To compensate, Yakuza groups plunged into financial fraud, stock manipulation, and cybercrime, giving rise to a new generation of gangster-nerds, more interested in business than blackmail. For instance, “Yamaguchi-Gumi,” the largest Yakuza organization in Japan, boasts roughly 36,000 members and associate members, constituting less than a half of the total Yakuza gangsters in Japan, and is estimated to haul in as much as ¥2 trillion ($21 billion) annually.
为了补偿收入，黑帮开始介入金融欺诈，操纵股价或者网络犯罪，并借此培养新一代黑帮成员，而且也比敲诈更加刺激有趣。以日本黑帮最大的派别“山口组”为例，该组织拥有大约3.6万成员，几乎占全国黑帮成员总人数的一半，每年收入高达2万亿日元（折合210亿美元），还拥有数百个附属组织和遍布全国的网络。
