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.
Chief inspector
From 1933, every Metropolitan Police division had two chief inspectors: chief inspector (administration) and chief inspector (crime) (the latter also being a uniformed administrative officer and not replacing the divisional detective inspector (DDI)). From 1949, sub-divisional inspectors and DDIs were regraded as chief inspectors and current chief inspectors were regraded as superintendents. From 1953, chief inspectors commanding sub-divisions and detective chief inspectors commanding divisional CIDs were regraded as superintendents grade I, other chief inspectors were regraded as superintendents grade II, and a redefined rank of chief inspector was created for senior inspectors. Since 1974, the Metropolitan Police has only had one rank of superintendent, in common with the rest of the country.
