About this Unit
The **Military Traffic Management Command (MTMC) Yokohama** was a key U.S. Army logistics and transportation unit based in Yokohama, Japan, primarily active during the post-World War II and Cold War periods. Established to support U.S. military operations in the Pacific, MTMC Yokohama managed the movement of personnel, equipment, and supplies through the vital port facilities of Yokohama. The unit played a crucial role during the Korean and Vietnam Wars, coordinating large-scale transportation efforts to sustain U.S. and allied forces. Over the years, MTMC Yokohama adapted to evolving mission requirements and technological advances until its functions were eventually consolidated under the U.S. Army’s Surface Deployment and Distribution Command (SDDC).
