[1] Since 2007, Production I.G is a subsidiary of the IG Port holding company, causing a restructuring which led to the second incarnation of the studio being formed.

[6] Since its inception, Production I.G has produced many of Japan's leading creators, including Mamoru Oshii and Kenji Kamiyama.

[7] Production I.G's works have received critical acclaim outside of Japan, with Mamoru Oshii's Ghost in the Shell[a] reaching #1 on the U.S.

[8][9] When pitching the idea for The Matrix to producer Joel Silver, The Wachowskis showed him Ghost in the Shell anime film and told him they wanted to make a similar movie.

[4] It was in the form of an independent Tatsunoko production branch led by the staff who participated in the Tatsunoko-produced TV series Zillion.

Original animation projects that may or may not be successful were particularly difficult to pass, and there were few opportunities for young talent to demonstrate their abilities.

[7][12] After Zillion, he could have disbanded the team, but he sensed that everyone wanted to continue working together with this group, so he started I.G Tatsunoko.

[1][3] The company was formed by merging the Zillion production team and Studio Chime, which was run by Takayuki Goto, who designed its characters, with the cooperation of Kyoto Animation.

[5] Soon after becoming independent, I.G received an offer from Studio Deen to subcontract the production of Mamoru Oshii's Patlabor OVA and the movie, and with these hits, I.G solidified its position in the industry.

[3] However, Ishikawa began to feel dissatisfied with the fact that even though his company, a subcontractor, actually produced the works, it was only credited as a production partner in the end credits, while the name of the main contractor came to the forefront, and he also began to think that the studio would not be able to survive on low-budget subcontract work in the future.

Ishikawa therefore established Ing with the idea of earning income not only from anime production but also from copyrights, and the studio invested in its works.

[1][5] During his time at Tatsunoko Productions, Ishikawa had seen how the company generate revenue through the operation of the copyrights for original works, so he decided to follow suit.

[1] In Japanese anime production, manufacturers which are involved in the manufacturing, sale and distribution of video software, television stations, publishers and advertising agencies form a production committee, and animation studios generally join after the committee is formed.

He approached Kodansha, the publisher of the original Ghost in the Shell manga, and obtained permission to produce three forms of production: an anime TV series, a movie, and a video game.

[5] Ishikawa's decision was successful and brought in a fairly large amount of money for Production I.G, and the studio subsequently expanded its activities.

[3] In the 2004 film Ghost in the Shell 2: Innocence, Ishikawa took a major risk to change the scheme of the Japanese animation business.

[5][13] Ishikawa decided to produce Ghost in the Shell 2: Innocence on the studio's own , rather than relying on the publisher or other companies in Japan.

[13] Ishikawa narrowed down the list of negotiating partners to DreamWorks, Warner Bros., and 20th century Fox, and finally signed a contract with DreamWorks, founded by Steven Spielberg, and succeeded in raising a huge amount of money and securing a promise of worldwide distribution.

[13] On the other hand, advertising and publicity in Japan was entrusted to Toshio Suzuki, a producer at Studio Ghibli.

[Web 4][15] The company co-developed and co-produced the television series IGPX, directed by Mitsuru Hongo, with Cartoon Network in 2005.

[5] This was the result of Ishikawa's focus on creating a business scheme and leaving the animation production site to younger staff and producers, giving priority to their wishes.

[Web 4] In 2010, IG Port acquired an 11.2% stake in Tatsunoko Production and Mitsuhisa Ishikawa became a non-executive director of the company.

[22] In 2017, IG Port created Lingua Franca, an electronic distribution service company, as a wholly owned subsidiary, with Kyohei Shinpuku[c] as its president.
