The story
The company was founded on March 1, 2000, as Nd Cube, as a joint venture between Nintendo and the biggest advertising firm in Japan called Dentsu, hence the "ND" (Nintendo-Dentsu) in the (original) name. Nintendo had 78% of the shares of the company at the time, while 13.3% of the shares were owned by Dentsu and the rest of the 8.7% were owned by other shareholders.
In the years after Mario Party 8's 2007 release, many employees from Hudson Soft migrated to Nd Cube, including former Hudson Soft president Hidetoshi Endo, who became president of Nd Cube around 2009.
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.
In 2012, Nd Cube rebranded to NDcube. In the same year, the company released Mario Party 9 for the Wii—the company's first Mario Party game.
In 2019, the director of the Mario Party series from Mario Party 6 to Super Mario Party, Shuichiro Nishiya, replaced Hidetoshi Endo as the company's president. Endo had served as president of NDcube for almost ten years.
In 2024, NDcube rebranded to Nintendo Cube.
