Hiroshi Yamauchi, the Japanese businessman credited with transforming Nintendo into a world-leading video games company, has died aged 85.
Mr Yamauchi ran the firm for 53 years, and was its second-largest shareholder at the time of his death.
The company confirmed the news in an emailed statement.
A spokesman said the firm was in mourning over the "loss of the former Nintendo president Mr Hiroshi Yamauchi, who sadly passed away this morning."
He died of pneumonia at a hospital in central Japan, the company said, adding that a funeral will take place on Sunday.
Mr Yamauchi ran the company from 1949 until 2002.
In that time, he took what was a small-time collectable trading card company and built it into one of the most recognisable - and successful - video games brands today.
"Hiroshi Yamauchi transformed a run-of the-mill trading card company into an entertainment empire in video games," said Ian Livingstone, co-founder of Games Workshop and former chairman of publisher Eidos.
"He understood the social value of play, and economic potential of electronic gaming. Most importantly he steered Nintendo on its own course and was unconcerned by the actions of his competitors. He was a true visionary."
Rob Crossley, associate editor of Computer and Video Games magazine, told the BBC: "You cannot overestimate the influence the man had on the games industry."
"He spearheaded Nintendo as they moved into the arcade business, with hits such as Donkey Kong.
"This man was the president of Nintendo during the NES, the SNES, the N64 and the Gamecube - the first two were transformative pieces of electronic entertainment."
