(わいせつ)

わいせつ
adjective-na
obscene; indecent; lewd
1. obscene; indecent; lewd (especially in a legally or socially unacceptable way)
Describes sexual content, acts, or depictions considered a violation of public decency. In Japanese, 猥褻(わいせつ) is primarily a legal and news-media term: it appears in criminal-law names of offenses (強制(きょうせい)猥褻(わいせつ)(ざい) 'indecent assault', 猥褻(わいせつ)物頒布(ぶつはんぷ)(ざい) 'distribution of obscene materials') and in reports of arrests for indecent exposure, groping, or sexual molestation. Much more formal and more strongly negative than everyday words like エッチ or いやらしい.
猥褻(わいせつ)表現(ひょうげん)
Obscene expression.
容疑者(ようぎしゃ)猥褻(わいせつ)行為(こうい)(うたが)いで逮捕(たいほ)された。
The suspect was arrested on suspicion of indecent conduct.
この法律(ほうりつ)猥褻(わいせつ)(ぶつ)頒布(はんぷ)(きん)じている。
This law prohibits the distribution of obscene materials.
表現(ひょうげん)自由(じゆう)猥褻(わいせつ)境界線(きょうかいせん)をどう()くかは、(ふる)くから議論(ぎろん)されてきた(むずか)しい問題(もんだい)である。
Where to draw the line between freedom of expression and obscenity has long been a difficult issue of debate.

Compound of (わい) ('disordered; lewd') and (せつ) ('familiar; vulgar'). Both kanji are outside the general-use list (non-常用(じょうよう)); news media often writes the word in hiragana (わいせつ) as a result — わいせつ}{事件(じけん), わいせつ}{行為(こうい).

USAGE:

  • Used as a na-adjective: 猥褻(わいせつ)画像(がぞう) ('obscene image'), 猥褻(わいせつ)言葉(ことば) ('lewd language').
  • Used as a bare prefix in legal and news compounds: 猥褻(わいせつ)行為(こうい) ('indecent conduct'), 猥褻(わいせつ)(ぶつ) ('obscene material'), 猥褻(わいせつ)事件(じけん) ('indecency case'), 強制(きょうせい)猥褻(わいせつ) ('indecent assault').
  • Much stronger and more formal than いやらしい ('lewd; creepy') or エッチ ('naughty'); carries the weight of moral and legal condemnation.

  • 猥褻(わいせつ)行為(こうい): indecent conduct / indecent act (esp. in criminal context)
  • 猥褻(わいせつ)(ぶつ): obscene material

LEGAL NOTE:
日本(にほん)刑法(けいほう) (Japanese Penal Code) uses 猥褻(わいせつ) as a legal technical term. In modern statutes, some offense names have been revised (e.g. '強制(きょうせい)わいせつ(ざい)' was restructured into '不同意(ふどうい)わいせつ(ざい)' in the 2023 revision), but 猥褻(わいせつ)/わいせつ remains the core word.
