How to say "misconduct" in Japanese

Choosing the right word
  • 非行ひこうJLPT N1approx.Common
    no-adjectiveMisconduct in the sense of delinquency — wrongdoing by young people. Typical context: a teenager's repeated misbehavior discussed by parents, schools, or authorities.
    学校がっこうをさぼるのは非行ひこうの第だい一いち段階だんかいである。↗
    Cutting school is the first stage of delinquency.
  • 不義ふぎCommon
    no-adjectiveIts core senses are immorality and injustice; 'misconduct' is a marginal rendering. Seldom the word you want for concrete misdeeds — it names moral wrongness itself.
  • 不祥事ふしょうじCommon
    nounMisconduct by companies, officials, or organizations — wrongdoing that comes to light and turns into a scandal. Use it for corporate or political misconduct.
    Despite their own scandals, the police continue to make arrests as though nothing had happened at all.
  • 不心得ふこころえCommon
    noun, na-adjectiveReally means indiscretion, imprudence, or rudeness — a lapse in judgment or manners. Seldom the word you want for 'misconduct'; its misbehavior sense is minor.
  • 不始末ふしまつCommon
    noun, na-adjectiveMisconduct in the sense of mismanagement or malpractice: careless, improper handling of money or duties. Fits when funds or business have been handled badly.
    彼かれは部下ぶかの不始末ふしまつを見みつけた。↗
    He detected his men's misconduct.

Choose by the kind of wrongdoing: delinquent behavior is 非行, misconduct that becomes a public scandal is 不祥事, mismanagement of money or duties is 不始末, while 不義 and 不心得 are marginal choices for this sense.
