Forbes.com has declared former Nintendo chairman Hiroshi Yamauchi is the wealthiest man in Japan.
Yamauchi retired from the company in 2005 after 55 years of service, remaining a major shareholder. His net worth has more than tripled since and now stands at USD 7.8 billion. The 80 year-old's net income rose by 48 per cent last year to reach USD 2.5 billion.
According to Forbes, this is all down to "booming sales of the Wii gaming device". Either that or he's really got into car boot sales and eBay since he retired.
