KATAYAMA SHOJI INC.

KATAYAMA SHOJI INC. specializes in septic tank collection, inspection, and maintenance services for remote and mission-critical infrastructure sites. Their technical expertise centers on the safe handling, pumping, and regulatory-compliant disposal of wastewater systems, with a focus on environmental sanitation in constrained or sensitive operational environments. The contractor demonstrates proficiency in field-based inspections, system diagnostics, and preventive maintenance protocols tailored to military and defense-associated facilities, ensuring uninterrupted sanitation services in locations with limited utility access. Their work emphasizes adherence to environmental health standards and operational continuity, making them a reliable provider for remote site sustainment. The company has delivered services exclusively to the Department of Defense, specifically supporting communications and logistics sites such as the Owada Communication Site. This indicates a focused relationship with DoD installations requiring specialized off-grid wastewater management, often in areas where municipal systems are unavailable. Their contract performance reflects an understanding of military facility constraints, including security protocols, logistical access limitations, and environmental compliance requirements unique to federal installations. KATAYAMA SHOJI INC.’s primary industry focus is in NAICS 562991 — Septic Tank and Related Services — which encompasses the full lifecycle management of on-site wastewater systems, including pumping, tank cleaning, line inspection, and leach field evaluation. The company positions itself as a niche provider for infrastructure-dependent federal sites requiring reliable, non-municipal sanitation solutions, particularly in isolated or expeditionary environments where conventional sewer systems are impractical. As a 2L entity based in Niiza, Saitama, KATAYAMA SHOJI INC. operates as a small, locally anchored contractor with no federal certifications on record. Their geographic presence is centered in Japan, serving U.S. defense installations in the region. This localized footprint enables rapid response and cultural alignment with DoD facility operations in the Asia-Pacific theater, establishing them as a specialized, regionally embedded provider for critical sanitation infrastructure.
