noun
pornographic book (Edo period)
Historical term for erotic literature or illustrated books from the Edo period. Not used for modern pornography.
江戸時代の好色物は、浮世絵とともに人気を博した。
Edo-period pornographic books were popular alongside ukiyo-e prints.
Compound of 好色 (こうしょく, 'lustful, lewd') and 物 (もの, 'thing, object'). The exact historical derivation is uncertain, but it follows a common pattern for naming types of books or objects.
