Named after one of the most prominent video game developers working under Konami, Hideo Kojima, Kojima Productions is the result of Konami merging several promising subsidiaries, one of which was Kojimas own development team who were formerly working at Konami Computer Entertainment Japan.
A big aspect of Kojima Productions birth was the workload of it's namesake. As the Vice President of KCEJ, Kojima often found himself bogged down with administrative responsibilities and buissness management of the company which enforced major restrictions upon his ability to focus upon games under his development. Taking control over his own Production company allowed Kojima to focus extensively upon the games themselves and allowing him much freedom in terms of how he approaches his work.
Technically, Kojima Productions has been a squad of designers led by Kojima ever since 1987, although it was only in 2005 that there was any official title given to the group which came about after the aforementioned merging. Although Kojima Productions is a self serving company, they still often rely upon Konami as a publisher.
In 2005, Kojima Productions had approximately 100 working staff, but with the development of Metal Gear Solid 4, the number steadily doubled to 200.
Konami Productions is located in Roppongi Hills in Roppongi, Tokyo and it's logo is the FOX badge from Metal Gear Solid 3, a game released shortly before the merger was announced.
As of April 1st 2015, Kojima Productions is no longer called that by name as it was folded into Konami proper as part of a company-wide restructuring.
