Japanese Special Operations

Japanese Special Operations Group (SOG)

&nbsp &nbsp

The Japanese Special Operations Group (特殊作戦群 Tokushu Sakusen Gun) is the Japanese Ground Self-Defense Force’s counter-terrorist unit established by the former Japanese Defense Agency to counter terrorist activities and deter guerrilla-style attacks on Japanese soil and to conduct military operations, like the 1st Airborne Brigade, against guerrillas or enemy commandos. The unit is based in Narashino, Chiba garrison in Funabashi, Chiba with the 1st Airborne Brigade. They are currently known more recently as the Special Forces Group.

The SOG has been referred to as Japan’s Delta Force, due to their specialized role in the Japanese Ground Self-Defense Force. Delta Force personnel had been responsible for assisting the Japanese Ground Self-Defense Force in raising the SOG’s foundations prior to its establishment.

The civilian counterpart of the SOG is the Japanese National Police Agency’s Special Assault Team.


In 1998, the Japanese Defense Agency had proposed the formation of a unit in the JGSDF that would handle tasks such as Counter-terrorism with a selected group of JGSDF soldiers from the 1st Airborne Brigade sent to the United States to be trained by Delta Force operators. At the same time, two platoons were created from the brigade as a means of creating the unit’s foundations. These consist of the G Platoon (Formation Unit) and the S Platoon (Research Unit).

The establishment of unit’s framework had been completed in 2003, after 3 years of training and organization.

On March 27, 2004, the Japanese Defense Agency had activated the unit as the Special Operations Group with the mandate under the JGSDF as its Counter-terrorist unit.

In 2005, the SOG had deployed four of its operators to serve as bodyguards for the Japanese commander of the Japanese Ground Self-Defense Force’s contingent in Iraq under the Japanese Iraq Reconstruction and Support Group.

On March 28, 2007, the SOG had merged with the 1st Airborne Brigade, the 1st Helicopter Brigade and the 101st NBC Protection Unit to create the Central Readiness Force.

The unit had changed its name on March 26, 2008 from the SOG to the SFGp or the Special Forces Group.
