The National Police Agency is prepared to mobilize its special counterterrorism unit in the event that U.S. facilities and other designated locations in Japan come under threat of terrorist attack, NPA officials said Wednesday. Should concrete information about a potential attack become known, the Special Assault Team will be mobilized and placed on alert, according to the officials.

The 200-member SAT has its headquarters in Tokyo and units at NPA regional head offices in Hokkaido as well as Osaka, Kanagawa, Chiba, Aichi and Fukuoka prefectures.

The NPA has already beefed up security at some 350 locations nationwide following last month's terror attacks in the United States.
