous or alarming, so it suits 'unsettled' only when unrest or threat is implied.
    地震じしんの後あと、この辺あたりは物騒ぶっそうだ。↗
    After the earthquake the neighbourhood felt insecure.
  • 流動的りゅうどうてきCommon
    na-adjectiveUsed for fluid, unstable situations — markets, politics, or circumstances that keep shifting and have not settled into a stable state. It captures 'unsettled' as 'in flux' rather than merely undecided.
    経済けいざい情勢じょうせいは流動的りゅうどうてきである。↗
    Economic conditions are in a state of flux.
  • 未解決みかいけつCommon
    no-adjective, na-adjectiveThe word for unresolved or pending matters — problems, questions, disputes, or cases that remain unsettled because no solution or conclusion has been reached. This is the usual choice for 'unsettled' in that legal or problem-solving sense.
    2つの問題もんだいが未解決みかいけつのままであった。↗
    Two problems remained unsolved.
  • 不穏ふおんCommon
    na-adjective, nounDescribes disquieting, turbulent, or restless conditions — an atmosphere of unrest or signs of trouble. It fits 'unsettled' when the emphasis is on tension or impending disturbance; its glosses do not include it directly, so it is a looser match.
    軍部ぐんぶに不穏ふおんな動うごきが見みられる。↗
    There seem to be dangerous developments in the military.

'Unsettled' splits by sense: 未解決 for unresolved matters, 不定 for uncertain/unfixed things, 流動的 for fluid situations, and 物騒 or 不穏 for troubled or disquieting conditions.
