NDcube

, formerly Nd Cube Co., Ltd., is a Japanese video game developer and subsidiary of Nintendo. Originally founded on March 1, 2000, through a joint venture between Nintendo and advertising firm Dentsu (the "Nd" in the name reflecting this), the company was bought out by Nintendo in 2010 and is now a fully owned subsidiary of Nintendo. NDcube has offices in Tokyo and Sapporo. NDcube is responsible for developing the most recent Mario Party games starting with Mario Party 9, although its first developed game since becoming a subsidiary of Nintendo is .

By April 2006, many of NDcube's employees at the time had moved to other companies, including Nintendo and Square Enix. At a later point, however, several previous employees of Hudson Soft, and Nintendo-Hudson joint venture Monegi Inc., moved to the company, including various staff that had worked on the Hudson-developed Mario Party games, including former president Hidetoshi Endo, who became the president of NDcube.

As of June 2019, the former president Hidetoshi Endo resigned, and the company's chief creative director Shuichiro Nishiya was promoted to the president.
