Kankyo Seibi Co.,Ltd.

Kankyo Seibi Co.,Ltd., a Japanese for-profit organization headquartered in Okinawa, provides portable sanitation equipment rental, facility cleaning, grounds maintenance, and waste-collection services to U.S. Department of Defense installations throughout Japan and the Pacific region, operating exclusively as a prime contractor (100% of recent awards) under full-and-open competitive procurement with no set-aside designations.

Kankyo Seibi's customer concentration is heavily weighted toward the Marine Corps and Air Force. The Marine Corps accounts for 125 awards and $21.1 million in combined potential value; the Department of the Air Force Pacific Air Forces follows with 35 awards and $16.1 million. Together, these two customers represent 88% of recent awards by count and 99% by combined potential value. The Department of the Navy, Department of the Army Installation Management Command Pacific Region, and the Air Force Defense Finance and Accounting Service account for the remaining active volume. All work is performed in Japan, supporting U.S. military personnel and base operations at installations including Camp Hansen, Camp Schwab, Kadena Air Base, and White Beach.

Kankyo Seibi operates under two primary indefinite delivery vehicles: a $3.1 million single-award Marine Corps IDV for portable toilet and handwash station rental, cleaning, and relocation services through March 2028, and a $499,998 single-award Air Force Pacific Air Forces blanket purchase agreement for portable latrine and handwash station rentals through September 2026. The Marine Corps vehicle has generated 38 delivery orders; the Air Force vehicle has generated 31 task orders under the broader Marine Corps IDV framework. Three additional Marine Corps IDVs (valued at $10.6 million, $944 thousand, and $789 thousand) drive the bulk of the remaining volume, with individual delivery orders typically ranging from $3,000 to nearly $100,000. Recent representative awards include a $6.75 million Marine Corps delivery order for portable toilet and handwashing station rental and cleaning at Zone 2 locations (awarded February 2026), a $1.96 million Air Force purchase order for military family housing grounds maintenance at the 718th Civil Engineer Squadron (September 2024), a $1.04 million Air Force purchase order for HVAC mini-split and duct cleaning at Pacific Air Forces installations (February 2023), and a $178,474.70 Pacific Air Forces purchase order for exhaust hood and duct cleaning in accordance with NFPA Standard 96 (May 2026).

The capability portfolio centers on janitorial and sanitation services: 112 recent awards fall under NAICS 561720 (Janitorial Services), 65 under NAICS 562991 (Septic Tank and Related Services), and 19 under NAICS 561740 (Other Services to Buildings and Dwellings). PSC coding reflects the same concentration—102 awards under Housekeeping–Custodial Janitorial and 50 under Lease or Rental of Equipment–Toiletries. Services span portable sanitation equipment rental and cleaning, HVAC system cleaning, grounds maintenance, waste collection and disposal, and facility support at military bases.

Activity has been uneven but sustained: four awards in 2022 grew to fourteen in 2023, then declined to six in 2024 and eight in 2025, with five awards placed in 2026 year-to-date. Five awards (combined potential value $3.5 million) reach ultimate completion inside the next twenty-four months, representing moderate recompete exposure centered on Marine Corps vehicle task orders. Kankyo Seibi has received at least one award per year since 2004, indicating established standing and sustained capability demonstration with Pacific-region defense customers. The company operates without identified subcontractors across its federal portfolio.
