About the company
Clean Service Co., LTD, a Japanese subsidiary of Clean Service Company LIMITED, operates as a prime contractor providing facilities maintenance, wastewater treatment system cleaning, and kitchen exhaust ventilation system cleaning services to the U.S. Navy at military installations in Japan. The vendor competes in full-and-open procurements with no set-aside designations across 50 recent awards totaling $22.9 million in combined potential value.
Clean Service Co., LTD's customer concentration is tightly focused on the Department of the Navy across multiple commands. Department of the Navy Installations Command leads by potential value at $15.9 million across 17 awards, while Naval Facilities Engineering Command generates the highest award count at 22 awards worth $3.2 million combined. The United States Marine Corps accounts for 6 awards valued at $3 million. These three customers represent 94% of the vendor's recent award count and 100% of its combined potential value. The revenue rankings diverge meaningfully—Installations Command's larger dollar value per award reflects bigger delivery orders against recurring IDCs, while Facilities Engineering Command's higher award count reflects more frequent smaller task orders. Navy Bureau of Medicine and Surgery, Defense Commissary Agency, and Naval Sea Systems Command account for the remaining volume.
Clean Service Co., LTD holds two active single-award indefinite delivery contracts: a Navy Installations Command IDC (N4008424B0409) awarded December 19, 2024, with a $3.16 million ceiling running through January 31, 2030, for preventive maintenance and cleaning services at Commander Fleet Activities Yokosuka; and a Marine Corps IDC awarded April 1, 2022, with a $2.47 million ceiling through March 31, 2030, for wastewater treatment and kitchen exhaust ventilation system cleaning at Naval Air Facility Atsugi and Combined Arms Training Center Camp Fuji. Five additional parent IDCs carry smaller remaining capacity. Representative delivery orders include a $622,148.90 Navy Installations Command order issued January 30, 2026, for preventive maintenance, repair, cleaning, and disposal services at Commander Fleet Activities Yokosuka through January 31, 2027; a $357,865.85 Marine Corps order issued March 26, 2026, for the fourth option period of recurring wastewater and exhaust ventilation cleaning at Atsugi and Camp Fuji through March 31, 2027; and a $348,580.19 Naval Facilities Engineering Command order issued March 19, 2025, for the third option period of recurring services at the same locations, modified to increase service frequency at Building 1460.
All work is performed at U.S. Navy and Marine Corps installations in Japan. The vendor's capability portfolio concentrates on facilities support services (26 awards), commercial and industrial machinery repair and maintenance (7 awards), and nonhazardous waste treatment and disposal (6 awards), with Housekeeping–Facilities Operations Support as the dominant PSC category (27 awards). Activity has averaged roughly 2.4 awards per year over the past five years—relatively flat with light 2025 and 2026 volume. Only two awards face ultimate completion within the next twenty-four months, carrying combined potential value of $980 thousand, presenting minimal near-term recompete exposure. Clean Service Co., LTD operates exclusively as a prime; it holds no subcontract awards in the source data.
