Nd Cube Co., Ltd. (Japanese: エヌディーキューブ株式会社 Enudī Kyūbu Kabushiki Gaisha), stylized NDcube, 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. Nd Cube has offices in Tokyo and Sapporo. Nd Cube is responsible for developing the most recent Mario Party games starting with Mario Party 9.
By April 2006, many of Nd Cube'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 Nd Cube.
As of June 2019, the former president Hidetoshi Endo resigned, and the company's chief creative director Shuichiro Nishiya was promoted to the president.
