How to say "discontent" in Japanese

Choosing the right word
  • 不満ふまんJLPT N3approx.Common
    noun, na-adjectiveThe default word for discontent as a general feeling of dissatisfaction with a situation, treatment, or state of affairs. Covers displeasure and complaints, whether kept to oneself or voiced.
    何なんがそんなに不満ふまんですか。↗
    What made you so dissatisfied?
  • 不平ふへいJLPT N3approx.Common
    no-adjective, na-adjectiveDiscontent in the sense of complaint or grievance: grumbling about something felt unfair or unwarranted. It leans toward the dissatisfaction one expresses rather than quietly holds.
    君きみはいつも不平ふへいを言いっている。↗
    You are always complaining.
  • 不服ふふくJLPT N1approx.Common
    noun, na-adjectiveDiscontent aimed at a decision, ruling, or result one finds unacceptable — objection or disapproval rather than a vague feeling of discontent. For discontent in general, use 不満 instead.
    彼かれは不服ふふくそうに口くちをとがらせた。↗
    He pouted with dissatisfaction.
  • 不満足ふまんぞくCommon
    noun, na-adjectiveThe state of being unsatisfied or displeased with something judged inadequate; it often describes something as unsatisfactory rather than naming the feeling itself. For the emotion of discontent, 不満 is the usual choice.
    あなたは満足まんぞくしていますか、それとも不満足ふまんぞくですか。↗
    Are you satisfied or dissatisfied?
  • 不足ふそくJLPT N3approx.Common
    noun, na-adjectivePrimarily a shortage or insufficiency — a lack of something needed. Its use for 'discontent' or complaint is marginal, so it is seldom the word you want here.

Use 不満 for discontent in general; 不平 for voiced complaints or grievances; 不服 for objection to a decision or result; 不満足 for the state of being unsatisfied; 不足 mainly means shortage, not discontent.
