Here’s an informative post from the Japan Subculture Research Center (@japansubculture). The US has declared war (not in the military sense) on the yakuza, one of four transnational criminal organizations singled out by the POTUS in the EXECUTIVE ORDER: BLOCKING PROPERTY OF TRANSNATIONAL CRIMINAL ORGANIZATIONS:
On July 24th, President Barak Obama declared war on the yakuza (ヤクザ）aka The Japanese mafia, in an executive order which stated that “(the yakuza) are becoming increasingly sophisticated and dangerous to the United States; they are increasingly entrenched in the operations of foreign governments and the international financial system, thereby weakening democratic institutions, degrading the rule of law, and undermining economic markets. These organizations facilitate and aggravate violent civil conflicts and increasingly facilitate the activities of other dangerous persons. I therefore determine that significant transnational criminal organizations constitute an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States, and hereby declare a national emergency to deal with that threat.”
