IG Port
Japanese stock holder for entertainment media

IG Port, Inc. (Japanese: 株式会社IGポート, Hepburn: Kabushiki-gaisha Ai Jī Pōto) is a Japanese holding company that was established on December 1, 2007, as a result of a merger between the Japanese anime studio Production I.G and manga publisher Mag Garden.
History
The merger between Production I.G and Mag Garden was announced on July 4, 2007. Production I.G was transformed into a holding company a month ahead of the scheduled merger on December 1, 2007. Along with a name change, it transferred most of its former duties and management to a newly developed subsidiary also named "Production I.G". After the merger with Mag Garden by the stock exchange, IG Port now fully owned the "new" Production I.G, Mag Garden, and Xebec as its subsidiaries.
On September 19, 2014, IG Port announced that it would be forming a new animation production subsidiary, named Signal.MD, with a capital of ¥30 million. The company stated that the goal of the new subsidiary would be to "develop technology for full digital animation and smart devices" and "build the foundation for the production of animation aimed at children and families". It was established in October 2014, with Katsuji Morishita of Production I.G serving as its president.
On November 20, 2018, IG Port announced that the production operations of Xebec would be transferred to Sunrise, citing that the studio's primary business (production for animation and other on-screen works) "has been running a deficit for a long time" and its revenue from licensing business "has not made up for the shortfall." The company finalized the transfer of the studio, with its cost amounting ¥300 million, on April 1, 2019.

Why this record matters
The phrase “japanese stock holder for entertainment media” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q5971072. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007, 2014, 2018 and 2019.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
