This is the amazing story of Yoshiaki Tsutsumi (tsoo-TSOO-mee)- who for 4 years solid from 1987-1990 was ranked the richest person in the world, the most powerful and probably revered business person in Japan throughout the 70’s and 80’s. And yet for all his wealth and power, there is very little known about him- but what we do know his rise and very public fall- because there is a big fall, make for a fascinating story- it’s a cracking episode - enjoy
