About the company
Nakasho Inc., a for-profit corporation headquartered in Kanagawa, Japan, provides medical and animal waste collection, transportation, and disposal services to the Department of Defense as a prime contractor, competing full-and-open with no set-aside designations across a limited federal footprint.
The vendor's federal customer base centers on defense health and medical operations. All five awards in the source data flow from three agencies — the Defense Health Agency (3 awards, $309 thousand combined potential value), the Defense Finance and Accounting Service (1 award, $102 thousand), and the Department of the Army Medical Command (1 award, $26 thousand) — with the Defense Health Agency anchoring 71% of combined potential value. The vendor holds a single Indefinite Delivery Contract (FA520925D0002) with the Defense Health Agency, established October 6, 2024, with a $264,183 ceiling extending through October 5, 2034. Two delivery orders have been issued under this IDC: a $22,863.85 firm fixed-price order awarded October 18, 2024, scheduled for completion by October 5, 2025, and a $22,148.15 order awarded October 21, 2025, extending through October 5, 2026. Both task orders target hazardous waste management at Defense Health Agency facilities in Japan. The vendor's NAICS profile aligns with its work — four of five awards fall under Hazardous Waste Treatment and Disposal (NAICS 562211), with one order classified under Other Nonhazardous Waste Treatment and Disposal.
Activity is sparse and episodic. The vendor received its first award in October 2014, then one award in 2019, then two in 2024 and one in 2025, yielding $437 thousand in combined potential value across all awards and $172 thousand obligated to date (39% of ceiling). One award faces ultimate completion in the next twenty-four months ($22 thousand potential value), but the IDC itself extends a decade out, providing contract stability absent near-term recompete pressure. Nakasho operates exclusively as a prime — no subcontract activity appears in the source data.
