According to “An Overview of Japanese Police,” an English document by the National Police Agency distributed to foreign police agencies in August 2008, “Boryokudan (yakuza) groups pose an enormous threat to civil affairs and corporate transactions. They are also committing a variety of crime to raise funds by invading the legitimate business community and pretending to be engaged in legitimate business deals. They do this either through companies, etc. which they are involved in managing or in cooperation with other companies.”
