Nintendo Cube Co., Ltd.,[b] formerly NDcube, is a Japanese video game developer and a subsidiary of Nintendo based in Japan with offices in Tokyo and Sapporo.

The company was founded on March 1, 2000, as NDcube, as a joint venture between Nintendo and the biggest advertising firm in Japan called Dentsu, hence the "ND" (Nintendo-Dentsu) in the name.

[3] In 2010, Nintendo decided to buy out the company's shares from Dentsu and the other shareholders, being then the major shareholder on the company, with its changing from 78% to 96% initially, to 97% in 2015, and since 2023, to 99% of the shares.

[4][5][6] Since 2010, many employees from Hudson Soft migrated to a restructured NDcube, which is also head by Hidetoshi Endo, a former president at Hudson Soft that assumed NDcube at the end of the 2000s.

[7] In 2019, the director of the Mario Party series since his Hudson Soft days, Shuichiro Nishiya, became the company's president of the company in the place of Hidetoshi Endo, who was the president of NDcube for almost ten years.
