List of manga magazines in the context of Shōnen manga

Shōnen manga (少年漫画; lit. "boys' comics", also romanized as shonen, shounen or syônen) is an editorial category of Japanese comics targeting an audience of both adolescent boys and young men. It is, along with shōjo manga (targeting adolescent girls and young women), seinen manga (targeting young adults and adult men), and josei manga (targeting adult women), one of the primary demographic categories of manga and, by extension, of Japanese anime. Shōnen manga is traditionally published in dedicated manga magazines that often almost exclusively target the shōnen demographic group.

Of the four primary demographic categories of manga, shōnen is the most popular category in the Japanese market. While shōnen manga ostensibly targets an audience of young males, its actual readership extends significantly beyond this target group to include all ages and genders. The category originated from Japanese children's magazines at the turn of the 20th century and gained significant popularity by the 1920s.

Nakayoshi (なかよし; lit. 'Good Friend') is a monthly shōjo manga magazine published by Kodansha in Japan. First issued in December 1954, it is a long-running magazine with over 70 years of manga publication history. Notable titles serialized in Nakayoshi include Princess Knight, Candy Candy, Pretty Guardian Sailor Moon, Cardcaptor Sakura and Pretty Cure. Roughly the size of a phone book (hence the term "phone book manga"), the magazine generally comes with furoku, or small gifts, such as pop-out figures, games, small bags, posters, stickers, and so on. The furoku is an attempt to encourage girls to buy their own copies of the magazine rather than just share with a friend.

It is one of the best-selling shōjo manga magazines, having sold over 400 million copies since 1978. In the mid-1990s, Nakayoshi retailed for 400 yen and had an average of 448 pages. The estimated average circulation of Nakayoshi at this time was 1,800,000. Its circulation peaked at 2,100,000 in 1993. In 2007, its circulation was 400,000. During the 1990s, then editor-in-chief, Yoshio Irie attempted to move the magazine away from "first love" stories and introduced several fantasy manga such as Sailor Moon. During that period, Nakayoshi pursued a "media-mix" campaign, which involved close coordination of the magazine, anime productions based on the manga, and character merchandising. Nakayoshi is also published on the 3rd of each month.

Shōjo manga (少女漫画; lit. 'girls' comics', also romanized as shojo or shoujo) is an editorial category of Japanese comics targeting an audience of adolescent girls and young adult women. It is, along with shōnen manga (targeting adolescent boys), seinen manga (targeting young adult and adult men), and josei manga (targeting adult women), one of the primary editorial categories of manga. Shōjo manga is traditionally published in dedicated manga magazines, which often specialize in a particular readership age range or narrative genre.

Shōjo manga originated from Japanese girls' culture at the turn of the twentieth century, primarily shōjo shōsetsu (girls' prose novels) and jojōga (lyrical paintings). The earliest shōjo manga was published in general magazines aimed at teenagers in the early 1900s and began a period of creative development in the 1950s as it began to formalize as a distinct category of manga. While the category was initially dominated by male manga artists, the emergence and eventual dominance of female artists beginning in the 1960s and 1970s led to significant creative innovation and the development of more graphically and thematically complex stories. Since the 1980s, the category has developed stylistically while simultaneously branching into different and overlapping subgenres.
