Meccs Mitomo JV

Meccs Mitomo JV, a Japan-based corporate joint venture between Japanese companies Meccs Corporation and Mitomo Corporation, operates as a prime contractor delivering HVAC preventive maintenance and inspection, facilities repair, construction, and infrastructure modernization services at U.S. military installations throughout Japan. The company competes exclusively on a full-and-open basis with no set-aside designations across a portfolio of 142 prime awards carrying $2.12 billion in combined potential value. Meccs Mitomo JV has been registered in SAM.gov since 2013 and maintains headquarters in Tokyo.

The vendor's capability portfolio centers on recurring HVAC maintenance, non-recurring mechanical equipment replacement, building exterior and infrastructure repair, electrical systems work, power distribution upgrades, and design-build or design-bid-build construction projects at forward-deployed military installations. Representative work includes a $3,278,122.34 Navy Installations Command delivery order (March 2026) for preventive maintenance and inspection of HVAC systems at various U.S. locations and Commander Fleet Activities Japan; a $2,526,023.08 Marine Corps order (September 2024) for truck fill stand modernization at Marine Corps Air Station Iwakuni; a $4,254,376.01 Pacific Air Forces order (September 2025) for construction of base resiliency storage at Atsugi Air Base; and a $1,427,274.54 Army Pacific Region order (November 2025) for infrastructure support services at military installations in Honshu. The vendor's work is performed entirely in Japan, with places of performance including Naval Base Yokosuka, Camp Zama, Camp Foster, Marine Corps Air Station Iwakuni, Yokohama North Dock, and Atsugi Air Base.

Customer concentration is dominated by Defense operations in the Pacific region. The Department of the Navy Installations Command leads by award count (70 awards, $78.9 million combined potential value), followed by the Department of the Army Installation Management Command Pacific Region (45 awards, $93.8 million), and the United States Marine Corps (11 awards, $938.7 million). Two top-five customers by dollar value anchor the portfolio: the Department of the Air Force Pacific Air Forces ($994.3 million combined potential value across two awards) and the Marine Corps ($938.7 million across eleven awards). Together these two customers represent the majority of the vendor's total contract ceiling, reflecting Meccs Mitomo JV's strategic role as an infrastructure partner for large construction programs at MCAS Iwakuni and related Pacific installations.

Meccs Mitomo JV holds three prime indefinite delivery contracts with combined value exceeding $770 million. The Navy Installations Command awarded a single-award HVAC maintenance and inspection IDC (April 1, 2025) with a ceiling of $31,029,490.82 and completion through March 31, 2027, requiring OEM and Japanese trade certification for all personnel performing maintenance and repair work. The Marine Corps awarded a $495 million multiple-award design-build and design-bid-build MACC for MCAS Iwakuni (June 30, 2023, extending through June 29, 2031) supporting small-magnitude construction projects with task orders ranging from $3,000 to $25 million. The Marine Corps also holds a $250 million multiple-award mini-MACC at MCAS Iwakuni for small-scale design-build and design-bid-build projects (August 21, 2024, extending through August 20, 2029). Historical vehicle relationships include a $990 million Army indefinite delivery contract for construction at Honshu installations and Yokota Air Base (2015–2020, now expired). Current delivery orders flow primarily through the Navy's Indefinite Delivery Contract N4008420D0409 (56 task orders, $19 million combined potential value), the Army's MACC for Honshu and Yokota facilities (15 task orders, $12 million), and Marine Corps construction vehicles at Iwakuni.

Activity remained flat year-over-year across 2022–2025 (14 to 19 awards annually) before declining to three awards in 2026 year-to-date as of the source snapshot (May 2026); this recent decline reflects the timing of large contract awards and option exercises rather than a structural loss of customer confidence. Seven awards with ultimate completion dates within the next twenty-four months carry combined potential value of $9.6 million, representing moderate recompete exposure on smaller facilities-maintenance task orders. The vendor has zero subcontract footprint in the source data and operates exclusively as a prime contractor, with no sub-award relationships documented. Work is categorized primarily under NAICS codes for building equipment contractors (57 awards), industrial and commercial building construction (63 awards combined), and HVAC contractors (15 awards), with PSC concentration in maintenance of administrative facilities and buildings (64 awards) and office building maintenance (24 awards).
