ENDIST Japan

The Department of the Army Corps of Engineers Engineering District Japan is a sub-agency of the U.S. Army Corps of Engineers that procures military construction, facility renovation, infrastructure maintenance, and environmental services at U.S. military installations throughout Japan. The district operates under civilian contracting procedures and sources work primarily from Japan-based contractors under bilateral acquisition agreements.

The district has awarded 2,993 federal contracts cumulatively since October 2000, with combined potential value of $5.25 billion and $5.25 billion obligated. Recent award activity totaled 96 in 2022, 101 in 2023, 81 in 2024, 75 in 2025, and 39 year-to-date in 2026. All 395 distinct prime contractors awarded across the portfolio have competed under open competition with no set-asides; 10 awards have carried small-business designations while 2,983 carry no set-aside.

Competitive concentration among recent prime contractors is fragmented. Over the last five years, Environmental Science Corporation leads by award count with 30 awards totaling $7.6 million combined potential value, followed by American Engineering Corporation at 20 awards and $59.4 million and Design Partners, Incorporated at 11 awards and $11.5 million. By potential value, Nippo Corporation dominates with 10 awards worth $509.4 million, while American Engineering Corporation ranks second at $59.4 million. Top-five primes by award count account for 20 percent of recent awards; by potential value, top-five account for 12 percent of combined potential value.

Recent contract opportunities reflect heavy construction activity across Japanese military bases. The Vehicle Maintenance Shop solicitation at Kadena Air Base (W912HV27RA001, due February 16, 2027) is a design-bid-build RFP estimated between ¥15 billion and ¥30 billion for a 36,000-square-foot facility with associated storage and support buildings. The district posted a prequalification notice for FY27 family housing renovation (W912HV27BA001) at Camp Zama covering a nine-story 68-unit tower requiring seismic retrofitting, HVAC replacement, electrical systems modernization, and hazardous materials abatement, estimated between ¥10 billion and ¥25 billion. Maintenance and repair solicitation W912HV26QA013 (due October 28, 2026) covers refrigeration and HVAC systems at two commissaries; amendment 0001 revised evaluation factors and quotation content following RFI responses. A bulk fuel storage tank solicitation (W912HV26RA009, due January 25, 2027) covers construction of a 100,000-barrel JP-8 storage tank at Yokota Air Base with pump house, control systems, and product recovery infrastructure. The district also issued a special notice (W912HV27Z0001, due September 30, 2027) projecting FY2027–FY2028 projects for planning purposes and solicited sources for construction site security monitoring (W912HV-26-Z-0021) at the AFSOC Hotel project at Yokota, limited to U.S. contractors with appropriate security clearance.

All opportunities are restricted to local sources licensed to perform construction work in Japan, and all competitors must register in the System for Award Management database. Recent activity shows sustained mid-scale construction and renovation work across Kadena, Yokota, Camp Zama, and Yokohama installations.
