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.
Police division
The term has existed since the creation of police forces in the early 19th century. Most police forces were divided into divisions, usually commanded by a Superintendent. These could cover a wide rural area, a substantial town, or a portion of a city, depending on the population (London, for instance, was divided at one point into 67 Metropolitan Police divisions and a further four City of London Police divisions). In 1949, the Metropolitan Police regraded its divisional commanders as Chief Superintendents and most other forces followed suit.
