Light novels vs. Manga

Light novels are similar to manga in aesthetic characteristics and style, but they are considered prose works, designed as novels for a young audience. The text is written similarly to a novel, with illustrations added, often created by the writers themselves or more frequently by a character designer and sometimes by a mecha designer, with illustrator duties.

Despite their stylistic similarities to manga, light novels are considered prose works, intended as novels for teenagers or a young audience. Some LN have inspired various manga or anime, and therefore are seen as subgenres of manga, or as another type of comic. The style of light novels tends to be different from that of novels for a more mature audience.

LN are often adapted into manga and anime, making them a significant part of the Japanese pop culture industry. For instance, “Date A Live” is a popular light novel series that has been adapted into manga, anime, and even video games.

Physical books and digital format

Light novels are not exclusive to physical books; they also exist in digital format. Some LN begin as online serials self-published on blogs or forums. Publishers often pick up these titles, help the author revise them, and then release them as LN.

There are databases and resources dedicated to light novels, such as LNDB.info, which aims to be the most comprehensive database for LN, and Anime-Planet’s light novel database, which contains information about over 10,000 light novels.

In terms of illustrations, they typically feature manga-style drawings, often created by Japanese artists. These illustrations are an integral part of the light novel format, adding visual depth to the narrative and often influencing adaptations into manga or anime.
