The 1st Helicopter Brigade (Japanese: 第1ヘリコプター団, Dai-ichi Herikoputa-Dan) is based at JGSDF Camp Kisarazu in Kisarazu, in Chiba Prefecture.[1] Formerly an independent brigade, it was attached to the Central Readiness Force on March 28, 2007.[2] Like most JGSDF units, the brigade's aircraft are deployed to conduct exercises from their Kisarazu base annually during the New Year period.[3]
Prior to the brigade's integration into the CRF, it had been actively involved in civil disaster operations in response to natural disasters such as wildfire, earthquakes, and flood.[6]
History
The 1st Helicopter Brigade was first established on March 20, 1959, by the Japan Ground Self-Defense Force Aviation School at JGSDF Camp Kasumigaura in Kasumigaura, Ibaraki. After the brigade was established, two helicopter companies were created on March 1, 1968, during a period of reorganization.[7]
The 1st Helicopter Company was stationed at JGSDF Camp Kisarazu on March 22, 1968, with the 2nd Helicopter Company arriving on June 1, 1968. A special transport squad was established in the brigade on December 19, 1986. Another period of reorganization began on March 27, 2006, when a communications and reconnaissance squad was added to the unit. On March 28, 2007, the 1st Helicopter Brigade was formally incorporated into the Central Readiness Force.[2]
The brigade was deployed by the Central Readiness Force on its first operation to subdue wildfires in the forests of the Yamanashi Prefecture on April 29, 2007.[8] They have been also deployed on humanitarian operations, specifically in the aftermath of the March 2011 earthquake.[6]
On March 26, 2020, the 1HB has established an aviation corp to manage V-22 Ospreys for the ARDB.[9] The Ospreys are due to be deployed to Kisarazu with plans to be deployed at Saga Airport in the future. One CH-47J helicopter squadron is to be at JGSDF Vice Camp Takayubaru.[10]
