Yokosan Kogyo K.K.

Yokosan Kogyo K.K., a Japan-based for-profit corporation headquartered in Yokosuka, Kanagawa, supplies portable sanitation equipment rental and maintenance services to the U.S. Department of the Navy as a prime contractor, operating exclusively in the open market with no set-aside designations across its federal footprint. The vendor has maintained a registered federal contractor status since November 2006 and competes on firm fixed-price purchase orders without SBA certifications or minority-business designations.

Yokosan Kogyo K.K.'s capability portfolio centers on the rental, delivery, and maintenance of temporary toilet and handwash station equipment to support naval operations and shipboard personnel in the Pacific region. Representative work includes a $51,303.39 purchase order from Naval Sea Systems Command (awarded January 22, 2024, completed August 16, 2024) for temporary toilet and wash-stand supply and maintenance aboard ship; a $40,668.44 order from Naval Sea Systems Command (awarded May 6, 2024) for temporary toilet and handwash station rental services; and a $25,801.36 order from Naval Sea Systems Command (awarded August 27, 2024) for portable sanitation facilities supporting Pacific fleet readiness. All work is performed in Japan and involves commercial portable sanitation services tailored to temporary facility requirements.

Customer concentration is heavily skewed toward the Department of the Navy. Naval Sea Systems Command accounts for 66 awards and $1.4 million in combined potential value across the vendor's 142-award footprint; the U.S. Pacific Fleet Forces holds 26 awards worth $220 thousand; and Navy Installations Command carries 43 awards valued at $176 thousand. These three Navy sub-agencies represent 97% of recent award volume. Yokosan Kogyo K.K. places task orders under two indefinite delivery contracts: N6264907A0147 (61 task orders, $608 thousand combined potential value) and N6264902A0002 (26 task orders, $43 thousand combined potential value), both issued by the Navy.

Activity has contracted over the past five years — four awards in 2022, two in 2023, five in 2024, two in 2025, and one in 2026 to date — with combined potential value across all 142 awards totaling $7.4 million and only $2 million in dollars obligated to date (27% drawdown). The vendor's award portfolio spans solid-waste landfill operations (63 awards), septic tank and related services (50 awards), and general equipment rental (27 awards) under NAICS categories, with PSC coding dominated by lease or rental of plumbing and waste-disposal equipment (65 awards). The vendor operates exclusively as a prime; it has not subcontracted to other federal primes and carries no sub-award activity in the source data.
