Nintendo was starting to consolidate its software development for a while prior to new division. In 2013, Nintendo moved all of its Kyoto staff into a single building. With the new president in 2015, there was sweeping reorganization that affected both software and hardware with Nintendo Integrated Research & Development turning into Nintendo Platform Technology Development and Nintendo EAD with Nintendo SPD uniting to form this division. The lack of internally developed games gives vagueness to structure of the new division but, it looks structured similarly to former divisions.
Currently, it is unclear how the leadership is set up in the new division, but most of the leadership of the two earlier divisions seem to remain. Shigeru Miyamoto acts as creative fellow but, he no longer responsible for all of Nintendo's game development with his role being absorb by Shinya Takahashi. Instead, he leads specific projects, not all which is directly tied to gaming. Katsuya Eguchi and Yoshiaki Koizumi are under Takahashi and supervise more directly at their respective sites. Beneath them are producers. Some producers like Yoshio Sakamoto, Kensuke Tanabe and Takashi Tezuka likely have larger jurisdiction. Hisashi Nogami and Eiji Aonuma are considered deputy managers due to having involvement in multiple teams. Hitoshi Yamagami, Toshiharu Izuno, Kosuke Yabuki and Kouichi Kawamoto are known group managers in charge of specific production groups.
