About Nippon Bldg.care LIMITED
Nippon Bldg.care LIMITED, a Tokyo-based Japanese for-profit corporation, operates as a prime contractor providing facility maintenance, repair, and construction services to U.S. military and diplomatic installations throughout Japan on a full-and-open competitive basis with no set-aside designations. The company has maintained registration in the System for Award Management since November 2003 and competes exclusively as a prime contractor — 100% of 179 recent awards are prime contracts or IDCs, with zero subcontract work.
The company's capability portfolio centers on building systems maintenance and repair work. Representative prime work includes a $538,234.27 firm fixed-price contract from the Department of Defense Pacific Region (awarded August 2023, completion July 2028) for elevator inspection, maintenance, and repair across four installations (Camp Zama, Sagamihara Housing Area, Sagami General Depot, and Akasaka Press Center); a $432,817.59 definitive contract from the Department of State's Bureau of Overseas Building Operations (awarded October 2025, completion February 2027) for replacement of HVAC chilled and hot water piping and thermal insulation at the Mitsui Housing Compound in Tokyo; and a $358,449.61 definitive contract from the Bureau of Overseas Building Operations (awarded June 2022, completion February 2023) for laundry room and balcony restoration services. Additional recent scope includes bathroom restoration, automatic door inspection and maintenance, water heater replacement, cooling tower inspection and water quality control, NOx converter repair, roof and balcony restoration, pipe repair and insulation, and groundwater microbiology analysis.
Customer concentration is pronounced and geographically clustered. The top five agencies account for 91% of recent awards and are dominated by State Department facilities and Army and Air Force installations in Japan. The Department of State's Bureau of Overseas Building Operations leads with 68 awards and $6 million combined potential value, followed by the Department of the Air Force's Pacific Air Forces with 31 awards and $5.7 million, and the Department of the Army's Installation Management Command Pacific Region with 29 awards and $3.7 million. The Department of State's Bureau of East Asian and Pacific Affairs contributes 23 awards at $653 thousand. The two rankings track closely — dollar concentration follows award volume — with no material tension between high-order and high-dollar customers.
Nippon Bldg.care LIMITED holds three active single-award indefinite-delivery contracts (IDCs) that anchor its federal work. A $1,443,625 IDC from Pacific Air Forces (awarded April 2026, completion March 2031) covers inspection and maintenance of elevators and escalators at Yokota Air Base and Tama Annex. A $250,000 IDC from Pacific Air Forces (awarded August 2025, completion July 2033) covers inspection and maintenance of automatic opening doors at the same locations. A $245,000 IDC from the Bureau of Overseas Building Operations (awarded May 2023, completion April 2026) covers bathroom restoration services under US Embassy Tokyo. Beyond these, the company places task orders against unnamed indefinite-delivery vehicles (F6256201D9004, SJA80016D0021, 19JA8023D0010, and others), collectively accounting for 50 task orders across the portfolio.
Activity shows year-to-year volatility. After seven awards in 2022 and six in 2023, the company awarded five in 2024, then rebounded to eleven in 2025, with two task orders through early 2026. The combined potential value across all 179 awards sits at $17.1 million, with combined dollars obligated at $17.4 million (101% of potential value), indicating mature, executed work. Five awards with ultimate completion dates falling within the next twenty-four months carry combined potential value of $813 thousand and will face recompete risk. All work is performed at U.S. installations in Japan; place of performance never deviates from Japan.
The vendor has no subcontractor relationships recorded in the award portfolio — all 179 awards are executed as prime contracts. The category concentration reflects the facility-maintenance posture: the top NAICS codes are Other Services to Buildings and Dwellings (33 awards), Other Personal and Household Goods Repair and Maintenance (21 awards), and All Other Specialty Trade Contractors (13 awards). Top PSC codes are Housekeeping—Carpet Laying/Cleaning (25 awards), Maintenance/Repair/Rebuild of Equipment—Plumbing, Heating, and Waste Disposal Equipment (22 awards), and Maintenance of Family Housing Facilities (16 awards). The vendor's geographic isolation to Japan and exclusive focus on U.S. government facility operations at military bases and diplomatic posts constrains competitive relevance to U.S. domestic federal contractors, but positions it as a specialized regional partner for overseas facility management.
