Seinen (青年) is a manga genre read by the young adult male audience. Readers range from high school students to working-class employees. The average age of seinen manga readers is 18 to 40 years old. Seinen series can be found in publications related with topics like “mania and moe”.
Seinen manga often gets mixed with other manga genres. The definition of shonen genre is so vague, it gets compared with manga for younger children. It is easy to distinguish shojo manga because of its target demographic. The youth reads manga series with unisex themes. This allows unisex-themed manga to have more female readers. Yet, publishers still had to label their manga whether it’s for children or not. Factors like art style and plot themes make it more difficult to categorize seinen. Seinen manga may include sexual content, yet it distances itself from adult manga. Some of the iconic seinen manga over the decades are JoJo’s Bizarre Adventures, Ghost in the Shell, Berserk, Oh My Goddess, K-ON!, and Mushishi.
The kanji 青年 comprises of two kanji: 青 (sei) or young/fresh/blue, and 年 (nen) or year/age. It is based on the same Chinese term “qīngnián” or adolescent/young adult. Seinen may have a close meaning with shonen but the context is different.
Weekly Manga Times is one of Japan’s earliest weekly manga magazines. First released in 1956, it publishes new chapters every Friday. Every cover often features illustrated paintings of young ladies. Sometimes they show main protagonists from their serialized manga series. The original target demography of Weekly Manga Times were middle-aged male readers. Some of the common themes in Weekly Manga Times are about erotica and the life of yakuza.
Other seinen manga magazines like Weekly Young Magazine have images of scantily-clad gravure idols to attract older and mature readers. The other manga magazine published along with Weekly Manga Times were Weekly Shonen Magazine and Weekly Shonen Sunday.
Other manga magazine companies followed suit on publishing diverse stories. Classic manga series for younger men such as Lupin III, Lone Wolf and Cub, and Crayon Shin-Chan were published in Weekly Manga Action. In 1968, Big Comics published Golgo 13, one of the most famous seinen manga in the industry. Big Comics Original published Tsuribaka Nisshi in 1972, which eventually turned into a movie franchise.
Shueisha joined the seinen manga publishing scene in 1979. They created Weekly Young Jump that features more serious, daring, and intense stories compared to Weekly Shonen Jump. It is successful enough to launch several seinen manga titles in various media formats. Some of the stories have been adapted into live-action series such as Gantz and Tokyo Ghoul.
Seinen in Modern Times
The topics and stories in seinen manga are very diverse compared with shonen manga. This includes cartoonish mischief, historical adventures, interpersonal relationships, grotesque violence, slice of life, grim and serious tone, more realistic and grounded premise, taboo ideas and so much more. Having deeper themes and stories mean that manga does not only cater to children and teenagers. Seinen manga accommodates a larger audience despite the age restrictions. Readers can enjoy topics beyond the scopes of shonen manga.
