Translation guide
The English word "obscene" covers a range of meanings from sexually explicit to morally outrageous. In Japanese, the most common equivalent is わいせつ (waisetsu), but depending on context, other words like 卑猥 (hiwai), 下品 (gehin), or エロ (ero) may be more natural. This guide breaks down the main uses and provides natural Japanese expressions for each.
