All units have been deployed to the Ground Self-Defense Force's amphibious task force, which is responsible for the defense of remote islands. A commemorative ceremony was held on the 24th in response to the new deployment of the third regiment, which plays the core role of the unit, to Takematsu Garrison in Nagasaki Prefecture.

As a result, the amphibious force has completed all planned deployments, leaving it with approximately 3,300 personnel. A response system will be built, and deterrence and response capabilities will be further strengthened, Defense Minister Kihara said.
