Wako Service Co.,Ltd.

Wako Service Co.,Ltd., a Japanese for-profit organization based in Shiroi, Chiba, provides oil water separator cleaning and waste oil recycling services to the U.S. Air Force at overseas installations as a prime contractor under full-and-open (non-set-aside) delivery orders. The vendor operates exclusively through a single-award indefinite-delivery contract (FA520923D0003) issued by Pacific Air Forces with a ceiling value of $9.191 million and a performance period extending through February 29, 2032.

Wako's customer concentration is absolute: all 13 awards in the source data—100% of combined potential value—derive from the Department of the Air Force's Pacific Air Forces command. The vendor's work is geographically and functionally narrow. All delivery orders execute at Yokota Air Base and Tama Service Annex in Japan and carry identical scope: cleaning of oil water separators and recycling of waste oil in accordance with Japanese environmental standards (JEGS), applicable laws, commercial standards, and the performance work statement. Wako provides all necessary personnel, supervision, equipment, tools, materials, vehicles, and services to perform this environmental maintenance work. The top NAICS category is Materials Recovery Facilities (11 awards), with the remainder coded to Environmental Consulting Services and Custodial Janitorial; the primary PSC code is Housekeeping-Waste Treatment/Storage.

Activity is episodic but consistent: the vendor received one award in 2017, then three in 2023 (the year the current IDC was awarded), one in 2024, and two each in 2025 and 2026. Combined potential value across all awards sits at $13.3 million, with $4.6 million obligated to date (35% draw). Recent delivery orders include a $260,965.23 order awarded March 1, 2026, with completion by February 28, 2027; a $245,240.08 order awarded March 1, 2025, with completion by February 28, 2026; and a $262,330.57 order awarded March 1, 2024, with completion by February 28, 2025. The vendor faces minimal near-term recompete exposure: only one award (combined potential value $261 thousand) reaches ultimate completion within the next twenty-four months. Wako holds no subcontract work and operates no other IDVs, GWACs, BPAs, or agency-wide vehicles. The relationship is transactional and geographically confined to a single Air Force installation complex in Japan.
