Core Magazine owns a bookstore chain "Core Books" (コアブックス).
History
In July 2002, a special issue of Bubka magazine featured unauthorized childhood photos of several female idols, including Norika Fujiwara, Kyoko Fukada, and Natsumi Abe. A suit was started against Core Magazine for privacy violation.
In 2009, it was the top ero-manga publisher in Japan, with 76 titles, beating Akane Shinsha, which only had 65.
In July 2013, the head editor, Akira Ota, and the two staff members were arrested for having their manga shown partially uncensored. They pled guilty in December 2013 and apologized for their irresponsibility.
In September 2017, Komiflo announced in collaboration with Core Magazine that its titles would be available for streaming. Starting with Hotmilk, this expanded to include MegaStore in 2018.
