Nintendo Entertainment Analysis & Development (任天堂情報開発本部 Nintendō Jōhō Kaihatsu Honbu), commonly abbreviated as Nintendo EAD, was the primary game development branch of Nintendo, and formerly the largest department branch of Nintendo. Initially founded as Nintendo Research & Development 4 and among the successors to the Nintendo Research & Development Department, the division was headed by Shigeru Miyamoto and is mostly known for developing his intellectual properties.


After Donkey Kong was a success, Hiroshi Yamauchi in 1983 created a new division of Nintendo Research & Development, Nintendo Research & Development 4. The department would mostly focus on Shigeru Miyamoto, who was appointed as chief producer, while Hiroshi Ikeda, former president of Toei Animation, would be made General Manager. Many of Nintendo R&D4's early games were assisted by Gunpei Yokoi's team, Nintendo R&D1, as R&D4 did not have many experienced programmers at the time. However, after Nintendo R&D1 switched focus to the handheld games market by focusing on Game Boy development, R&D4 became Nintendo's main in-house team for home console development, bringing in SRD to assist with programming.

In 1989, Nintendo R&D4 was restructured in response to the growing size of the team. The developer was renamed to Nintendo Entertainment Analysis & Development, and was divided into two teams: the Software Development Department, which was headed by Miyamoto and focused on game development, and the Technology Development Department, which focused on creating new tools for development and was headed by Takao Sawano.

In 2002, Nintendo would open a Nintendo EAD office in Tokyo, the new division headed by Takao Shimizu and focused on acquiring new talent from Japan's capital who were unable or unwilling to travel to Kyoto to apply.

In September of 2003, Nintendo underwent a corporate restructuring, which led to several members of R&D1 and R&D2 being reassigned into EAD. The EAD Software Development Department was also divided into five separate groups, headed by Hideki Konno, Katsuya Eguchi, Eiji Aonuma, Hiroyuki Kimura, and Tadashi Sugiyama respectively. Shigeru Miyamoto was made the General Manager,

In 2013, Katsuya Eguchi was promoted to Department Manager of Nintendo EAD Kyoto, while Hisashi Nogami was promoted to fill his spot. Yoshiaki Koizumi was promoted to Department manager for the Nintendo EAD Tokyo groups. Later, in June 2014, all of Nintendo's Kyoto internal development teams were moved out of the central office and relocated to the new Nintendo Development Center.

On September 16, 2015, Nintendo EAD and Nintendo Software Planning & Development were merged into a single, new division, titled Nintendo Entertainment Planning & Development, following a corporate restructuring.[1]
