Nihon Meccs Co.,Ltd.

Nihon Meccs Co., Ltd., a Japan-based for-profit construction and facility maintenance contractor, operates as a prime contractor delivering design-build and design-bid-build infrastructure services to U.S. military installations across the Asia-Pacific region, competing without set-aside designations in the open federal marketplace.

Nihon Meccs operates exclusively as a prime contractor across a portfolio of 413 federal awards with combined potential value of $2.16 billion and $329.1 million in obligated dollars. The company, registered in SAM.gov since November 2003 and based at 3 Chome-6-3 Irifune, Chūō-ku, Tōkyō-to 104-0042, Japan, specializes in facility maintenance, mechanical and electrical system repairs, HVAC installation and replacement, roof work, structural repairs, asbestos abatement, painting, and comprehensive building renovations. Representative recent work includes a $16.9 million delivery order for building 260 barracks repair at Camp Fuji (Marine Corps, February 2026), an $8.66 million HVAC system installation at Camp Fuji (Marine Corps, February 2026), a $6.53 million steam line repair at Naval Air Facility Atsugi (Navy Installations Command, January 2026), a $5.13 million fire protection system replacement at NAF Atsugi (Navy Installations Command, June 2024), and a $5.38 million sewage treatment facility repair at NAF Atsugi (Navy Installations Command, April 2024). The vendor's NAICS concentration centers on commercial and institutional building construction (212 awards), painting and wall covering services (66 awards), and structural exterior contracting (41 awards), with PSC work concentrated in facility repair and alteration across office buildings, family housing, heating and cooling plants, and military-specific infrastructure.

Customer concentration is heavily weighted to Navy operations. The Navy Installations Command leads with 204 awards ($890.2 million potential value), followed by Naval Facilities Engineering Command with 53 awards ($708.4 million), the Marine Corps with 21 awards ($286.7 million), and Pacific Air Forces with 81 awards ($233.5 million). These five customers account for 90% of award count and 99% of potential value. The two Navy entities together represent approximately 78% of combined potential value, anchoring the vendor's business to Navy facility infrastructure across Japan.

Nihon Meccs holds six named parent contract vehicles generating the majority of task order activity. The Design Build MACC Japan AOR 2022-2027 ($250 million ceiling) carries 40 task orders worth $81.2 million in combined potential value and supports design-bid-build and design-build infrastructure projects across Navy, Marine Corps, and Air Force installations throughout Japan. The vendor also holds a $99 million U.S. Naval Air Facility Atsugi Japan Design-Bid-Build MACC (2025-2033, awarded September 2025) as one of approximately five multiple awardees. The Camp Butler and Commander Fleet Activities Okinawa Marine Corps Base Design-Bid-Build MACC ($250 million, June 2024) carries multiple delivery orders for facility work at Camp Hansen, Camp Foster, and Camp Kinser. The Kanto Japan Plains Operation MACC ($250 million, June 2023) and the NAVFAC Far East Mini MACC Kanto Plains ($49 million, March 2025) support facility projects across the Kanto region. The vendor recently received a $50 million multiple-award IDIQ for interior and exterior painting services in Okinawa (Pacific Air Forces, March 2025). Task orders across these vehicles employ firm fixed-price pricing with individual orders ranging from approximately $2,000 to $16.9 million.

Activity has remained relatively stable year over year—20 awards in 2022, 16 in 2023, 25 in 2024, and 24 in 2025—with 11 awards issued in 2026 year-to-date. Twenty-two awards with ultimate completion dates in the next twenty-four months carry combined potential value of $49 million and represent recompete exposure for the vendor, particularly on the expiring Design Build MACC Japan AOR 2022-2027 vehicle (June 2027 terminal date) and mini-MACC vehicles reaching their final options.

The vendor competes exclusively in full-and-open federal procurements with no set-aside designations across its award footprint, positioning it as a standard for-profit commercial contractor rather than a small business or disadvantaged-business holder. Place of performance for all active work is Japan, with administrative oversight by Navy Installations Command, Naval Facilities Engineering Command, Marine Corps, and Pacific Air Forces offices managing facilities in the Japan area of responsibility. The vendor has demonstrated consistent delivery across facility-infrastructure categories serving forward-deployed U.S. military operations in the Pacific theater.
