How to say "vice" in Japanese

Choosing the right word
  • 悪徳あくとくCommon
    nounVice as moral corruption: dishonest, unscrupulous conduct, the opposite of virtue. The natural choice when condemning corrupt business or official behavior as immoral.
    怠惰たいだは悪徳あくとくのもと。↗
    Idle hands are the devil's tool.
  • 罪悪ざいあくCommon
    nounVice as sin: an act regarded as morally evil or wicked, not merely a bad habit. Suits moral or religious condemnation, where the deed is treated as sinful.
    大都会だいとかいには罪悪ざいあくがはびこっている。↗
    There is much crime in the big cities.
  • 不徳ふとくCommon
    na-adjective, nounVice as a person's lack of virtue: moral failing or depravity in someone's character or conduct. Emphasizes the absence of virtue in the person rather than any particular deed.
  • 悪事あくじCommon
    nounEvil deeds or wrongdoing — 'vice' only in the sense of wicked acts actually committed. Seldom the word for vice as a habit or character trait; think concrete misdeeds.
    他人たにんの悪事あくじを引き合ひきあいに出だして自分じぶんの悪事あくじの言い訳いいわけをすることはできない。↗
    Two wrongs don't make a right.
  • 悪習あくしゅうCommon
    nounVice as a bad habit or evil practice: a harmful custom or behavior pattern rather than a single wicked deed. Use it for vice in the habitual, practice sense.
    悪習あくしゅうに染そまるのは簡単かんたんだ。↗
    It's easy to fall into bad habits.

Choose 悪徳 for moral corruption or unscrupulousness, 罪悪 for sin and wickedness, 不徳 for a person's lack of virtue, 悪習 for bad habits or customs, and 悪事 only for concrete evil deeds.
