About Kobakyu, K.K.

Kobakyu, K.K., a Japan-based sole proprietorship, provides oil and water separator maintenance, pump out, cleaning, and grease trap services to U.S. military installations in Okinawa and the broader Asia-Pacific region exclusively as a prime contractor, with no subcontracting footprint. The company operates under NAICS 491220 (Hazardous Waste Treatment and Disposal) and related PSC codes for equipment maintenance and waste facility operations, competing on full-and-open, firm fixed-price delivery orders with no set-aside designations across the Department of Defense and related agencies.

Kobakyu's customer concentration is narrow and geographic. The Department of the Air Force's Pacific Air Forces accounts for 17 of 22 awards and $3.5 million of the combined $4.9 million potential value (71% by count, 71% by dollars). The Department of the Army Installation Management Command Pacific Region holds four awards ($1.1 million), and the United States Marine Corps holds one award ($259 thousand); these three customers represent 100% of recent contract activity. Work spans two primary indefinite delivery vehicles: a $1.8 million single-award Indefinite Delivery Contract (FA527022D0002) running through June 22, 2027, which anchors 13 task orders worth $1.1 million combined, and a $499,999 single-award Blanket Purchase Agreement for grease trap maintenance at Kadena Air Base expiring September 30, 2026. Representative delivery orders include a $330,796.84 Defense Logistics Agency purchase order for pump out and cleaning services at Chimuwan, Kuwae, and White Beach Tank Farms (ultimate completion September 30, 2029), a $325,225.15 Pacific Air Forces task order for oil and water separator maintenance issued August 2022, and a $140,058.09 PACAF delivery order for pump out and inspection services at Kadena Air Base and Okuma Resort awarded April 2024.

Activity has grown modestly — one award in 2021 to six in 2025 — though the portfolio remains small. Only one award (combined potential value $42 thousand) reaches ultimate completion within the next twenty-four months, limiting near-term recompete exposure. Kobakyu has been registered in the System for Award Management since April 2011 and holds a consistent niche in environmental compliance and facilities maintenance exclusively at forward-deployed U.S. military installations in Japan, with all awards structured as firm fixed-price delivery orders. The company obligated $2.1 million across awards (43% of combined potential value), indicating steady but partial drawdown on vehicle capacity.
