Sora Ltd. (有限会社ソラ, Sora Company Limited) is a Japanese video game developer founded by former HAL Laboratory employee Masahiro Sakurai. It was formed in the years following Sakurai's resignation from his position at HAL Laboratory. Although it is considered a video game developer, it is merely used by Sakurai to conduct business with other companies, and therefore outsources development on its games to other developers. Its only employees are Sakurai and his wife, Michiko.
For a while, Sakurai ran Project Sora, a division of Sora Ltd. and Nintendo, which was started in January 2009. An important distinction between Sora Ltd. and Project Sora is that the former is not officially affiliated with Nintendo; Project Sora allowed Sakurai to use Nintendo's resources for game development. It only developed Kid Icarus: Uprising for the Nintendo 3DS before officially closing on June 30, 2012.
Sora Ltd.'s next game, Super Smash Bros. 4, co-developed by Bandai Namco, was released for the Nintendo 3DS under the name Super Smash Bros. for Nintendo 3DS in Japan on September 13, 2014, and on October 3, 2014 in North America and Europe, as well as releasing on the Wii U under the name Super Smash Bros. for Wii U on December 6, 2014 in Japan, on November 21, 2014 in North America, and on November 28, 2014 in Europe.
