Nintendo Software Planning & Development

Nintendo Software Planning & Development, often shortened to Nintendo SPD, is a division of Nintendo that focuses on research, planning, and development. Shinya Takahashi is the deputy general manager of Nintendo SPD. The division itself is divided into four groups, labeled Group No.1, Group No.2, Group No.3, and Group No.4. Nintendo SPD was created shortly after Nintendo disolved two of its other teams, Nintendo R&D1 and Nintendo R&D2. Several former staff members from R&D1, R&D2, and Nintendo EAD made up a large amount of the division's members, though there were many newcomers to the group. Nintendo SPD performs many tasks; it either works independently on small, oftentimes unique, games, helping the development of a game alongside another team, or manages the production of first-party franchises.

Group No.1
Led by Yoshio Sakamoto, Group No. 1 was responsible for developing most of the titles for the WarioWare series and all of the titles for the Rhythm Heaven series.

Group No.2
Managed by Hitoshi Yamagami, Group No.2 worked on some of the titles in the Brain Age series as well as other standalone titles, mostly for handheld systems.

Group No.3
Managed by Kensuke Tanabe, Group No.3 has developed quite a few of the Mario spin-off series, including the Mario Strikers games and the Mario vs. Donkey Kong games. Its main purpose is to assist the development of coproductions with western developers.

Group No.4
Led by Hiroshi Sato, Group No.4 worked on some of the later games in some Mario franchises, including Mario Party and Donkey Kong.
