Mitomo Marutaka JV

Mitomo Marutaka JV, a for-profit corporate joint venture headquartered in Okinawa, Japan, provides construction, facilities maintenance, and base operations support services to the U.S. Department of Defense as a prime contractor across 259 awards with no subcontract footprint. The vendor competes on a full-and-open basis without set-aside designations, operating two major indefinite-delivery, indefinite-quantity (IDIQ) contracts anchoring its federal presence across Pacific region military installations.

Mitomo Marutaka JV's core capability portfolio centers on facilities-related work: HVAC equipment replacement and maintenance, emergency generator and electrical system repair, water utility infrastructure (pumps, meters, storage tanks, piping), roofing and structural repairs, asbestos and lead-based paint abatement and sampling, specialized construction (fuel tank replacement, sewage systems, building interior refurbishment), and base operations support services. Representative prime work includes a $533 thousand HVAC replacement order for Camp Shields and White Beach in Okinawa (Navy Installations Command, delivery order, FY 2024); a $2.73 million roof repair at Hario Housing in Japan (Department of Defense Education Activity, delivery order, FY 2022); a $428.8 thousand Bush Medical and Dental Clinic HVAC and ventilation system refurbishment at Camp Courtney, Okinawa (Marine Corps, delivery order under Mini MACC, FY 2023); and a $1.04 million interior recoating and repair of drinking water storage tanks at Camp Shields (Naval Facilities Engineering Command, delivery order, FY 2022).

Customer concentration is extreme and Navy-anchored. The Department of the Navy Installations Command accounts for 139 awards (54% of volume, $151 million combined potential value), and the Department of the Navy Naval Facilities Engineering Command holds 57 awards (22% of volume, $106.1 million combined potential value). Together, Navy funding sources represent approximately 76% of all awards and 79% of combined potential value. The Department of the Air Force Pacific Air Forces, United States Marine Corps, and Department of the Army Installation Management Command Pacific Region round out the active customer set at 22, 23, and 9 awards respectively, covering the remaining 21% of awards and 18% of potential value. This concentration reflects Mitomo Marutaka JV's role as the dominant prime contractor for U.S. military facilities maintenance and construction in Okinawa and subordinate Pacific installations.

Mitomo Marutaka JV operates under five named parent IDIQ vehicles, with task-order distribution spanning Indefinite Delivery Contract N4008411D0065 (75 task orders, $10.2 million), Indefinite Delivery Contract N4008416D0014 (51 task orders, $23 million), Indefinite Delivery Contract N4008421D0055 (49 task orders, $16.1 million), the Mini Multiple Award Construction Contract for Various Government Installations in Okinawa, Japan (29 task orders, $8.6 million), and Indefinite Delivery Contract FA527009D0018 (27 task orders, $9.2 million). The vendor also holds the Okinawa Base Operations Support (BOSC) contract, a five-year $38.9 million IDIQ with four one-year options awarded by Navy Installations Command in November 2020, which generates blanket task orders and option-year funding vehicles across the portfolio.

Activity trajectory shows moderate variability over recent years: 15 awards in 2021, 16 in 2022, 24 in 2023, 19 in 2024, and one award in 2026 as of the source date. Combined potential value across all 259 awards totals $289.7 million, with $78.5 million (27%) obligated. Recompete exposure in the next twenty-four months is minimal—only one award with combined potential value of $252 thousand completes in that window, indicating stable contract positions with most awards carrying out to 2025 and beyond. Work is performed in Japan, primarily at Okinawa military installations including Camp Foster, Camp Shields, White Beach, Kadena Air Base, and Marine Corps Air Station Futenma, with subordinate performance at Sasebo Naval Base and other forward-deployed locations.
