Kokusai Unyu K.K.

Kokusai Unyu K.K., a Japan-based international transportation company, provides commercial trucking and logistics services to the U.S. military in Japan as a prime contractor under a $500 million indefinite-delivery, indefinite-quantity contract and associated blanket purchase agreements, operating on a full-and-open (non-set-aside) basis.

The company is a for-profit organization headquartered in Nagasaki, Japan, with continuous System for Award Management registration since August 2005. Kokusai Unyu K.K. operates exclusively in the freight trucking and transportation space, centered on NAICS 484110 (General Freight Trucking, Long-Distance, Truckload) and 484120 (General Freight Trucking, Long-Distance, Less Than Truckload), with PSC coding in motor freight transportation. The vendor's capability footprint spans general goods movement, sensitive-item transport, and hazardous-materials handling across U.S. military installations in Japan, including Fleet Activities Yokosuka, Marine Corps Air Station Iwakuni, Naval Supply Facilities Atsugi and Yokota, and Naval Munitions Command Pacific Area Coordination Eastern Area Division in Sasebo.

The vendor's customer base concentrates heavily within the Department of Defense footprint in Japan. The Defense Logistics Agency Distribution anchors 6 awards carrying $500 million in combined potential value—the entirety of which derives from the Japan Commercial Trucking Services Solicitation master IDIQ awarded September 30, 2021, with ultimate completion September 30, 2026. The Department of the Army Materiel Command Sustainment Command, Department of the Navy Naval Air Systems Command, U.S. Pacific Fleet Forces, U.S. Marine Corps, and Department of the Navy collectively account for the remaining awards across smaller task orders and blanket purchase agreements, with combined potential values ranging from $52 thousand to $2.9 million. The vendor's vehicle position includes 25 delivery orders against the Japan Commercial Trucking Services Solicitation IDIQ, 13 task orders under Blanket Purchase Agreement FA520917A0026, and 10 task orders under Blanket Purchase Agreement FA520914A0008.

Activity has accelerated sharply in the most recent two years: 3 awards in 2021, 1 in 2023, 2 in 2024, 7 in 2025, and 14 as of March 2026. The vendor holds $503.7 million in combined potential value across 54 total awards, though only $3.2 million (1% of potential value) has been obligated to date, reflecting the indefinite-delivery structure and the small monthly task-order values typical of routine military logistics operations. Representative delivery orders include monthly transportation services to USARJ G4 logistics operations ($2,239.28, March 2026), Marine Corps Air Station Iwakuni Defense Mapping Office support ($30,830, October 2025), Naval Supply Facility Yokota operations ($39,391, October 2025), and USS Ronald Reagan general trucking between Iwakuni and Yokosuka ($9,916.40, May 2024; $12,934.43, November 2023). All awards carry firm fixed-price terms with performance in Japan and no set-aside designation, indicating competition against other vendors on the same master IDIQ.
