founded 1976 (year 51)
Founded in 1976 as the limited company Akane, Akaneshinsha (茜新社) is based in Kanda-Misakicho, Chiyoda ward, Tokyo. Its flagship magazine is COMIC LO, launched in 2002, yet most of the practical work on both its magazines and its book editions is handled by its parent company, the editorial production company Comic House — a close two-in-one arrangement largely invisible from the outside. The firm also runs general-audience and boys' love imprints. It has no capital ties whatsoever to Akane Shobo, the long-established children's book publisher.

Kill Time Communication (キルタイムコミュニケーション) was born in 1995 out of the editorial production division of the advertising agency Micro House. Home to Comic Unreal and Nijigen Dream Magazine, it is a major stronghold of fantasy-oriented adult publishing; its sister company is Micro Magazine, known for light novels. In its early years the firm also published PC-building and video game magazines, and as of 2016 its best-selling title of all time was not an adult publication but a Pokémon strategy guide.

Established in 1985 as Shonen Shuppansha, the company took its present name, Core Magazine (コアマガジン), in a 1995 renaming — at which point the name "Gokigen Shuppansha" was reportedly also proposed, only to be dropped in the face of objections from all sides. An affiliate of Byakuya Shobo, it assumed its current form by consolidating that company's adult and subculture divisions. From its own building in Takada, Toshima ward, it keeps both wheels turning — adult and subculture alike — with titles ranging from Comic HOTMILK and Megastore to Jitsuwa BUNKA Taboo.

Wanimagazine (ワニマガジン社) was established in 1971 as a group company of KK Bestsellers and later became independent. It is known for a confusing coincidence: although it has no personal or capital ties to Wani Books, all three companies display a "reading crocodile" as their symbol. Its flagship magazine is COMIC Kairakuten, launched in 1994. Unusually art-minded for an adult publisher, the company also operates a gallery, a ristorante, and even a wine shop.
