How old is Yoshiaki Tsutsumi?

Yoshiaki Tsutsumi is a Japanese businessman. During the Japanese economic bubble, Forbes listed Tsutsumi as the wealthiest person in the world during 1987–94 due to his extensive real estate investments through the Seibu Corporation, which he controlled. In 1987, he had a net worth of $20 billion. However, as a result of a series of scandals and his 2005 arrest, his wealth fell to such an extent that he was taken off the Forbes list of billionaires in 2007.
