The Cabinet Intelligence and Research Office (内閣情報調査室, Naikaku Jōhō Chōsashitsu),[3] Naichō (内調), is an intelligence agency of Japan, an agency of the Cabinet Secretariat, which reports directly to the Prime Minister.

The agency is said to be an equal to the American Central Intelligence Agency.[4] However, it is often criticized as being rather ineffectual, spending most of its energy translating foreign publications rather than gathering any substantial intelligence,[5] while being accused of spying on Japanese nationals on domestic soil.[5]

Like most intelligence agencies in Japan, its personnel are usually recruited from other agencies.[6] Around 100 out of 170 CIRO agents are from other agencies/ministries with top positions occupied by career police officers.[7]


The CIRO was created by the Allied Forces through the formation of the Research Office[2] on April 1952 with Jun Murai as the first director in an attempt to replicate its structure after the CIA.[7] But due to widespread opposition, this plan was discarded.[7] The RO was placed under jurisdiction of the Prime Minister's office in 1957 and was known as the Cabinet Research Office.[1] The CRO was later renamed as the CIRO in 1986.[1]

The Cabinet Intensive Information Center was established on April 11, 1996 to ensure that the CIRO can inform the Prime Minister in case of severe emergencies.[4] It's located in the Prime Minister's residence.[4]

In August 2007, discussions of intelligence reforms through the paper Improvement of Counter-Intelligence Functions resulted in the establishment of the Counterintelligence Center.[8]

Since 2015, CIRO agents are usually recruited to be sent to the International Counter-Terrorism Intelligence Collection Unit.[9][10]

Spy scandal[edit]

On January 17, 2008, an official of Naichō was charged for spying for Russians, passing them classified information. The Russians denied the claim.[11] Since then, there had been calls for greater accountability on Naichō.[12]


Naichō headquarters occupies 6th floor of the Cabinet Office Building

According to its official web site, organization of Naichō is as follows:[13]

  • Director of Cabinet Intelligence (内閣情報官)
  • Deputy Director of Cabinet Intelligence (次長)
  • Divisions
    • General Affairs Division (総務部門)

The CIRO is headquartered in Chiyoda, Tokyo, in a building called "H20".[14]

It was established in 2001 and has 320 personnel employed with at least 100 of them being imagery intelligence analysts.[7]
