117 - Investigative Division One

【捜査一課、sousa-ikka】

To be more precise, it is named the "First Investigative Division of the Criminal Investigation Bureau".

To begin with, the First Investigative Division is part of the Criminal Investigation Bureau of the Metropolitan Police Department, which has three other sections: the Second, Third, and Fourth Investigative Divisions.

The First Section is in charge of cases involving human life.

The Second Section handles cases involving white-collar crimes. White-collar crimes range from electoral violations and bribery cases to fraud and embezzlement.

The Third Section is responsible for larceny crimes. This section is responsible for burglaries, robberies, and other thefts that do not involve human life. Incidentally, the Third Section also handles the counterfeiting of banknotes.

The Fourth Section is commonly known as the "yakuza group". This division works with the Organized Crime Countermeasures Division, established to accompany the recent Act on Prevention of Unjust Acts by Organized Crime Group Members, to crack down on crimes committed by organized crime groups.


The First Investigative Division is the largest of these four divisions. First of all, it is in charge of investigating violent crimes. This section is responsible for investigations involving human life, such as homicides and assaults. The Division is, furthermore, divided into ten units.

First Investigative Division, Unit One. This Unit manages so-called general affairs, uninvolved with actual investigations. It is the section that allocates investigative expenses.

Unit Two. This one is responsible for ongoing investigations and follows up on cases that have "gone cold" and been closed.

The other eight units, numbered 3 to 10, investigate homicides. The generally accepted term "Investigative Section One" likely refers to Units Three through Ten.


In addition, there is a Larceny Investigative Unit that investigates robberies and other crimes such as assaults, assaults, and rapes; an Arson Investigative Section that investigates arson and other fire-related crimes; and a Special Crimes Investigative Unit that investigates other crimes such as kidnappings, confinement, extortion, blackmail, and hijackings.
