On September 30, 2003, as a result of a corporate restructure Nintendo was undergoing, in which several members of the Nintendo R&D1 and R&D2 were reassigned under Nintendo EAD, the department was consolidated into a division and began welcoming a new class of managers and producers. Hideki Konno, Katsuya Eguchi, Eiji Aonuma, Hiroyuki Kimura, and Tadashi Sugiyama were appointed project managers of their own groups within the Software Development Department; Shimizu was appointed project manager of the Tokyo Software Development Department, and Keizo Ota and Yasunari Nishida were appointed project managers of their own groups in the Technology Development Department.
In 2013,
Katsuya Eguchi was promoted Department Manager of both Software Development Departments in Kyoto and Tokyo. As such, he left his role as Group Manager of ''Software Development Group No. 2'', and was replaced by
Hisashi Nogami. On June 18, 2014, the EAD Kyoto branch was moved from the Nintendo Central Office to the ''Nintendo Development Center'' in Kyoto. The building housed more than 1100 developers from all of Nintendo's internal research and development divisions, which included the Nintendo EAD,

, Japan, in the Nintendo Tokyo Office.
In 2003, twenty members of the Entertainment Analysis & Development Division in Kyoto volunteered to relocate to Nintendo's Tokyo Office to expand development resources. These twenty volunteers were primarily from the Super Mario Sunshine team. Management saw it as a good opportunity to expand and recruit several developers who were more comfortable living in Tokyo than relocating to Kyoto.
Takao Shimizu (original manager and producer) and
Yoshiaki Koizumi (director) began hiring several recruits in Tokyo coming from several established companies like SEGA, Koei, and Square-Enix. Shimizu and Koizumi jointly spearheaded their first project, ''Donkey Kong Jungle Beat''. This was followed in 2007 by the release of the critically and commercially acclaimed ''Super Mario Galaxy''. After the release of ''Super Mario Galaxy'', Koizumi was promoted to manager and producer and officially opened Tokyo Software Development Group No. 2.
The Tokyo group had veteran game developer
Katsuya Eguchi as its general manager, who also oversaw development operations for the Kyoto Software Development Department.
