Tokyo Underworld: The Fast Times and Hard Life of an American Gangster in Japan by Robert Whiting

Through the eyes of Nick Zappetti, a former GI, former black marketer, failed professional wrestler, bungling diamond thief who turned himself into "the Mafia boss of Tokyo and the king of Rappongi," we meet the players and the losers in the high-stakes game of postwar finance, politics, and criminal corruption in which he thrived. Here's the story of the Imperial Hotel diamond robbers, who attempted (and may have accomplished) the biggest heist in Tokyo's history. Here is Rikidozan, the professional wrestler who almost single-handedly revived Japanese pride, but whose own ethnicity had to be kept secret. And here is the story of the intimate relationships shared by Japan's ruling party, its financial combines, its ruthless criminal gangs, the CIA, American Big Business, and perhaps at least one presidential relative. Here is the underside of postwar Japan, which is only now coming to light.
