Translation guide
In Japanese, the concept of pornography is expressed through several terms that differ in formality, medium, and nuance. The most common and neutral term is アダルト (adult), used as a prefix or standalone. More direct words like ポルノ (porn) are also used but can sound blunt. There are also native Japanese terms like わいせつ (obscene) used in legal contexts, and specific words for erotic books or images.
