By Peter B. E. Hill

The Japanese mafia - known collectively as yakuza - has had an extensive influence on Japanese society over the past fifty years. Based on extensive interviews with criminals, police officers, lawyers, journalists, and academics, this is the first academic analysis in English of Japan's criminal syndicates. Peter Hill argues that the essential characteristic of Japan's criminal syndicates is their provision of protection to consumers in Japan's under- and upper-worlds. In this respect they are analogous to the Sicilian Mafia, and the mafias of Russia, Hong Kong and the United States. Although the yakuza's protective mafia role has existed at least since the end of the Second World War, and arguably longer, their sources of income have not remained constant. The yakuza have undergone considerable change in their business activities over the last half-century.
