How to say "indecent" in Japanese

Choosing the right word
  • 下品げひんJLPT N2approx.Common
    na-adjective, nounCovers 'indecent' in the sense of vulgar or crude — coarse jokes, language, or behavior that lack refinement. The word to reach for when the emphasis is on bad taste.
    He haunts the lowest resorts.
  • 見苦しいみぐるしいJLPT N1approx.Common
    i-adjectiveCovers 'indecent' as unseemly: conduct or a scene that is unpleasant or embarrassing to watch, such as an ugly quarrel. Less about vulgarity than about being hard to look at.
    ここだけの話はなしだけれど、あの太ふとった見苦みぐるしい魔女まじょは減量げんりょう中ちゅうなのだ。↗
    Between ourselves, the fat ugly witch is on a diet.
  • みっともないJLPT N2approx.Common
    i-adjectiveCovers 'indecent' as improper or disgraceful in appearance or behavior — something that makes the person look bad. Often said of unseemly dress, posture, or public conduct.
    人前ひとまえでああいうみっともないことはするな。↗
    Don't do such a shameful thing in public.
  • 不謹慎ふきんしんCommon
    na-adjective, nounCovers 'indecent' only as immodest or lacking tact — remarks that treat serious matters lightly. For sexual indecency this is not the word; it is really about indiscretion.
  • エッチCommon
    na-adjective, nounCovers 'indecent' in the sexual sense: lewd or dirty talk, jokes, or content. This is the word for risqué, sexual indecency, not for crude taste or unseemly conduct.
    私よりもっとエッチな人ひともいて安心あんしんしました。↗
    I was relieved that there are people more wanton than me.

For sexual lewdness use 「エッチ」; for vulgar, crude taste or behavior 下品; for unseemly, embarrassing appearance or conduct 「見苦しい」 or 「みっともない」; for tactless, immodest remarks about serious matters 不謹慎.
