Manga [SEP] Introduction
Manga (, ; Japanese: 漫画 ) are comics or graphic novels originating from Japan. Most manga conform to a style developed in Japan in the late 19th century, though the art form has a long prehistory in earlier Japanese art. The term "manga" (katakana: ; hiragana: ) is used in Japan to refer to both comics and cartooning. Outside Japan, the word is typically used to refer to comics originally published in the country. In Japan, people of all ages read manga. The medium includes works in a broad range of genres: action, adventure, business and commerce, comedy, detective, drama, historical, horror, mystery, romance, science fiction and fantasy, erotica ("hentai"), sports and games, and suspense, among others.
