From gambling rackets and ritualised killings, to the forbidden pleasures of 'soapland', Adelstein's unlikely friendship with the 'Tsunami' gains him unprecedented access to the Yakuza - now under threat after years of tacit acceptance from Japanese society. But in a culture that prizes loyalty and honour above all else, how far can they go in their quest for truth about Tokyo's criminal underworld?
