The 10th Support Group was constituted in the Regular Army on October 15, 1987, at Torii Station, Okinawa, Japan, to provide administrative, base and contingency support.
On March 11, 2011, a devastating magnitude 9.0 earthquake struck eastern Japan followed by a devastating tsunami. It was the largest earthquake in Japan’s history. More than 12,000 people were killed, 16,000 missing, and thousands were displaced. Immediately, Operation Tomodachi was established to provide humanitarian logistics support. At Sendai International Airport more than 120 Soldiers from the 10th Support Group along with other Japan-based Army units, deployed to assist the Japan Ground Self-Defense Force in their relief efforts. The Soldiers provided critical support to reopen the airport and local schools. They also distributed water, clothing and blankets as well as backpacks and toys to children. For its efforts, the unit was awarded the Army Superior Unit Award.
On October 1, 2011, the unit was reorganized and redesignated the 10th Support Group (Regional) and continues to provide administrative control for all Army organizations on Okinawa as well as providing base support and contingency support to deployed/employed forces in the Asia-Pacific region.
