How far can reality TV go to engage viewers? Back in the 1990s, a hugely popular variety show in Japan featured a 22-year-old aspiring comedian having to survive solely on magazine sweepstakes, alone and naked in a small room for 15 months. His ordeal was recently revived in the British documentary film "The Contestant". In this edition, Nasubi reflects on the disturbing TV show and shares his thoughts on today's social media craze, with FRANCE 24's Yuka Royer.
