BBC business editor Simon Jack and journalist Zing Tsjeng tell the tale of the billionaire who founded the conglomerate SoftBank and was once, very briefly, the richest person in the world. As the child of Korean immigrants in Japan, Son’s childhood took in sharing a home with pigs, an obsession with the businessman who brought McDonald’s to Japan, and a move to study in the USA aged 16.

The podcast that tells tales of titans of technology, Wall Street moguls, pop stars, sporting legends, CEOs and entrepreneurs also explain how Son overcame a diagnosis that meant he was once given just two years to live. Then Simon and Zing decide if Son is good, bad, or just another billionaire.
