Soaring Wii sales boosted the net worth of Nintendo founder Hiroshi Yamauchi by $3 billion last year, according to a new Forbes list of the richest people in Japan.
The 80-year-old gaming magnate rose to first place, up from third, on the list with an estimated fortune of $7.8 billion, according to this Reuters report.
Yamauchi became a principal owner of the Mariners in 1992 but sold his stake in 2004 to Redmond-based Nintendo of America.
He still owns 10 percent of Nintendo, the shares of which have tripled since the Wii’s launch.
(No wonder Steve Jobs is looking into a Wii-like remote that could make the Apple TV into a game console….)
