OYO Corporation, Pacific

OYO Corporation, Pacific, a foreign-owned environmental engineering firm headquartered in Okinawa, Japan, operates exclusively as a prime contractor on full-and-open federal contracts supporting U.S. military installations throughout Japan, delivering environmental compliance, hazardous waste management, water quality surveillance, natural resource surveys, and archaeological site inspection services to Navy, Army Corps of Engineers, Marine Corps, and Air Force customers.

OYO delivers concrete environmental and remediation services grounded in a $25 million Naval Facilities Engineering Command Indefinite Delivery Contract (N4008423D0087, extending through December 14, 2030) that anchors nearly 80% of the vendor's combined potential value. Representative prime delivery orders under this vehicle include applied habitat enhancement at Awase Communication Station ($400,976, September 2025), natural resources surveys for Commander Fleet Activities Okinawa ($344,257, March 2025), habitat enhancement and monitoring at Naval Air Facility Atsugi ($394,247, May 2024), perfluorooctane sulfonate and perfluorooctanoic acid contaminated waste disposal at Yokosuka ($367,675, March 2023), and archaeological site inspections at Commander Fleet Activities Sasebo ($256,059, February 2024). OYO also executes task orders under smaller Army Corps of Engineers and Pacific Air Forces vehicles, including drinking water surveillance across Marine Corps bases in Okinawa and Camp Fuji (multiple awards totaling over $900 thousand combined), cultural resources surveys at Kadena Air Base ($81,139, January 2024), and asbestos-containing material sampling and disposal services ($58,585 and $22,135, respectively). All work is performed in Japan where OYO maintains local operational and regulatory compliance capabilities.

Customer concentration is dominated by the Navy's environmental compliance footprint. Naval Facilities Engineering Command places seven awards carrying $25.9 million combined potential value—representing 79% of OYO's total potential value across the entire portfolio. The Army Corps of Engineers Engineering District Japan (ENDIST Japan) follows with 29 awards but only $5.1 million combined potential value, reflecting smaller individual task order sizes. Navy Installations Command, Pacific Air Forces, and the Marine Corps account for the remaining $1.6 million combined. The two customer-concentration rankings diverge sharply: ENDIST Japan leads by award count (29 of 50 total awards, 58%) but ranks second by dollars, while Naval Facilities Engineering Command places far fewer orders (7 awards, 14% of total) but anchors the majority of contract value through the $25 million IDIQ.

Activity has declined from a 2023 peak of nine awards to two awarded in 2026 year-to-date. Nine awards with combined potential value of $1.5 million reach ultimate completion within the next twenty-four months, creating near-term recompete exposure concentrated in the Navy's environmental and Army Corps of Engineers SOFA acquisition programs. OYO subcontracts in a minor footprint (4 of 50 awards, 8% by count), delivering geotechnical survey and engineering services to HDR Engineering, HDR Wtna JV, Louis Berger Kyowa JV, and Reid Middleton on military construction and infrastructure projects in Japan. The vendor's work spans Environmental Consulting Services (32 awards), Engineering Services (10 awards), and specialized environmental assessment and water quality analysis categories, with no socioeconomic set-aside participation across the entire portfolio.
