Sunsoft is the video game division of Sun Electronics Corporation (Sun Denshi), a Japanese company founded in 1971.

In 1978, Sun Electronics began producing UsefulNotes/{{Arcade Game}}s. The company never became a major player in the arcades, though Sunsoft continued sporadically to develop arcade games into the 1990s.

In 1985, Sun Electronics began releasing games for the [[UsefulNotes/NintendoEntertainmentSystem Nintendo Family Computer]] under the Sunsoft label. A few years later, the company began to distribute NES games in the U.S. through Sun Corporation of America. In 1988, Sunsoft formed a partnership with Tokai Engineering (TEC); exactly what this partnership contributed to Sunsoft's games is not clear, but this coincided with a dramatic improvement in their quality. Sunsoft also became heavily interested in producing {{Licensed Game}}s and console ports of computer games.

The changing economics of video game development were not kind to Sunsoft. In 1995, the company escaped bankruptcy, selling off a few games to be released by Creator/{{Acclaim}}. A more serious decline became evident around 2001, when its international distribution channels closed. What saved Sunsoft from extinction was the advent of online game services; as well as making many of their older games available on Nintendo's UsefulNotes/VirtualConsole, Sunsoft has released a small number of original downloadable games.
