About Yokosoh Co., LTD.
Yokosoh Co., LTD., Business Division, a for-profit Japanese facilities maintenance contractor headquartered in Yokosuka, Kanagawa Prefecture, provides change of occupancy maintenance, interior and exterior painting, plumbing repairs, and general facility upkeep services to U.S. Navy installations in Japan as a prime contractor on full-and-open federal delivery orders under single-award IDIQ contracts. The vendor competes exclusively without set-aside designations, holding no SBA certifications.
Yokosoh's federal footprint is singularly concentrated on Navy family housing and facility maintenance in Japan. The vendor operates 100% as a prime contractor across 1,807 awards spanning the past several years, with zero subcontract activity. Customer concentration is extreme: the Department of the Navy Installations Command accounts for 1,750 awards (97% of the portfolio) valued at $523.5 million in combined potential value, making Navy facility operations in Japan the vendor's entire federal customer base. The Department of the Navy Naval Facilities Engineering Command placed 18 awards worth $20.6 million, and the Department of Defense Education Activity issued 7 awards valued at $1.7 million; all other customers represent sub-million-dollar exposure. Recent delivery order work includes a $2.844 million change of occupancy maintenance order awarded April 10, 2026, for family housing unit preparation at Commander Fleet Activities Yokosuka, a $964,989 order from December 2025 for the same scope, and a $801,893 order from January 2025, all under firm fixed-price structures.
The vendor's primary parent vehicle is an indefinite-delivery contract (N4008418D0402) awarded by Navy Installations Command on October 25, 2022, with a $44,165,303.15 ceiling running through August 31, 2027, from which 177 task orders have been placed. Two additional large IDIQ vehicles—N4008414D0401 and N4008411D0405—carry 651 and 510 task orders respectively valued at $29.3 million and $28.7 million combined. The portfolio spans maintenance of family housing facilities (1,592 awards, primary PSC), building finishing and painting work (85 and 42 awards), and minor facility repairs across the Kanto Plain region including Commander Fleet Activities Yokosuka and Naval Air Facility Atsugi. Activity was flat to declining over the past five years (2022: 41 awards; 2023: 64; 2024: 36; 2025: 45; 2026 year-to-date: 11), with only three awards (combined potential value $3.2 million) reaching ultimate completion within the next twenty-four months, presenting minimal recompete cliff exposure. Yokosoh performs all contracted work directly with no identified subcontractors, supporting the Navy's housing readiness operations at forward-deployed installations in the Pacific region.
