Kanagawa Nabco Pty. LTD.

Kanagawa Nabco Pty. LTD. Construction Division, a Japanese construction and engineering company based in Yokohama, operates as a prime contractor delivering facilities maintenance, repair, construction, and infrastructure upgrade services to U.S. Department of Defense installations throughout Japan. The company is a for-profit corporate entity with no SBA small-business or socioeconomic designations and competes exclusively in full-and-open procurements; all 536 awards in the source represent prime contracts or IDIQs with no subcontract footprint.

Kanagawa Nabco's federal capability portfolio centers on mechanical systems maintenance (HVAC, heating and cooling systems, compressors, valves, air handling units), automatic and roll-up door repair and replacement, vertical transportation equipment (elevators, service lifts) maintenance, plumbing and water distribution system work, electrical system upgrades, roofing repair and replacement, facility demolition and asbestos abatement, and discrete construction projects at forward-deployed installations. The company's work is geographically concentrated at U.S. military installations in the Kanto Plains region of Japan—primarily Naval Air Facility Atsugi, Camp Zama, Camp Fuji, and Yokohama-area facilities—where it maintains specialized familiarity with Japanese Ministry of Land, Infrastructure and Transport licensing requirements and local operational conditions that domestic contractors find difficult to replicate. Recent representative awards include a $1.7 million road repair contract at Naval Air Facility Atsugi (August 2025, firm fixed-price, completion December 2026); a $1.87 million galley facility renovation including hazardous material abatement (July 2025, firm fixed-price, completion October 2026); a $1,027,397.50 access apron repair at NAF Atsugi (August 2025, firm fixed-price, completion May 2027); and a $1,055,822.41 electrical distribution line repair at Camp Zama (June 2023, completion November 2024).

Customer concentration is acute and singularly defined. The Department of the Navy Installations Command accounts for 327 awards carrying $330.1 million in combined potential value—61% of the total award count and 23% of the combined potential value across all customers. The Department of the Navy Naval Facilities Engineering Command places 97 awards worth $108.3 million. The Department of the Air Force Pacific Air Forces anchors the remaining bulk of potential value through a single $990 million multiple-award construction contract (MACC) for U.S. Army and Air Force installations in Honshu and Yokota Air Base that runs through 2030. Together, Navy and Naval Facilities Engineering represent 423 of 536 awards (79%) and drive day-to-day operational revenue; Air Force's single vehicle represents 68% of combined potential value but generates task order flow incrementally. The Army Installation Management Command Pacific Region, the Marine Corps, and the Office of Personnel Management account for the remaining volume.

Kanagawa Nabco holds four substantial single-award IDIQs with Navy Installations Command and Naval Facilities Engineering Command totaling $40.1 million in ceiling value. A $26.05 million single-award contract (awarded April 2024, completion March 2032) covers maintenance and operation of HVAC systems, hangars, and storage tanks at Naval Air Facility Atsugi, with recurring-work funding orders issued annually; a $5.3 million vehicle (awarded February 2023, completion March 2031) provides vertical transportation equipment, automatic door, and mechanical systems maintenance at NAF Atsugi and surrounding U.S. Forces Japan controlled areas; a $4.77 million contract (awarded April 2022, completion March 2027) supports non-recurring preventive maintenance and installation of automatic and sliding doors across Japan installations; and a $99 million multiple-award Design-Bid-Build construction contract (awarded September 2025, completion September 2033) enables discrete construction project delivery at Naval Air Facility Atsugi. The company also holds significant positions on Naval Facilities Engineering Command's Kanto Plains Mini MACC ($49 million, awarded March 2025, completion March 2030) and the Air Force's $990 million Army MACC vehicle. Across the top five parent vehicles, Kanagawa Nabco has placed 214 task orders with combined potential value of approximately $54 million.

Activity has remained steady, with 21 to 31 awards per calendar year over the past five years; 2026 shows only seven awards in three months to date, consistent with a typical quarterly pace. Fifteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $10.8 million, representing moderate recompete exposure concentrated in recurring-work funding orders at Naval Air Facility Atsugi and scattered Navy Installations Command delivery orders. The source shows no subcontract activity; Kanagawa Nabco operates exclusively as prime contractor. Work is performed entirely in Japan, with place of performance ranging across Naval Air Facility Atsugi, Yokohama-area naval facilities, Camp Zama, Camp Fuji, and subordinate U.S. Forces Japan controlled areas in the Kanto Plains. The company is registered in the System for Award Management with current registration through August 2026.
