About the company
Nikken Sogyo Co., LTD., a Japan-based for-profit organization headquartered in Tokyo, is a prime contractor providing facilities maintenance, infrastructure sustainment, and environmental remediation services to U.S. military installations throughout the Asia-Pacific region, with the overwhelming majority of work performed in Japan under full-and-open (non-set-aside) delivery orders and indefinite-delivery contracts.
Nikken Sogyo's customer footprint is heavily concentrated within the Department of the Navy. The top five funding agencies account for 96% of recent awards, dominated by the Navy Installations Command (82 awards, $179.4 million combined potential value) and Naval Facilities Engineering Command (189 awards, $90.6 million combined potential value). The two rankings diverge meaningfully: NAVFAC places the highest volume of task orders (189 awards) but Naval Installations Command anchors most of the dollar value ($179.4 million versus $90.6 million), driven by larger single-award maintenance and equipment-replacement contracts. The Department of the Army Medical Command, Pacific Air Forces, and Naval Sea Systems Command round out the active customer set with minimal combined volume. Nikken Sogyo has maintained federal contractor registration since December 2003 and operates 100% as a prime contractor with no subcontract footprint.
Nikken Sogyo's capability portfolio centers on facilities maintenance, sewage and wastewater treatment operations, equipment repair and replacement, environmental remediation including PFAS removal, custodial services, and major repair work at U.S. military installations. Recent representative awards include a $6.04 million delivery order from Navy Installations Command (May 2026) for maintenance of incinerator equipment, calibration weight scales, sewage treatment facilities and sewer lines, paint wastewater treatment systems, and potable water tank cleaning and disinfection at Yokosuka; a $7.51 million delivery order (February 2025) combining equipment repairs and overhaul services at multiple Yokosuka facilities; and a $250 thousand single-award blanket purchase agreement from Pacific Air Forces (April 2025) for PFAS-removal resin supply through April 2028. Category concentration reflects this scope: Facilities Support Services (190 awards), Sewage Treatment Facilities (142 awards), Janitorial Services (14 awards), and Appliance and Machinery Repair (13 awards) comprise the bulk of the portfolio.
Nikken Sogyo's vehicle position concentrates on five Navy indefinite-delivery contracts: N4008420D0402 (49 task orders, $64 million combined potential value), N4008415D0401 (48 task orders, $19.6 million), N4008407D0407 (40 task orders, $25.4 million), N6283602D0206 (63 task orders, $347 thousand), and N6283602D0123 (54 task orders, $44 thousand). These vehicles represent the primary ordering mechanisms for task orders to support recurring maintenance and infrastructure sustainment at Commander Fleet Activities Yokosuka, Camp Zama, and related installations in Japan.
Activity has remained relatively flat at six to ten awards per year across 2022–2026, with combined potential value across all 394 prime awards totaling $306.5 million and $162.6 million obligated (53% of potential value). Nine awards with combined potential value of $21 million face ultimate completion within the next twenty-four months, triggering recompete exposure for those vehicles. Place of performance is Japan across all named work; performance is delivered directly by Nikken Sogyo without identified major subcontractors.
