On March 4th, Ichijinsha celebrated the 20th anniversary of its trade name, and it has been announced that a commemorative project will be launched. As the first step, the 20th anniversary official website was opened, introducing congratulatory comments from over 50 bookstores and related parties. The official website will also include the company's history and media expansion history, and aims to be "a commemorative site that can be enjoyed and read by fans and related parties alike."
As the second part, a YouTube program has started in which the 20th anniversary mascot Ichijin-chan takes on various projects with all his might. The videos are scheduled to be updated on the first and third Wednesdays of every month. Projects beyond the third part are also planned.
The company was founded in August 1992 as an editing production company called Studio DeNA, which increased its capital in January 1998 and became a joint-stock company from a limited company, starting out as a publishing company while retaining its editing and production functions. It then merged with Ichijinsha, which was established in March 2005 for the purpose of publishing Monthly Comic Zero Sum, and changed its name to Ichijinsha, with Studio DeNA as the surviving company. In November 2016, it entered into a capital alliance with Kodansha and became a wholly owned subsidiary.
