Marine Corps have been shuttling equipment and supplies to Yonaguni Island, Japan, located about 70 miles from Taiwan. This activity is part of broader efforts to establish Yonaguni as a focal point within the First Island Chain strategy.
Over the past two months, shipments of medical supplies and disaster response equipment have moved to and from Kubura Port on Yonaguni Island. Barge movements to the island began as a proof-of-concept for the 12th Littoral Logistics Battalion, which deployed field training equipment to support Resolute Dragon 2025 missions. Initial exercises included combat casualty evacuation and first aid as key elements of Resolute Dragon in Japan’s southwest islands.
The deployment supported by Yonaguni included shipping containers, refrigeration equipment, and water. Supplies were offloaded to the island and transferred to the Japan Self-Defense Force’s Camp Yonaguni. In total, eighteen 20-foot ISO containers, two SIXCONs (water containers), and a 40-foot refrigeration container were offloaded over two days (September 15–16). The containers were returned to Naha Military Port by September 19.
“The back-and-forth shipments of medical supplies and disaster response equipment comes at an increasing pace as the Corps aims to make Yonaguni Island a focal point in its First Island Chain strategy.”
Yonaguni Island’s proximity to Taiwan makes it a strategically significant location for U.S. and allied forces in countering potential contingencies in the Western Pacific. The island’s role in logistics, contingencies planning, and disaster response exercises aligns with ongoing efforts to enhance distributed operations in the region.
US Marines are expanding logistics and training presence on Yonaguni to bolster a potential outpost near Taiwan under the First Island Chain framework, emphasizing rapid logistics and medical/disaster-response readiness with formal drills tied to Resolute Dragon 2025.
