HSI assists Tokyo Police arrest 2 men attempting to smuggle weapons from the US

TOKYO – U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) special agents provided investigative leads to the National Police Agency of Japan (NPA) resulting in the Sept. 26 arrest of two Japanese nationals and the seizure of a firearm.

Daisuke Nagasaka, 39, and Koji Shimizu, 41, both of Nakamura-kita, Nerima-ku, Tokyo, were arrested by the Tokyo Metropolitan Police Department (TMPD) on charges in violation of Japanese law for illegal importation of firearms.

Nagasaka and Shimizu are charged with conspiring to import an automatic handgun and 100 rounds of ammunition from the United States. They are alleged to have shipped  the handgun and 100 rounds of ammunition Sept. 11 in airmail packages from a U.S. post office destined to Daisuke Nagasaka in Tokyo.

HSI special agents intercepted the purported weapon and seized the packages before their departure from the United States. The handgun was replaced with a fake handgun and a controlled delivery to Japan ensued.

The TMPD initiated an investigation after they received information provided by HSI through the NPA.

HSI continues this ongoing investigation on the smuggling of weapons from the United States.

HSI’s Office of International Affairs (OIA) is responsible for enhancing national security by conducting and coordinating international investigations. With agents in 75 offices in 48 countries around the world, OIA represents ICE’s broadest footprint beyond our borders. HSI attaché offices work with foreign counterparts to identify and combat transnational criminal organizations before they threaten the United States.
