Aichi Prefectural Police

Its origins date back to 1871 (Meiji 4), when its predecessor organisation, the Aichi Division of Police was founded. The Aichi Division of Police was under the control of the Police Bureau of the Empire of Japan's Home Ministry from 1873 to 1947, when the Diet of Japan passed the Police Act 1947 during Allied occupation. After this, the newly organised National Rural Police took over policing the Aichi prefecture. After further reform of the Police Act in 1954, local police forces were organised by prefecture and made independent under the monitoring and guidance of the National Police Agency, and the current Aichi Prefectural Police was created. Further centralization efforts led to the merging of the Nagoya City Police in to the Aichi Prefectural Police in July 1955.

Uniquely, the Aichi Prefectural Police operated a prefecture-wide fingerprinting scheme from 1955 to 1970. Aichi was the only prefecture in Japan to do so. Under the scheme, all school leavers were required to give all ten of their fingerprints to the police. The purpose of collecting fingerprint data was officially to assist in identifying accident victims. During the program, there were over 2 million prints registered. However, in 1970, after an unidentified body was found in the neighboring Nagano prefecture, it was discovered that Nagano's police force had been given access to Aichi's fingerprint data. Privacy concerns were raised at the prefectural assembly, and the scheme was abolished as a result.

The Aichi Prefectural Police is under the command of a Senior Commissioner and reports directly to the Aichi Prefectural Public Safety Commission.

In 2005, with the opening of Chubu Centrair International Airport in Tokoname and the Aichi Expo 2005, the English 'POLICE' marking was added to the sides of police vehicles to make it clear to foreigners that it is a police vehicle. (The Kagoshima Prefectural Police did this first in 1999. After that, it spread to the Tokyo Metropolitan Police Department, Chiba, Kanagawa, Yamanashi, Shizuoka, Kyoto, Tokushima, Hiroshima, Fukuoka, and Okinawa Prefectural Police Departments).

On 17 May 2007, a member of the Aichi Prefectural Police Special Assault Team was killed in Nagakute after a man took his ex-wife hostage. During the 29 hour standoff, the police lieutenant was shot in the neck while approaching the perpetrator when a dog barked, alerting him to the lieutenant's presence. According to the investigation report, it would be another five hours before he could be rescued, and by then, he could no longer be saved. The report recommended that bulletproof vests be more widely provided and that better sniper support be given in such situations.
