Japan's Ground Self-Defense Force has held a ceremony to mark the creation of a new command that has control over all GSDF units nationwide.

The Ground Component Command oversees the commands of Japan's 5 regional armies to direct all units in an integrated manner.

The command was set up on March 27th in one of the largest reorganizations of the GSDF since its establishment 64 years ago, in 1954.

The ceremony was held on Wednesday at Asaka Base, which straddles Tokyo and Saitama prefectures.

Defense Minister Itsunori Onodera told the crowd that now more than ever the GSDF needs to be able to respond quickly and flexibly to emergencies on a nationwide level.

The command was launched in response to changes in Japan's security environment. In particular, China's increased maritime activities have heightened the need for more flexible control over GSDF units.

The command has direct control of a new amphibious rapid deployment brigade. The brigade specializes in remote island landings. The command also has a department for coordinating with the US military. It's the first department of its kind set up in the GSDF.

The Commanding General of the Ground Component Command, Lieutenant General Shigeru Kobayashi, says his duty is to use the authority vested in the command to keep the units firmly under civilian control.
