I am a retired Senior Commissioner of National Police Agency (NPA) of Japan. I joined the NPA in 1986 and retired in 2021 after 35 challenging and rewarding years of service. During the period, I held a number of senior positions, including Director General of NPA’s Tohoku Regional Police Bureau, NPA’s Director of Second Investigative Division (Fraud/Scams, White-Collar Crime and Public Corruption) and Director of Fourth Investigative Division (Japanese Organized Crimes) of Tokyo Metropolitan Police Department, where he supervised numerous criminal investigations and international operations. After leaving the NPA, I was invited to Waseda Institute of the Policy of Social Safety, Waseda University as Research Fellow, where he has been doing research, focusing primarily on countermeasures against fraud/scams and transnational organized crimes.
