A Japanese man born to wealthy parents grew up in poverty after being given to another couple in a hospital six decades ago, while the infant who took his place went to live a privileged life of private tutoring, university and is today head of a property firm.
The 60-year-old man - who has declined to give his name - was raised reliant on hand-outs from the state after the man he thought was his father died when he was just two. The woman he considered his mother had to support his three older brothers and there were few comforts in their one-room apartment as he grew up.
