Tokyo Metropolitan Police Department
The Metropolitan Police, with a staff of more than 40,000 police officers, and over 2,800 civilian personnel, manages 102 stations in the prefecture.
Metropolitan Transportation Authority Police Department
The department was formed in 1998, with the consolidation of the Long Island Rail Road Police and the Metro-North Railroad Police Departments. Since 9/11, the department has expanded in size and has ramped up dramatically its counter-terrorism capabilities, adding canine teams and emergency services officers. There are 1 lieutenant, 4 sergeants, and 44 police officers who are assigned to the K-9 Unit and serve as handlers with their canine partners. The department now has one of the best trained K-9 units in the United States. At a national competition in 2013, two MTA Police dogs took third and fourth place in explosives detection.
