Japan has the lowest crime rate in the developed world. Yet organised crime, controUed by the Yakuza, Japan's gangsters, operates on a bigger scale than the US Mafia, and permeates every facet of the Japanese economy.
Are they a necessary evil? How does Japan accommodate this criminal warp in the fabric of such a closely woven society?
Philip Short , BBC Tokyo correspondent, investigates the place of crime in Japan.
