History (13):
  • 1948/05
    The Scientific Crime Laboratory was established at 2-1, Kasumigaseki, Chiyoda-ku, Tokyo. The laboratory was attached to the Identification Section of the National Headquarters of Rural Police, the predecessor of the present National Police Agency.
  • 1949/08
    The laboratory moved to 6, Sanbancho, Chiyoda-ku, Tokyo.
  • 1952/09
    The laboratory was attached to the Criminal Investigation Bureau of the National Headquarters of Rural Police.
  • 1954/07
    The laboratory was attached to the National Police Agency.
  • 1959/04
    The name of the laboratory was changed to the National Research Institute of Police Science. The laboratory was reorganized into four departments (Department of General Affairs, Department of Scientific Crime Investigation, Department of Crime and Delinquency Prevention, and Department of Traffic).
Purpose of establishment:
The Institute was established as National Research
Institute of Detection Science in May 1948. Based
on the new Constitution and the new Criminal Procedure
Code after the Second World War, respect for human
right and criminal investigations based on evidences
are stressed.
Business overview:
As the central organization of police science in Japan, this
institute is staffed with approximately 100 qualified researchers
who are knowledgeable in police science. They are engaged in
a broad range of analysis, identification and research work that
requires specialized knowledge and skills in biology, medicine,
science, chemistry, pharmacy, physics, agriculture, engineering,
sociology, education, psychology and other disciplines.
The institute has now established both a domestic and international
reputation in the field of police science.

1. Research and Development
Numerous research projects are drawn up every year to cope with
a growing number of crimes and accidents brought about by
diversified social and economic statuses. In accordance with
these projects, a variety of research is undertaken on the
improvement of criminal investigation techniques and the
prevention of crime and juvenile delinquency as well as on the
implementation of countermeasures for traffic accidents,
traffic congestion and pollution. The work of this institute
is inevitably broadening in scope.

2. Analysis and Identification
From a viewpoint of promoting scientific criminal
investigation, the analysis and identification of criminal
evidence has been the fundamental objective of this institute
ever since its establishment. Such analysis and identification
is requested not only by the police organization but also by
the courts and public prosecutor's office. All counterfeit
currencies discovered and firearms and bullets seized in
connection with crimes are exclusively and systematically
analyzed at this institute. In this respect, the institute is
greatly contributing to the arraignment of criminals in courts
of justice.

3. Training
In view of the rapid progress in science and technology, it
is of paramount importance to innovate and standardize the
techniques of scientific criminal investigation based on sound
principles of methodology. For this reason, a series of
training courses in major fields of forensic science is provided
at the Training Center of Forensic Science to all scientists
in prefectural police laboratories nationwide.
The researchers also help local police scientists improve
their techniques by advising them on cases and by hosting
