The Fleet Intelligence Command (Japanese: 艦隊情報群, Hepburn: Kantai Jōhō-Gun)^[1] is the intelligence arm of the Japanese Maritime Self-Defense Forces. It was previously known as Intelligence Business Command (情報業務群, Jōhōgyōmugun).

The FIC is commanded by Captain Yosuke Inaba as of 2023.^[2]

It was the only intelligence unit of the Maritime Self-Defense Force, which was organized as an information business group with the establishment of the Defense Intelligence Headquarters on 20 January 1997.

On 19 March 2020, Takashi Inoue, then FIC commander, was reported to have debriefed a former vice admiral on Japanese national security circumstances.^[3] He was subsequently indicted for violating the State Secrecy Law in December 2022.^[4][5]

On 1 October 2020, the Information Business Group was abolished and the Fleet Intelligence Command was established in its place. The Operation Information Support Corps, Electronic Information Support Corps, and Basic Information Support Corps were abolished, and the Operation Information Corps and Electromagnetic Information Corps were newly added.^[6][7] The FIC's capacity has been increased from about 200 to about 230, the efficiency of operations has been improved by integrating the units, the ability to collect and analyze electromagnetic wave information, etc. has been improved, and the information support function for the Self-Defense Fleet has been added.^[8][9]

On 25 and 26 August 2022, FIC conducted a tabletop exercise with the U.S. Navy Task Force 70 (TF70) / Carrier Strike Group 5 at the Maritime Operations Center in Funakoshi.^[10]

On September 9, 2024, the JMSDF announced that the Fleet Information Warfare command will be formed, which will integrate the FIC alongside the Oceanography ASW Support Command, Guard Post and the Communications Command.^[11]

The main task is to analyze and distribute operational information necessary for units such as the Self-Defense Fleet and the Regional District Forces that operate ships and aircraft.

The headquarters is located in the Maritime Operations Center in Funakoshi district.^[12][13][6]
