Kouan

Japan has several domestic intelligence and public security agencies. Two of these [law enforcement](/wiki/Law_enforcement "Law enforcement") [organizations](/wiki/Category:Organizations "Category:Organizations") have appeared in the anime and manga *[Detective Conan](/wiki/Detective_Conan "Detective Conan")*:
* [Security Bureau of the National Police Agency](/wiki/National_Police_Agency#Security_Bureau "National Police Agency")
* [Tokyo Metropolitan Police Department Public Security Bureau](/wiki/Tokyo_Metropolitan_Police#Public_Security_Bureau "Tokyo Metropolitan Police")
Both have similar roles supervising public security and work closely together. The National Police Agency (NPA) focuses on the national scale and its security bureau (NPA SB) supervises the police security departments in all prefectures except Tokyo prefecture. The Tokyo Metropolitan Police Department Public Security Bureau (Tokyo MPD PSB) supervises public security in the Tokyo prefecture.
## Trivia[[edit](/wiki/index.php?title=Japanese_Intelligence_Agencies&action=edit&section=1 "Edit section: Trivia")]
* **Public Security Police** (公安警察 ,*Kō'an Keisatsu*[?](/wiki/Help:Japanese "Help:Japanese"))[](#cite_note-1), also called **"Kō'an"** (公安) by some, is a common term used to refer to all the police forces and agents whose mission is to maintain public security in Japan, covering from the NPA Security Bureau, to the Tokyo MPD Public Security Bureau, and to other prefectural security bureaus and departments.[](#cite_note-2) This is the reason why both [Rei Furuya](/wiki/Rei_Furuya "Rei Furuya") and [Hiromitsu Morofushi](/wiki/Hiromitsu_Morofushi "Hiromitsu Morofushi") are generally called *Kō'an Keisatsu/Kō'an*, despite technically hailing from separate organizations.
* Public security agents train at the same police academy as ordinary metropolitan police officers.[](#cite_note-3)
