3. Hiroshi Yamauchi ($2.1 billion)
During his time at Nintendo several classic consoles hit the market, including the much-revered Nintendo Entertainment System, which had some unforgettable games made for it like Super Mario Bros. and Legend of Zelda.
And Nintendo’s wild success in the game industry led to Yamauchi landing a windfall and becoming one of the richest men in Japan, with his personal fortune being valued at a whopping $2 billion US dollars when he passed away in late 2013.
