Nichibei United Corporation

Nichibei United Corporation, a foreign-owned for-profit corporation headquartered in Okinawa, Japan, provides parts washer equipment rental, maintenance, and environmental remediation services to the U.S. Marine Corps and other Department of Defense components at military installations throughout Japan as a prime contractor on 99% of recent awards, competing full-and-open with no set-aside designations.

The vendor's customer base is heavily concentrated in Japan-based military operations. The U.S. Marine Corps accounts for 74 awards carrying $21.7 million in combined potential value — representing 100% concentration of both award count and dollar value across the top five federal customers. The remaining customer set comprises the Department of the Army Corps of Engineers Engineering District Japan (4 awards, $1.1 million), the Department of the Navy (2 awards, $91 thousand), the Department of the Navy Naval Construction Forces (2 awards, $17 thousand), and the Department of the Air Force Pacific Air Forces (1 award). This concentration reflects Nichibei's position as a specialized local service provider embedded in the Marine Corps' maintenance and environmental management supply chain in the region.

Nichibei's capability portfolio is dominated by parts washer equipment rental and bioremediation services. The vendor holds a single-award indefinite delivery contract with the Marine Corps (contract M6740023D0004, $2,360,652.97 ceiling, running through May 11, 2028) that authorizes task orders between $10,000 and $120,000 for equipment rental and maintenance across Marine Corps installations. Recent representative delivery orders include a $15.65 million order for parts washer rental and maintenance at Marine Corps installations in Japan (awarded July 20, 2026, completing July 19, 2027), a $309,918.25 order for Marine Expeditionary Force equipment rental (awarded July 20, 2025), and a $102,217.89 order for 3rd Division parts washer support (awarded June 12, 2024). The vendor also performs environmental remediation and recycling support through the Status of Forces Agreement acquisition program — a $339,993.90 order for FY25 recycling program support at Kadena Air Base was awarded May 2, 2025, extending through May 1, 2028.

Activity has contracted substantially. Awards per year declined from eight in 2023 to three in 2026, and only five awards (combined potential value $16.1 million) complete within the next twenty-four months, presenting limited near-term recompete exposure. Nichibei placed task orders under two primary IDC vehicles: the M6740023D0004 contract (19 task orders, $16.8 million combined potential value) and an earlier contract M6740007D0004 (51 task orders, $1.2 million combined potential value), reflecting a transition between Marine Corps IDC awards. The vendor carries a single subcontract as a sub to Amentum Services, Inc., on a hazardous materials metal can manufacturing task (awarded September 11, 2024), but operates almost entirely in prime capacity.

Top NAICS codes cluster around All Other Miscellaneous Waste Management Services (54 awards) and Other Commercial and Industrial Machinery and Equipment Rental and Leasing (20 awards), aligned with parts washer rental and environmental remediation work. The vendor's award history spans from 2005 through July 2026, though recent-year volume (three awards in 2026, five in 2025) signals possible transition or consolidation of Marine Corps ordering under fewer, larger task orders rather than the granular delivery-order cadence of prior years.
