The company was first established in August 1992 as a limited company under the name Studio DNA whose main purpose was to edit shōnen manga. In January 1998, Studio DNA became a public company and moved from merely editing to now being a publishing company. In December 2001, a publishing company was formed named Issaisha which started the shōjo manga magazine Monthly Comic Zero Sum. In March 2005, Studio DNA and Issaisha merged into the current Ichijinsha company.[1] In October 2016, Ichijinsha was acquired by Kodansha and became its wholly owned subsidiary.[2]
