CLEAN SERVICE CO., LTD

CLEAN SERVICE CO., LTD specializes in the maintenance and cleaning of critical wastewater treatment systems and kitchen exhaust ventilation infrastructure at U.S. military installations in Japan. Their core capabilities center on recurring industrial sanitation services, including grease trap cleaning, ductwork decontamination, oil-water separator maintenance, and comprehensive hygiene protocols for high-volume culinary and sewage systems. The contractor demonstrates deep technical proficiency in compliance-driven environmental services, applying standardized preventive maintenance routines to meet Department of Defense hygiene and operational continuity standards. Their work ensures regulatory adherence to ANSI/ASHRAE and EPA guidelines for airborne particulate and grease accumulation control, with a focus on minimizing downtime and preventing system failures in mission-critical facilities. The company maintains a consistent, long-term relationship with the Department of Defense, delivering mission-critical sanitation services across multiple naval and Army installations in Japan, including NAF Atsugi and Camp Fuji. Their engagements are characterized by multi-year, option-based task orders that emphasize reliability, recurring service delivery, and rapid response to operational demands in austere environments. Their primary industry focus lies in nonhazardous waste treatment and disposal (NAICS 562219), alongside specialized miscellaneous waste management services (NAICS 562998) and building maintenance (NAICS 561790). This positions them as a niche provider of facility hygiene services within military infrastructure, particularly for food service and wastewater systems requiring frequent, high-standard intervention. CLEAN SERVICE CO., LTD is structured as an 8H entity with no federal certifications on record. Based on contract locations and award patterns, the company operates primarily in Yokosuka, Japan, serving U.S. military bases in the Indo-Pacific region. Their market positioning is defined by operational continuity in geographically isolated, high-regulation environments where consistent, repeatable sanitation protocols are essential to mission readiness.
